Is steel grade ASTM A36 and sa573 gr.58 carbon steel iron plate are equal?

With high-quality sa573 gr.58 carbon steel iron plate steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our sa573 gr.58 carbon steel iron plate steel market and improved the control of steel plate production quality.

A709Gr50 steel is a high-strength low-alloy stee. It is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for those requiring good weldability and toughness Construction and construction machinery parts. BBNsteel’s engineers suggest customer choose low temperature impacting test for steel A709 grade 50 at zero centigree, because these steel plates A709Gr50 normally used in this temperature.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they sa573 gr.58 carbon steel iron plate work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

In order to prevent the deformation of sa573 gr.58 carbon steel iron plate, wear-resistant composite plate during preheating, the steel plate with good quality should be selected first. The steel plate with serious carbide segregation should be reasonably cast and heat treated by quenching and tempering. For the large and non cast wear-resistant composite plate, the solution double refining heat treatment can be carried out. At the same time, the heating temperature should be reasonably selected and the heating speed should be controlled.

Q355B steel and sa573 gr.58 carbon steel iron plate steel
Both Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.

BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For sa573 gr.58 carbon steel iron plate ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the sa573 gr.58 carbon steel iron plate standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
