B4B Round Bars ASTM A437/A437M

Description

B4B Round Bars

B4B Round Bars is a hardenable stainless steel designed for use at temperatures of up to 1200ºF (649ºC). B4B Grade has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. B4B Round Bar is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting etc. With the right heat treatment, parts made of this steel can also have excellent mechanical properties depending on section, form, and application involved.

ASTM A437 B4B Round Bar also has good resistance to scaling and oxidation and excellent creep-rupture properties at temperatures up to 1200°F (649°C). Among similar high alloy steels with martensitic structure, B4B Grade has the highest electrical conductivity and a moderately high embodied cost. B4B Round Bar also has better strength at a higher temperature than the somewhat similar other Steel.

This alloy is mainly used for manufacturing of buckets and blades for steam turbines, but also in the aerospace industry for manufacturing of high temperature bolting, valves and valve trim. Other less common applications of Stainless Steel B4B are in refineries, thermal pipe plants, pharmaceutical industry, oil refineries, textile industries, nuclear plants, chemical industry, etc

ASTM A437 / A437M is a Standard Specification for Stainless and Alloy-Steel Turbine-Type Bolting Specially Heat Treated for High-Temperature Service. Other Grades under this standard are B4D .
