We have a very A573 Gr 70 carbon steel plate extensive commodity information network, with partners all over the world, and have become the full authority of many European and American traders in China. Under the guidance of the business philosophy of "creating the best service" and through the unremitting efforts of all employees, we have achieved remarkable results.
High weather resistance structural steel Q295GNH, Q355GNH adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal to improve the steel with atmospheric corrosion resistance. High weather resistance structural steel is mainly used in the structure of vehicles, containers, buildings, towers or other structural parts. Compared with welded structural steel A573 Gr 70 carbon steel plate, it has better atmospheric corrosion resistance.
Different form A573 Gr 70 carbon steel plate, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.
The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, A573 Gr 70 carbon steel plate. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
A573 Gr 70 carbon steel plate, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
The alloy steel plate is among our business scope, and it is one of our main product.
