Steel pipe grades chart

tensile, yield strength and chemical composition by API 5L and ISO 3183

Tables for two basic levels of standard technical requirements for line pipe. Product specification levels PSL1 (standard quality) and PSL2 (additional mandatory requirements).

Delivery conditions available are: R (As-rolled), N (normalized), Q (quenched and tempered) or M (thermo-mechanical rolled or thermo-mechanical formed).

Both unit systems are available: International System (SI) units and United States Customary (USC) units.
