Material profiles

Stainless steel 304 vs 316: differences and sourcing

Austenitic grade 304 offers general-purpose corrosion resistance, while 316 with 2–3% molybdenum is far more resistant in chloride environments (seawater, chemicals). Surface finish (2B, BA, No.4), thickness and the nickel-linked alloy surcharge drive cost.
