GCr15SiMn bearing steel

GCr15SiMn bearing steel is a kind of high carbon chrome steel produced and processed in accordance with the national standard. In reality, GCr15SiMn bearing steel has excellent comprehensive performance, wide and excellent hardenability, GCr15SiMn bearing steel has great fatigue strength, high mechanical strength and corrosion resistance.

GCr15SiMn bearing steel contains 1.00-1.30% carbon and 0.35%-0.40% silicon, 0.50-1.60% chromium and 1.00-1.40% manganese. GCr15SiMn bearing steel, especially silicon and manganese, can improve its hardenability. When the temperature is above 850 degree centigrade, GCr15SiMn Bearing Steel can produce martensite very fast.

GCr15SiMn bearing steel, as a medium carbon bearing steel, has properties of both low and high carbon bearing steel. It is used in some special applications and can replace high carbon bearing steel to some extent. Compared to high carbon bearing steel, GCr15SiMn bearing steel can reduce production cost.

The tensile strength and yield ratio of GCr15SiMn bearing steel are both slightly higher than low carbon bearing steel. It has markedly higher strength after heat treatment. The bearing steel has good toughness and even in the case of a large cross-sectional size and a small radial size. GCr15SiMn bearing steel has better stable performance, when the shape and size accuracy are lower than high carbon bearing steel. It can be heat-treated to Bearing hardness of 60-64 HRC.

GCr15SiMn bearing steel is widely used in high speed and medium speed bearing, roller and other rolling machine components, such as automobile, machine tools, and agricultural tools etc. In the clutch bearing, tapered roller bearings and other products, GCr15SiMn bearing steel is usually used in heavy load and high speed occasions.

Due to its excellent comprehensive performance, GCr15SiMn bearing steel are widely used in various kinds of manufacturing processes. Moreover, it is also a famous bearing material in some high-end bearing manufacturing industry. Therefore, GCr15SiMn bearing steel is quite suitable for the application of bearing rings and rolls.

In conclusion, GCr15SiMn Bearing Steel is an excellent bearing steel with a variety of structural and mechanical properties. Its fatigue strength, mechanical strength, corrosion resistance and excellent hardenability are all necessary properties for bearing steel, and make GCr15SiMn Bearing Steel an ideal material to be used in high speed and medium speed bearing, roller and other rolling machine components.

GFGCr15SiMn is a kind of bearing steel widely used in the world, it is also called bearing steel st45. GFGCr15SiMn(bearing steel st45) is developed on the basis of GCr15 Bearing steel, adding alloying elements of silicon, manganese and the carbon content is 0.95-1.10%.

GFGCr15SiMn has good comprehensive performance, high hardenability and uniform carbide distribution. In addition, it also has medium hardening, good wear resistance, higher impact toughness and good fatigue strength.

GFGCr15SiMn has good machinability, and its hardening deformation is small. This kind of bearing steel can obtain high hardness and medium wear resistance and fatigue strength after quenching and quenching, so it is widely used in all kinds of bearing manufacturing industries with the highest requirement. The comprehensive performance of bear steels such as microstructure, uniformity, hardness and wear resistance and fatigue strength will directly affect the performance and life of bearings, so the performance requirements of bearing steels are higher.

GFGCr15SiMn bearing steel is usualused for manufacturing steel balls, bearing seats and other parts that require high wear resistance, such as bushings, wheels and other parts that require high dimensional accuracy and high surface quality.

In short, the use of GFGCr15SiMn bearing steel has no doubt that its comprehensive performance has been improved and it has strong comprehensive performance and wear resistance. Therefore, GFGCr15SiMn bearing steel has been widely used in all kinds of bearing manufacturing industries.
