ASTM A268 Welded Stainless Steel Tubing

The ASTM A268 standard specification applies to both seamless and welded ferritic and martensitic stainless steel pipes for general use. This standard covers various grades of nominal wall thickness, primarily for stainless steel pipes intended for general corrosion resistance and high-temperature service.

ASTM A268 applies to the following types of stainless steel pipes:

Seamless and welded ferritic and martensitic stainless steel pipes: These pipes, commonly referred to as "straight chromium" types, are ferromagnetic and can be hardened through heat treatment. Ferritic alloys with high chromium content are sensitive to notch brittleness when slowly cooled to room temperature.

The ASTM A268 standard includes a range of ferritic and martensitic stainless steel grades, such as TP405, TP410, TP429, TP430, TP443, TP446-1, TP446-2, TP409, TP439, S41500, S44400, S44700, S44635, and TP468.
