Features of Q235NHA sheet:Q235NH steel sheet has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving. It has a long service life when used in harsh environments. It has a protective rust layer to resist atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere.
Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of SA573 Grade 70 raw material, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.
we also provide the SA573 Grade 70 raw material welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful SA573 Grade 70 raw material welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate SA573 Grade 70 raw material after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our SA573 Grade 70 raw material steel mill.
