Stainless Steel
316 Stainless Steel
Molybdenum addition over 304 gives better resistance to chlorides and industrial corrosion. Common in marine and chemical processing environments.

Buying This Grade in Pakistan
Sold into chemical processing, pharmaceutical, and marine fitting fabrication in Karachi's industrial areas, chosen over 304 specifically where chloride exposure or stricter corrosion resistance is a requirement. A narrower, more technical buyer than the general stainless steel trade.
