ASTM A53发表评论(0)编辑词条

ASTM A53 is a carbon steel alloy, used for structural steel pipe. The alloy specifications are set by ASTM International, in specification ASTM A53/A53M[1]. A53 pipe is suitable for structural or pressure applications.

A53 pipe comes in three types and two grades, A53 Type F, which is longitudinally furnace butt welded or continuous welded (Grade A only), A53 Type E, which is longitudinally electric resistance welded (Grades A and B), and A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel (Grades A and B).

Specifications

As with other steels, A53 has a specific gravity of approximately 7.85, and therefore a density of approximately 7850 kg/m3.

A53 pipe comes in two grades, A and B. Grade A is not commonly used for structural applications.

A53 Grade A has a minimum tensile yield strength of 205 MPa (30 ksi), and minimum tensile ultimate strength of 330 MPa (48 ksi). A53 Grade B has a minimum tensile yield strength of 240 MPa (35 ksi), and minimum tensile ultimate strength of 415 MPa (60 ksi).
