321 Stainless Steel for Chemical & Refinery Equipment
Type 321 stainless steel occupies a specific position in chemical, petrochemical and petroleum-refining equipment: it is selected primarily when welded austenitic stainless steel must retain resistance to intergranular corrosion during elevated-temperature exposure. Its key feature is titanium stabilization rather than molybdenum alloying. That distinction matters because Type 321 solves a different engineering problem from Type […]
316L Stainless Steel for Chemical & Refinery Equipment
316L stainless steel is one of the most important molybdenum-alloyed austenitic stainless steels used in chemical and petrochemical processing equipment. Compared with 304L, the addition of molybdenum gives 316L a greater margin against pitting and crevice corrosion in many chloride-containing and chemically demanding environments. Its low carbon content also makes it particularly useful for welded […]
