Hot sales ship building carbon steel JIS SM400A plates

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, JIS SM400A plates quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the JIS SM400A plates International leading steel materials supplier.

Steel plates for oil and gas pipelines: X42 (L290), X46 (L320), X52 (L360), X56 (L390), X60 (L415), X65 (L450), X70 (L485), X80. Executive standard: API -5LB (L245). Main purpose: used to make oil and natural gas pipelines. API 5L generally refers to the pipeline steel plate-API 5L pipeline steel plate. The pipeline steel plate is processed into large-diameter pipeline steel pipe to transport the oil, gas, and water extracted from the ground through the pipeline pipe to the oil and natural gas industrial enterprises.

The alloy steel plate has higher oxidation resistance and corrosion resistance, and is more suitable for use in acid and alkali environments. The surface of alloy steel plate will not be oxidized and corroded, maintaining the brightness of the steel plate. The alloy steel plate also has high material strength, its pressure bearing performance is very outstanding. It has high plasticity under the condition of long-lasting stretching. The JIS SM400A plates, alloy steel plate is not prone to fracture, and it is more durable.

S355NC steel offers excellent bending, flanging, cold-bordering and folding JIS SM400A plates properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

The difference between JIS SM400A plates, 10# seamless steel pipe and 20# seamless steel pipe: 1. Chemical composition Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25 2. Mechanical properties 10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
