Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the A572 Gr 65 high strength steel, steel plates and strips used for stamping must have qualified stamping performance.
The chemical composition difference between A572 Gr 65 high strength steel, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between A572 Gr 65 high strength steel, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry. Our logistics service team will make sure our goods delivered to the leaving port on time.Makes you worry-free after sales.
