42CrMo4, 4140, and SCM440

42CrMo4, 4140, and SCM440 are different designations for the same or similar types of steel, which is a high-alloy, medium-carbon chromium molybdenum steel. This type of steel is known for its high strength and hardenability, making it suitable for a variety of applications that require strong and wear-resistant components.

SAE 8620H

SAE 8620H is a type of low-alloy steel that is known for its good strength and toughness, as well as its excellent hardenability.SAE 8620H steel is commonly used in applications where parts require a hard, wear-resistant surface and a tough, strong core.

Q215/E195/1.0034

Q215/E195/1.0034 is a low carbon steel with good strength, formability and weldability. It is generally used to produce cold-formed parts, pipes and other products that require moderate strength and easy processing.
They are widely used in applications that require easy forming, welding and not too high loads.

GB 40Mn2

GB 40Mn2 is a widely used medium carbon structural steel with good strength, toughness and ductility, suitable for manufacturing components subjected to medium to high stress and impact. It can be heat treated so that the mechanical properties can be tailored to the specific requirements of the automotive, machinery and construction industries.
