We have gradually formed four advantageous products of steel plate, steel pipe, ASTM A573 Grade 58 structural steel plate, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.
40Cr steel belongs to alloy structural steel. ASTM A573 Grade 58 structural steel plate, 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.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and ASTM A573 Grade 58 structural steel plate pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
