ASTM A738/A738M-19(2026)

Annotation of standard text ASTM A738/A738M-19(2026) :

This specification covers heat-treated carbon-manganese-silicon steel plates intended for use in welded pressure vessels at moderate and lower temperature service. The materials are available in four strength levels and five grades, namely Grades A, B, C, D, and E. The maximum thickness of plates is limited only by the capacity of the chemical composition and heat treatment to meet the specified mechanical property requirements. The steel shall be killed and the plates shall be subjected to heat treatment, quenching, and tempering. The plates shall undergo a tension test to determine mechanical properties such as tensile strength, yield strength and elongation.
