    PRODUCT DESCRIPTION

    ASTM A312 UNS S31254 STAINLESS STEEL WELDED PIPES, ASTM A312 SMO 254 STAINLESS STEEL seamless PIPES, ASTM A312 1.4547 STAINLESS STEEL WELDED PIPES, uns s31254 STAINLESS STEEL WELDED PIPES supplier, ASTM A312 ALLOY 254 STAINLESS STEEL WELDED PIPES, ASTM A269 254SMO stainless steel tubes factory in China HT PIPE.

    254SMO stainless steel is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion.
