hardox 500 steel yield strength color coated steel sheet
At the same time, the company operates a variety of products of related iron and HARDOX 500 steel yield strength steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained HARDOX 500 steel yield strength ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
SA299 Gr.B steel is C-Mn-Si steel plate often used to make various welding parts whose working temperature does not exceed 400 degrees Celsius, such as the head and shell of boiler steam drum, pressure vessel. Due to its working environment, SA299 Gr.B plate is required to have a higher medium temperature, outstanding shaping and heat treatment process functions, and outstanding welding functions.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate HARDOX 500 steel yield strength has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized HARDOX 500 steel yield strength are higher than that of annealed HARDOX 500 steel yield strength, but the elimination of internal stress is not as good as annealing. The normalizing operation of HARDOX 500 steel yield strength is simple, the cost is low, the productivity is high, and it is widely used in actual production.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, HARDOX 500 steel yield strength. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel HARDOX 500 steel yield strength products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
