Welding grade SA283 Gr D carbon steel plate sheet equivalent astm material

It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products SA283 Gr D carbon steel plate sheet , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.

Our company supply low-alloy high-strength structural steel common grades below: Q345B / C / D / E, A572Grade 50 sheet, A572Gr.55 plate, SA283 Gr D carbon steel plate sheet, A514 Grade B material, A709 Grade 50 steel. The company can provide low alloy structural steel plate thickness range of 6 ~ 200mm. Our low-alloy high-strength steel is widely used in various types of engineering structures such as steel structure construction, construction machinery, mining machinery, heavy vehicles, bridges, pressure vessels.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. SA283 Gr D carbon steel plate sheet, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the SA283 Gr D carbon steel plate sheet steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
