Grade 316 Stainless Steel

Approximate Composition – 17% chromium, 10% nickel, 2% molybdenum (exact composition ranges vary between EN and ASTM standards).

Molybdenum enhances the corrosion resistance of stainless steel even in relatively small amounts. 1% of molybdenum is worth about 3% of chromium in terms of corrosion resistance.

In environments where 304 (1.4301) is found to be inadequate (i.e. due to harsh cleaning chemicals), 316 (1.4401) is the natural first grade to be considered.

Materials should always be assessed against individual requirements and risk assessments before being introduced to a cleanroom.
