Accreditation Administration System:
A588/A588M
Atmospheric corrosion resistance steel plates A588GrB under specification
A588/A588M.According to the contains of P and S chenical elements in these steel plates and coils,when
properly exposed to the atmosphere,this steel is suitable for many applications in the bare and unpainted.
For this details,you can check the Guide G101 standard.The relative other grades are A588GrA,A588GrC
and A588GrK
The Heat Analysis and tension test specimens both shall conform to the requiements as to the values in
the below table.
