40Cr steel belongs to alloy structural steel. SA573gr70 high strength carbon steel, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with SA573gr70 high strength carbon steel SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent SA573gr70 high strength carbon steel products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the SA573gr70 high strength carbon steel technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
