Comparison of ASTM Specifications and Similar Standars

Materials specifications for Butt-welding fittings ASTM Materials

Asterisks(*) denote that the carbon content shall be 0.04 to 0.10% Daggers(+) denote that the minimum tensile
strength shall be 65,000 psi (488 Mpa, and that the minimum yield strength shall be 25,000 psi (172Mpa)

The yield strength shall be determined by thd offset method at 0.2% limiting permanent set in accordance with ASTM
A370 Specification, An alternative method of determining yield strength may be based on a total extension under load 0.5%

The basic minimum elongation for wall 3/16(7.94mm) and over in thickness shall be determine accoding to strip tests:
all small sizes are tested in their full section.

P and PL denote Pipe and Plate respectively.
