รายละเอียดเอกสาร

This specification is intended for high-strength, low-alloy forged rings and hollows produced from steels with atmospheric corrosion resistance for use as base plates in welded tubular structures. These steels have considerably better atmospheric corrosion resistance in most environments than carbon structural steel with or without copper addition, and are suitable for many applications in the bare (unpainted) condition when exposed to the atmosphere. The standard covers ordering information and general requirements for delivery, materials and manufacture, heat treatment, mechanical requirements, and the material's chemical composition.
