A500 GRA GRB GRC GRD structural pipes are carbon steel cold-formed round and special-section welded steel pipes and seamless steel pipes. The A500 standard has strict requirements on tensile strength, yield strength and chemical element content. All A500 steel pipes can be delivered only if the chemical element content and mechanical properties are qualified:
A500 GRA requires a maximum carbon content of 0.30%, a maximum manganese content of 1.40%, a tensile strength of ≥310Mpa, and a yield strength of ≥230Mpa.
A500 GRB requires a maximum carbon content of 0.30%, a maximum manganese content of 1.40%, a tensile strength of ≥400Mpa, and a yield strength of ≥290Mpa.
A500 GRD requires a maximum carbon content of 0.30%, a maximum manganese content of 1.40%, a tensile strength of ≥425Mpa, and a yield strength of ≥415Mpa.
A500 GRC requires a maximum carbon content of 0.27%, a maximum Mn content of 1.40%, a tensile strength of ≥400Mpa, and a yield strength of ≥250Mpa.
