JIS G3114 SMA400BW Weathering Steel

 

 

 

 

 

JIS G3114 SMA400BW represents a specialized category within Japanese weathering steels that prioritizes enhanced toughness alongside atmospheric corrosion resistance. The "B" classification specifically denotes guaranteed impact toughness properties, setting it apart from standard grades by ensuring reliable performance under dynamic loading and in lower temperature environments. With a minimum tensile strength of 400 MPa, this steel maintains the fundamental weathering mechanism through its copper-chromium-phosphorus alloy system while incorporating precise metallurgical controls to achieve superior fracture resistance.
