20SiMnVB Structure Steel

20SiMnVB structure steel is a kind of high-end martensitic steel, which contains 0.20% carbon, 0.80% silicon, 1.50% manganese and 0.035% nitrogen. The steel has good performance in toughness, strength and fatigue resistance, and its HRC can reach 38-44. This type of steel is usually used for making parts with high accurately requirement, such as gears and heavy-duty axle housing.

This kind of steel is formed by two technological process – secondary refining and electroslag remelting. Secondary refining enables the elimination of impurities and improvement of chemical composition, while electroslag remelting ensures the homogeneity of steel structure and guarantee the excellent performance. In order to make the internal structure more reasonable, the steel contains a reasonable tough segment, reasonable hard segment and high strength phase, which give it better comprehensive properties.

In comparison with common martensitic steels, 20SiMnVB structure steel has higher fatigue strength, superior toughness, higher temperature strength and better corrosion resistance. It can be used in working environment with temperature of 850℃ for long period, and has good performance in resisting stress corrosion and medium strength corrosion. The steel also has good welding performance, and can be joined by welding.

20SiMnVB structure steel is widely used in shipbuilding, metallurgy, aerospace, mold and other fields. Its superior performance and light weight make it an ideal material for manufacturing various turbines, bearings, gears and other components. In addition, its good performance in fatigue and corrosion resistance and wide temperature range have enabled it to be widely used in equipment of chemical, nuclear and other special industry.

20SiMnVB structure steel is an excellent material with superior performance and light weight. It is widely used in various fields, such as shipbuilding, aerospace, metallurgy and others, due to its excellent properties. The steel has good performance in toughness, strength and fatigue resistance, and its HRC can reach 38-44. It has higher fatigue strength, superior toughness, higher temperature strength and better corrosion resistance. In addition, it has good welding performance and can be joined by welding. With these superior performance, it can be used for producing gears, bearings and other components in various fields.

20SiMnVB Alloy Structural Steel

20SiMnVB Alloy Structural Steel (alloy grade: 20SiMnVB) is a high-end alloy steel with excellent mechanical properties, which has been widely used in automobile, ships, aircraft and engineering machinery industry.

20SiMnVB has good machinability and weldability, and it is usually used for making forging parts and components due to its good forging performance. 20SiMnVB Alloy Steel is an excellent choice for producing components with large dimensions, high load and high temperature requirements, such as engine parts, crankshafts, camshafts, drive shafts, forged gears, drive chains, piston connecting rods and other structural parts of the vehicle.

20SiMnVB Alloy Steel also has excellent chemical composition, mainly containing carbon, manganese, silicon, molybdenum, vanadium, chromium, phosphorus and sulfur. The structure of 20SiMnVB is a mixture of quenched-tempered and strengthened-tempered structure, which has excellent performance and is more resistant to plastic deformation than ordinary carburizing steel.

In terms of mechanical properties, 20SiMnVB Alloy Steel has high strength and hardness, good wear resistance and fatigue strength, high temperature resistance and toughness properties, and good thermal strength and excellent tensile strength, making it suitable for a wide range of high-stress working conditions.

In a word, 20SiMnVB Alloy Steel is an ideal choice for producing components with large dimensions, high load and high temperature requirements, and it will be more and more widely used in automobile, ships, aircraft and engineering machinery industry.
