Grades 1.4401 and 1.4404, commonly known as stainless steel grades 316 and 316L, are the second most commonly used stainless steel grade after 304/304L. 316 is basically an improved version of 304, with addition of molybdenum and slightly higher content of nickel.
However, both 304 and 316 grades have significant commercial usage due to their good corrosion resistant properties, crevice corrosion and cost effectiveness. Stainless steel 316 contains an addition of molybdenum that gives it improved corrosion resistance, particularly in chloride environments.
316L, the low carbon version of Stainless steel 316, while Type 316H is a higher carbon variant of 316 mainly suitable for elevated temperature applications. 316Ti is a titanium stabilized version of 316. Resistance to sensitization is achieved in type 316Ti with titanium additions to stabilize the structure against chromium carbide precipitation, which is the source of sensitization.
Given the good forming and welding characteristics, 316L grade stainless steel flanges and pipes are widely used in marine, petrochemical, power generation and external architectural applications.
wilsonpipeline is a leading manufacturer and supplier of stainless steel grade 316 tube, pipe, fittings, flanges, bars, fasteners, castings and others.
316/316L stainless steel pipes, stainless steel flanges and stainless steel fittings are widely used in the manufacture of food processing equipment, brewery equipment, chemical and petrochemical equipment, coastal architectural paneling, coastal balustrading, boat fittings, chemical transportation containers and heat exchangers.
