What type of steel is 4140 steel?
4140 alloy structural steel, executive standard: ASTM A29/A29M-04, is a low alloy steel containing chromium, molybdenum and manganese. It is a medium hardenability steel. It has good strength and good comprehensive mechanical properties after heat treatment. Good craftsmanship and high yield rate.
4140 alloy structural steel is an alloy steel with the grade 4140 and a carbon C of 33 to 48. Due to its toughness, high fatigue strength, wear resistance and impact resistance, it is widely used in many industries and is an excellent material selection.
AISI4140 alloy structural steel is a common high-strength steel, corresponding to my country's GB standard steel number 42CrMo4. This material is a type of alloy material. Its carbon content is more than 33% and less than 48%, and its hardness is as high as 241HB. It also has Very strong tensile strength. In addition, this alloy steel also has good mechanical properties and wear resistance, and has good gloss after grinding.
