Stainless Steel 904L Pipes & Tubes

ASME SB677 Stainless Steel 904L Seamless Pipe, Inox 904L Pipe, ASTM A249 / ASME SA249 Stainless Steel 904L Welded Tubes, ASTM A358 / ASME SA358 Stainless Steel & 904L EFW Pipes Manufacturers, Supplier.

Alternate grades that are possibly used :

SS 316L Pipes, because it’s a lower price option, but in the company of much inferior corrosion resistance. Also, SS 6Mo Pipes, as a superior resistance to crevice corrosion and pitting is required. In addition, as well Duplex UNS32205 Pipes, as it’s having superior mechanical potency, and at a lower price to 904L.

904L Stainless Steel Properties :

ASME SB677 Grade 904L stainless steels have exceptional resistance to chloride attack and warm seawater. 904L Tubing offer excellent oxidation resistance. Grade 904L SS Pipes can be solution heat-treated at 1090 Degree C to 1175 Degree C, after rapid cooling. Welding of Grade 904L SS Tubes can be carried out using all conventional procedures. Also referred as UNS NO8904 Pipes, they are high purity steels by means of low content in sulphur. These 904l stainless pipes can also be machined by using any normal ways. 904l stainless tubes does not need post-weld and pre-heat heat conducts. One more quality of ASTM B677 SS 904L is that it can be imperiled to hot cracking in controlled weldment. Meanwhile, thermal treatment is suitable for hardening these grades. On the other hand, the structural constancy of stainless steel 904L collapses at soaring temperatures, mainly beyond 400 Degree C. This UNS NO8904 Tubes needs to be solution canned after cold working, for to attain maximum SCC resistance under severe atmospheres.
