Material requirement for A709 grade 50 carbon steel plate sheet HR plates

The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of A709 grade 50 carbon steel plate sheet pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and A709 grade 50 carbon steel plate sheet special properties such as good formability, weldability and adaptability to welding process.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for A709 grade 50 carbon steel plate sheet various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several A709 grade 50 carbon steel plate sheet after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

The carbon content of A709 grade 50 carbon steel plate sheet, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, A709 grade 50 carbon steel plate sheet. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.

Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed A709 grade 50 carbon steel plate sheet materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
