1.Application Potential:
A285/A285M specification covers carbon steel plates of low-and intermediate-tensile strengths which may be made by killed, semi-killed, capped, or rimmed steel practices at the producer’s option.This standard covers steel A285GrA,A285GrB and A285GrC.These plates are intended for fusion-welded pressure vessels.They are widely used in the fabrication of boilers in industries such as shipbuilding, petrochemical and manufacturing.
