Differences Between 304 & 316 Stainless Steel Fasteners and Application Guide

Differences Between 304 & 316 Stainless Steel Fasteners and Application Guide

304 and 316 stainless steel differ greatly in molybdenum content and anti-corrosion property.

1. Material composition gap

316 contains molybdenum for better chloride corrosion resistance while 304 has no molybdenum.

2. Different applicable occasions

304 for inland machinery;316 for coastal,chemical and seawater related equipment.

3. Identification methods

Reagent test and salt spray experiment are reliable ways to check material grade.
