A573 Gr 70 structural steel
A573 Gr 70 structural steel,The alloy wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbide in the metallographic structure is fibrous, and the fiber direction is perpendicular to the surface; alloy carbide It has strong stability at high temperature, maintains high hardness, and also has very good anti-oxidation performance. A573 Gr 70 structural steel, wear-resistant steel plate can be used normally within 500 ℃.
A573 Gr 70 structural steel,304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
A573 Gr 70 structural steel,Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
