ASTM A573 Grade 58(A573 Gr 58) sheet rolling process

50Mn2 seamless steel pipe is a kind of high-strength medium-carbon quenched and tempered manganese steel. It has high strength, elasticity and wear resistance. At the same time, ASTM A573 Grade 58(A573 Gr 58) sheet product has high hardenability. The critical hardenable diameter in oil is 10-28mm. The critical hardening diameter is 24～49mm, and the machinability is fair.

Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. ASTM A573 Grade 58(A573 Gr 58) sheet, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.
