ASTM A479/A479M N08926 Introduce

ASTM A479/A479M N08926 pressure vessel steel is preferred in these industries because of its high strength and corrosion resistance. This steel has a higher yield and tensile strength than other types of steel, making it more resistant to deformation and structural failure under high pressure. Additionally, the steel's resistance to corrosion makes it highly durable and long-lasting, even in harsh environments.

Smelting temperature:1138°C - 1674°C

Application:Stainless steel and heat-resistant steel bars and profiles for boilers and pressure vessels
