ASME SA53 grade B steel pipe can be seamless and welded black and hot-dipped galvanized steel pipe. SA53 grade B can be shorten as SA53 Gr B or SA53B. ASME SA53 grade B steel pipe covers 2 types: one is "Type E" - Electric-resistance welded pipe / ERW pipe; the other is "Type S" - seamless pipe / SMLS pipe. Type S ASME SA53 grade B steel pipe SA53 Gr B seamless pipes are more widely used than SA53 grade A seamless pipes.

Type S ASME SA53 grade B steel pipe SA53 Gr B seamless pipes chemical composition:

Type S ASME SA53 grade B steel pipe SA53 Gr B seamless pipes mechanical properties:

Type S ASME SA53 grade B steel pipe SA53 Gr B seamless pipes shall be made by one or more of the processes: open-hearth, electric-furace, or basic-oxygen. They are intended for mechanical and pressure applications. Type S ASME SA53 grade B steel pipe is also acceptable for ordinary uses in steam, water, gas, and air lines.
