Steel company in Vietnam produce steel in multiple types. Here is a list of some of them.
Carbon steel
Carbon steel is a common type of steel in Vietnam. It chemical composition is mostly iron and carbon. The amount of carbon used determines the type of carbon steel. Low carbon steel, also known as mild steel has a carbon content of 0.05% to 0.25%. Medium carbon steel contains 0.3% to 0.6% carbon. High carbon steel has 0.6% to 1.0% carbon.
Since mild steel has a low carbon content, it is malleable and ductile which makes it ideal for structures. Medium carbon steel strikes a balance between strength and ductility. It is ideal in automotive components which require both rigidity and flexibility. High carbon steel, with its high carbon content, is hard and tough. It is often used in making blades, wires and other tool that require edge retention.
Alloy steel
Vietnamese steel company makes alloy steel by adding elements such as manganese, nickel, chromium and vanadium to iron and carbon. These elements enhance properties such as strength, hardness and resistance to wear. Manganese improves resistance to impact and corrosion. This makes the steel suitable for construction and automotive industry.
Nickel increases toughness and resistance to low temperatures. This makes nickel alloy steel ideal for machinery in cold climates. Chromium raises hardness, tensile strength and elasticity. This makes the steel useful in aerospace and automotive components. Vanadium, on the other hand, refines grain structure. This improves strength without hampering ductility.
Stainless steel
Often customized, stainless steel is a type of steel that is resistant to rust. It achieves this property by adding a minimum of 10.5% chromium and other elements like nickel, molybdenum and vanadium to the alloy. This steel is aesthetic making it useful in architecture and design to obtain shiny surfaces that don't require frequent maintenance. Due to its non-reactive property, it is suitable for medical equipment and food processing units.
High strength low alloy steel
Vietnamese steel suppliers use a small amount of rare elements such as copper, nickel and chromium in hsla to increase its strength and durability. The small amount of alloying elements makes hsla steel exhibit excellent weldability and formability. Manufacturers in Vietnam make automobile bodies, pipelines for energy transmission and construction materials from hsla steel.
Tool steel
Vietnamese tool steel suppliers make tool steel from a combination of elements such as tungsten, molybdenum, vanadium, cobalt and chromium. These elements, added to carbon and iron, provide the steel with hardness, abrasion resistance and retentiveness of its shape under high temperature. This makes the steel ideal for manufacturing cutting tools, dies, molds and chisels.
Steel has multiple features. Here is a rundown of some of them.
Durability
Steel is tough and therefore can withstand wear, tear and damage. It has a long lifespan and retains structural integrity for many years. Vietnamese steel has premium durability making it ideal for heavy construction projects, automotive parts and industrial machinery.
Strength
Steel possesses a high tensile strength. It is able to support huge loads without deforming or breaking. This property enables steel to be used as a main material in making beams, columns and reinforcement bars for buildings and bridges in Vietnam.
Corrosion resistance
Addition of alloys, such as chromium to make stainless steel, improves the resistance of steel to rust and corrosion. This quality makes steel a preferred material for outdoor constructions such as buildings, bridges and highway overpasses that are constantly exposed to moisture and environmental elements.
Versatility
Vietnamese manufacturers use steel in various industries such as construction, automotive, machinery, aerospace and shipbuilding, among others. Steel's adaptability in these industries arises from its varying grades and types which are suited to specific applications. They range from carbon steel for basic structures to high-alloy steel for high-performance engine components.
Cost-effectiveness
Although steel is expensive when making it requires huge initial capital, it is easily obtainable. Its availability and relatively low processing cost make it an economical choice for large-scale construction projects, automotive production and manufacturing of machinery.
Unified recycling
Steel is 100% recyclable without losing its inherent properties. This quality allows it to contribute to sustainable practises in construction and manufacturing. It allows manufacturers in Vietnam to recycle scrap steel and thus reduce costs, resource consumption and environmental impact.
Steel has multiple uses. Here is a list of its appellations.
Construction
Steel is used to make beams, columns, reinforcements and metal roofing in construction due to its strength, durability and ability to support heavy loads. Reinforced concrete which is used in almost all buildings and structures, in addition, contains steel bars (rebar) for increased tensile strength. Builders also prefer steel frames for the strength and ability to withstand forces. This makes them ideal for skyscrapers and high-rise buildings.
Automotive industry
Steel, with the addition of carbon, makes it malleable and durable, is ideal for constructing vehicle bodies, chassis and engines. The most common steel used is mild steel which is formed into complex shapes and welded. Thus, it is used in making outer panels and structural supports.
Vietnamese manufacturers use high-strength steel to produce parts that require greater strength and durability, such as suspension components and frames. They also use mild steel for making internal components, like engine parts and exhaust systems. Steel is also used to make automobile fasteners, including bolts and screws, that require tensile strength and resistance to deformation.Shipbuilding
Vietnamese steel manufacturers use steel, particularly carbon and alloy steels, in shipbuilding to provide strength and durability to vessels. Steel's resistance to waves, salt water and weathering, makes it ideal for constructing hulls, frames and decks of ships and boats used for fishing, transportation and military operations.
Machinery and industrial equipment
Steel, especially alloy steel, is commonly used to manufacture industrial machinery and equipment as it withstands wear, tear, pressure and extreme temperatures occurring in industrial settings. This makes it ideal for manufacturing gears, shafts and bearings, the components which require high strength and hardness. Steel sheets are used to make pressure vessels and reactors that are used in storing and processing chemicals in chemical and petrochemical industry.
Aerospace
In aerospace industry, steel is used to make landing gear, engines and fuselage components. Though lighter materials like aluminum and titanium are preferred in some applications, alloy steels find their usage in parts that require high strength and fatigue resistance. This makes them ideal for commercial and military aircraft.
Agriculture
Manufacturers in Vietnam make farming tools and equipment, including plows, harrows, tractors and combines, from steel. Steel's flexibility and strength enable it to withstand heavy loads, bending and stretching. This makes it suitable for producing both hand tools and large agricultural machinery involved in tilling, planting, and harvesting crops.
Steel comes with varied grades, sizes and compositions. Thus, choosing steel can be daunting. However, the following factors can help one settle for the ideal steel in Vietnam.
Purpose
One should consider the use of the steel to determine its type. For instance, if the steel is meant to be used in construction, one should go for mild steel with low carbon composition for easy workability. On the other hand, if the steel is meant for tool making, there is a need to settle for steel with high carbon composition for high strength.
Rust resistance
If the steel is meant for outdoor purposes, one should opt for stainless steel, which is rust resistant due to the high amount of chromium. Also, carbon steel is usually heat treated to increase its rust-resistant properties.
Formability and tensile strength
Formability is the process of shaping steel, while tensile strength is the ability of steel to carry weight without rupturing. Therefore, one should check the elongation percentage on the steel to ensure it can stretch without tearing when forming it. Moreover, buyers should also check the yield strength and ultimate tensile strength for better handling and welding.
Thermal treatment
Depending on the buyer's preference, steel can be delivered in a normalized state, annealed and quenched. For example, steel that is in a normalized state is a little more usable than quenched steel, which is very hard and tough. There is also annealed steel, which is rust resistant and easy to handle.
Cost
Normally, galvanized steel is more expensive than regular carbon steel. Therefore, buyers should decide on the type of steel based on their budget.
Although stainless steel is rust resistant, it is usually more expensive than regular carbon steel. Moreover, it is more difficult to weld.
Steel with a low carbon composition, commonly known as mild steel, is the most common steel used in construction. It is easily workable and rust resistant.
High strength low alloy steel is usually fabricated with a small amount of mineral. This makes it possible to manufacture even with less mineral exploitation. Moreover, HSLA steel is usually recyclable.
Unlike alloy steel, which has alloy metals such as manganese and chromium added to it, carbon steel only has carbon added to it. Therefore, steel's properties depend on the amount of carbon and alloy elements in each steel type.
