40Cr alloy structural steel, Baosteel produced the first choice for Shanghai Tang heavy industry and trade

40Cr of China GB standard steel, 40Cr steel is the most widely used one of the steel in machinery manufacturing. Quenched with good mechanical properties, excellent low temperature impact toughness and low notch sensitivity. Hardenability of steel, water quench hardenability Ф28 ~ 60mm, oil quenching hardenability to Ф15 ~ 40mm. This steel is also suitable for addition to the quenching and tempering treatment of cyanide and high frequency quenching treatment. Cutting performance is better, when the hardness HB174 ~ 229, the relative machinability of 60%. The steel is suitable for the production of medium-sized plastic mold.

Shanghai Tang Heavy Industry Co., Ltd. look forward to your call

Shaft parts is often encountered in typical machine parts. It is mainly used to support the transmission parts, transmission torque and load bearing. Shaft parts are parts of the rotating body, and its length is greater than the diameter of generally concentric axis of the outer cylinder, a conical surface, the inner hole and thread, and the corresponding end. Depending on the structure and shape, the shaft parts can be divided into the optical axis, stepped shaft, hollow shaft and crankshaft and so on.
