Steel Material

45 steel

45 steel is the name in GB, also called “oil steel”, this steel has higher strength and better machinability.

Material advantages:

It has high strength and good machinability. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. The material source is convenient. It is suitable for hydrogen welding and argon arc welding.

40Cr steel

40Cr is the standard steel grade of my country’s GB, and 40Cr steel is one of the most widely used steels in the machinery manufacturing industry.

Material advantages:

It has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity. The hardenability of steel is good, this steel is suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment. The cutting performance is better.

Q235 steel

Q235 steel is a kind of carbon structural steel, and the Q in its steel grade stands for yield strength. Normally, the steel is used directly without heat treatment.

Material advantages:

As the thickness of the material increases, its yield value decreases. Due to the moderate carbon content, the overall performance is better, and the strength, plasticity, and welding properties are better matched, and it is the most widely used.

SUS304 steel

SUS304 refers to 304 stainless steel, which has the characteristics of good processing performance and high toughness.

Material advantages:

It has good corrosion resistance, heat resistance, corrosion resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening phenomenon, and non-magnetic.
