Compare SS 304, SS 316 and SS 316L for industrial procurement, pharma, food, marine, fabrication and RFQ preparation.
SS 304 is commonly reviewed for general fabrication and equipment work, SS 316 adds molybdenum for improved chloride resistance, and SS 316L is reviewed when lower carbon content is specified for welded or corrosion-sensitive fabrication. Final selection should follow buyer drawings, standards, service conditions and project requirements.
| Option | Common buyer review context | RFQ note |
|---|---|---|
| SS 304 | General fabrication, food equipment, tanks and panels | Share size, finish and fabrication route. |
| SS 316 | Marine, chemical, chloride and process environments | Mention chloride exposure and operating condition. |
| SS 316L | Welded pharma, food, process and corrosion-sensitive work | Share welding, MTC and inspection requirements where applicable. |
