Q:What is 316L stainless steel?

316L (UNS S31603) is a low-carbon austenitic stainless steel with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, offering superior corrosion resistance and excellent weldability.

Q:Why is 316L preferred over 304 for gas processing?

316L contains 2-3% molybdenum, providing superior resistance to pitting and crevice corrosion from chlorides and corrosive gases, and its low carbon content prevents sensitization during welding.

Q:Is 316L suitable for sour gas (H2S) applications?

Yes - 316L is listed in NACE MR0175/ISO 15156 for sour gas service. Please specify your NACE requirement when inquiring.

Q:What is the maximum part size you can machine?

1500mm x 500mm x 500mm - suitable for large valve bodies, flanges, and custom components.
