Comparison of 316, 316L & 316Ti Stainless Steel Types

Grade 1.4571 (316Ti or 320S31), is essentially a standard carbon 316 type with titanium stabilisation and is similar in principle to the titanium stabilisation of the 304 (1.4301) type to produce 321 (1.4541). The role of the titanium alloy addition is discussed and is compared with the alternative low carbon 316 types. Comparisons of elevated temperature mechanical strength, pitting corrosion resistance, mechanical polishing and weldability are also made.
