Carbon Structural Steel
Carbon structural steel is an engineering material made of iron and carbon. Its characteristics are good plasticity, toughness, strength, good weldability, ease of processing and good corrosion resistance. Carbon structural steel is often referred to as mild steel because of its low cost, high ductility and good weldability. It can be used for making various parts and products.
Carbon structural steel is divided according to the different alloying elements contained in the steel. Generally speaking, there are plain carbon steel, low alloy steel, high alloy steel, alloy tool steel and other special steel. Plain carbon steel is the most widely used type of carbon steel, which is also called ordinary carbon steel. It contains 0.16-2.10% carbon, and is divided into low carbon steel (0.16-0.25% carbon), medium carbon steel (0.25-0.60% carbon) and high carbon steel (0.60-2.10% carbon). Low carbon steel is suitable for making parts with smaller strength requirements, while medium and high carbon steel is suitable for making parts with higher strength requirements.
Low alloy steel contains a higher percentage of alloying elements than plain carbon steel. Adding certain alloy elements to low carbon steel can improve the strength, toughness and other properties of the steel. Low alloy steel is divided into low alloy high strength steel, low alloy heat resistant steel, low alloy corrosion resistant steel, low alloy wear resistant steel and other types. Low alloy high strength steel is a kind of steel with high strength, good toughness and good weldability. Its alloying elements are usually silicon manganese and vanadium nitrogen.
High alloy steel contains a higher percentage of alloying elements such as chromium, cobalt, tungsten, molybdenum and niobium. Generally speaking, high alloy steel has good wear resistance, heat resistance and corrosion resistance. It is suitable for making parts which need these properties. High alloy steel is divided into two categories: cold-working alloy steel and hot-working alloy steel.
Alloy tool steel contains alloying elements such as chromium, molybdenum, tungsten, vanadium and cobalt. It is great for making tools which are used to cut, mold and form other materials. Alloy tool steel is divided into cold-working tool steel, hot-work tool steel and plastic mold steel.
Carbon structural steel has many applications. It is widely used in automotive, shipbuilding, large manufacturing and construction industry, bridges, etc. It is also used to make agricultural tools, hardware products and other civilian daily necessities.
Carbon structural steel is an important engineering material. Its properties and applications determine its widespread use in many industries. Considering its advantages, it is important to select suitable carbon structural steel according to the actual situation. This can make the products efficient, reliable and safe, and enhance the competitiveness of the industry.
