HEAT EXCHANGER TUBE ASTM A213 TP316L STAINLESS STEEL SEAMLESS TUBE
Overview
Grade 316 Stainless Steel Tubes or UNS S31600 Tubes are one of the
most common grades of stainless steel offers good strength and heat
resistant and oxidation resistance properties in continuous
temperature service. The key properties of this material are its
high chromium and medium nickel content making its resistance to
oxidation, sulfidation and other forms of hot corrosion its main
characteristics.
Grade 316 is the standard molybdenum-bearing grade, second in
importance to 304 amongst the austenitic stainless steels. The
molybdenum gives 316 better overall corrosion resistant properties
than Grade 304, particularly higher resistance to pitting and
crevice corrosion in chloride environments. It has excellent
forming and welding characteristics. It is readily brake or roll
formed into a variety of parts for applications in the industrial,
architectural, and transportation fields.
Grade 316L, the low carbon version of 316 and is immune from
sensitisation (grain boundary carbide precipitation). Thus it is
extensively used in heavy gauge welded components (over about 6mm).
