What is the a656 grade 50 material properties flaw detection process

The company attaches great importance to systematic management, and has passed the a656 grade 50 material properties ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on a656 grade 50 material properties quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. a656 grade 50 material properties It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length a656 grade 50 material properties is suitable for the length required by the construction of steel pipes.

Different from a656 grade 50 material properties, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.

Chemical composition of a656 grade 50 material properties, Q345D steel plate: C: ≤0.18; Si: ≤0.50; Mn: ≤1.70; P: ≤0.030; S: ≤0.025; Nb: ≤0.07; V: ≤0.15; Ti: ≤0.20; Cr: ≤0.30; Ni: ≤0.50; Cu: ≤0.30; N: ≤0.012; Mo: ≤0.10; Als: ≥0.015. Yield strength (MPa) of Q345D steel plate: ≤16mm: ≥345; 16-40mm: ≥335; 40-63mm: ≥325; 63-80mm: ≥315; 80-100mm: ≥305; 100-150mm: ≥285; 150-200mm: ≥275; 200-250: ≥275; 250-400: ≥265. Tensile strength of Q345D low alloy steel: 450-630(MPa). Elongation: ≥21. Impact test: -20 ℃: ≥34.
