A299 Gr.B steel properties

Mechanical function: strength, hardness, plasticity, fatigue, impact toughness of A299 Gr.B steel plate are guaranteed.

Chemical function: corrosion resistance, high temperature oxidation, A299 Gr.B raw materials are guaranteed, and the chemical composition can be tested and used.

Physical functions: density, melting point, thermal expansion, magnetism, electrical conductivity. SA-299MGr.B can be guaranteed under special conditions.

Process function: cutting function, forgeability, castability, weldability. SA-299MGr.B process function can carry out spot cutting

A299 Gr.B plate is often used to make various welded parts whose working temperature does not exceed 400 degrees Celsius, such as the head and shell of boiler steam drum, and pressure vessel. Due to its working environment, A299 Gr.B plate is required to have a higher medium temperature, outstanding shaping and heat treatment process functions, and outstanding welding functions.
