sa573 gr 70 high strength structural steel heat treatment

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. sa573 gr 70 high strength structural steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

In the cutting process of wear-resistant plate, sa573 gr 70 high strength structural steel, the steel plate is processed first, because the steel plate is cut after cutting and marking; the commonly used cutting methods for wear-resistant plate are CNC flame cutting and numerical control water cutting, the cost of numerical control flame cutting is not very high, it belongs to primary processing, and its processing range is from 3 mm to 100 mm steel plate. And numerical control water cutting is mainly used under the condition that cutting is required not to deform.

The sa573 gr 70 high strength structural steel company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest sa573 gr 70 high strength structural steel teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.
