ASTM A479/A479M 410 Condition 1 Introduce
The mechanical properties of ASTM A479/A479M 410 Condition 1 boiler steel depend on the grade and the heat treatment used during manufacturing. Generally, the higher the grade, the greater the strength and resistance to deformation and failure under high temperatures and pressures.
The primary application of ASTM A479/A479M 410 Condition 1 boiler steel is in the manufacturing of boilers, which are pressure vessels used to generate steam or heat water for industrial processes. Boilers are commonly used in industries such as power generation, chemical processing, and food processing.
Smelting temperature:1494°C - 1726°C
Application:Stainless steel and heat-resistant steel bars and profiles for boilers and pressure vessels
