Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and A572 grade 55 ms steel coil heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported A572 grade 55 ms steel coil to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
Characteristics and application scope of A572 grade 55 ms steel coil, 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 ℃.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A572 grade 55 ms steel coil, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
The A572 grade 55 ms steel coil, wear-resistant plate after VD treatment is generally high-quality wear-resistant plate with high added value. In addition to the strict requirements for the composition of wear-resistant plate, the requirements for the anti-fatigue pull-out damage performance of the wear-resistant plate are also very strict. Therefore, the non-metallic inclusions, especially the large non-metallic inclusions and brittle inclusions, must be strictly controlled.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The A572 grade 55 ms steel coil, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think! Our quality is better for the A572 grade 55 ms steel coil same products, our price is lower for the same quality, and our service is better for the same price. welcome to purchase steel materials from our company. we have the professional team and good after-sale system to customers. our company A572 grade 55 ms steel coil is your best choose.
