SA709 Gr 50 carbon steel plate sheet for engineering

ASME SA516 GRADE 70 boiler steel plates are of the best quality and are, therefore, one of the most preferred steel grades in the market. It is remarkably resistant to corrosion and deterioration and also repellent to erosion and thus is convenient to be used in various conditions. These plates SA709 Gr 50 carbon steel plate sheet are primarily intended for use in conditions wherein supreme strength and durability are required. These ASME SA516 GR 70 plates offer the highest yield and tensile strength range. And, the boiler quality plates offer the highest utility and are also exceptionally reliable.

We are world class steel materials supplier. We are engaed in providing raw steel materials such as SA709 Gr 50 carbon steel plate sheet steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build SA709 Gr 50 carbon steel plate sheet long-term cooperation with you.

Quenching Improve the hardness of SA709 Gr 50 carbon steel plate sheet steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of SA709 Gr 50 carbon steel plate sheet steel and comprehensive mechanical properties.

Chromium element (Cr element) can improve the strength and hardness of SA709 Gr 50 carbon steel plate sheet, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel SA709 Gr 50 carbon steel plate sheet products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
