SA299 Gr.B steel main features

SA299 Gr.B steel 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, SA299 Gr.B steel plate is required to have a higher medium temperature, outstanding shaping and heat treatment process functions, and outstanding welding functions.
 

Main features of SA299 Gr.B plate

Mechanical function: strength, hardness, plasticity, fatigue and impact toughness of SA-299MGr.B steel plate are guaranteed.
Chemical function: corrosion resistance, high temperature oxidation, the raw materials of SA299 Gr.B steel are guaranteed, and the chemical composition can be tested and used.
Physical functions: density, melting point, thermal expansion, magnetism, electrical conductivity. SA299 Gr.B plate can be guaranteed under special conditions.
Process function: cutting function, forgeability, castability, weldability. SA-299MGr.B process function can carry out spot cutting
 
Delivery status: Delivery status: hot rolling, normalizing, stress relief treatment. Generally, the SA299 Gr.B plate thickness is more than 50mm and delivered under normalizing condition. The SA299 Gr.B steel plate produced by Katalor Industry can guarantee the function and the raw material, and generally requires normalized delivery. The company can provide steel plates with flaw detection requirements, Z15-Z35 thickness direction functional requirements, high strength and high toughness requirements.
