Stainless Steel pipe fittings 316 pipe bend with excellent forming and welding characteristics
316 pipe bend contains a minimum 2.0% molybdenum which makes it much more corrosion resistant than 304 however, as it is a more expensive element, generally makes 316 a more expensive grade of metal.
1.4404 is the numeric designation for the 316 / 316L grade of austenitic stainless steel according to the European Standard, where for the exact designation of the material, experts use this option (as for other grades, designations such as 1.4301, 1.4571 or 1.4404 are preferred). Type 316 (UNS 31600) is an austenitic chromium-nickel stainless steel alloy containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions and provides increased strength at elevated temperatures. The inox grade AISI 316 / AISI 316L usually contains between 10 and 13 wt% of nickel, which makes this steel basically non-magnetic. Due to its lower carbon content, AISI 316L / 1.4404 is however easier to machine and to weld than the otherwise equivalent stainless steel AISI 316 / 1.4401.
