OEM service high quality hardox 500 chemical composition
The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.
At present, the design of oil and gas HARDOX 500 chemical composition pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of HARDOX 500 chemical composition steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. HARDOX 500 chemical composition, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
The wear-resistant layer of HARDOX 500 chemical composition wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy HARDOX 500 chemical composition carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
