Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional A573 steel plate production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of A573 steel plate leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
Characteristics and application scope of A573 steel plate, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.
We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days. Meanwhile, our weathering steel price is competitive. And for weathering steel coils, we do slit, A573 steel plate plate cut and so on further processing. We can meet different size and shape needs of customers.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the A573 steel plate quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After A573 steel plate quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, A573 steel plate, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
Our company will accept the product quality objection registration record, pass it to the A573 steel plate production unit and relevant departments, and timely coordinate the supervision of product A573 steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
