Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.
Q960D quenched and tempered high-strength steel is used to make pressure shell parts, deep tide lifesavers, high-pressure structural parts, aerospace equipment, armored vehicles, and manufacturing various engineering machinery, such as drilling rigs, electric shovel, and Electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and wear-resistant structural parts.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. A572 Gr 50 CS steel carbon plate, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10).
