High-grade carbon steel

65Mn

65Mn low-alloy round steel must have a high elastic limit and high flexural strength ratio to avoid permanent deformation of spring steel under high load. At the same time also requires good hardenability and low sensitivity to decarbonization, so that the elastic limit greatly reduced; As well as good surface quality, in the hot and cold state of easy processing and good heat treatment technology.

#50

#50 steel is a medium carbon high-strength carbon structural steel, after quenching with high strength and hardness, the steel machinability of medium, low cold deformation plasticity, poor weldability, heat treatment without tempering brittleness, but the hardenability is low, the critical diameter in water is 13*30mm, and water quenching has a tendency to crack. This steel is usually used after heat treatment such as normalizing or quenching tempering, or high-frequency surface quenching. No. 50 steel can be hardened to HRC42~46. Therefore, if the surface hardness is needed, and you want to play the superior mechanical properties of No. 50 steel, the surface of No. 50 steel is often carburized and quenched, so that you can get the required surface hardness.

#45

45# steel pipe is usually suitable for seamless steel pipe material, seamless steel pipe is divided into GB8162, GB8163 these two commonly used, but 45# steel only GB8162, 45# is a commonly used material for mechanical processing.he carbon content of 45# steel pipe is about 0.45%, containing a small amount of manganese, silicon, etc., and high-quality carbon structural steel with low sulfur and phosphorus content.

#60

No. 60 steel is hypoeutectoid steel, with high strength, hardness and elasticity, low plasticity when cold deformation, poor machinability, poor welding and hardenability, water quenching has a tendency to crack, and large parts are mostly normalized. No. 60 steel is used to manufacture shafts, spring rings, wheel shafts, various gaskets, cams, steel ropes and other parts with large forces and working under friction conditions, requiring high strength, wear resistance and certain elasticity.
