316LN (UNS S31653) is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. The nitrogen in Type 316LN adds additional resistance to sensitization in some circumstances. The nitrogen content of Type 316LN stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to Type 316L stainless steel. Like Types 316 and 316L, the Type 316LN alloy also offers good resistance to general corrosion and pitting/crevice corrosion. Please note that we have a minimum order value of £10,000.

316Ti (UNS S31635) is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. High carbon Alloy 316 stainless steel can be susceptible to sensitisation, the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500°F (425 to 815°C) which can result in intergranular corrosion. Resistance to sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the structure against chromium carbide precipitation, which is the source of sensitisation. This stabilisation is achieved by an intermediate temperature heat treatment, during which the titanium reacts with carbon to form titanium carbides. Please note that we have a minimum order value of £10,000.

Surgical Implant 316L is a double melted stainless steel, regarded as a medical grade, this stainless steel is melted to achieve high levels of purity and cleanliness. It has excellent resistance to both general and intergranular corrosion, and pitting and crevice corrosion. The double melting allows for superior surface finish. Surgical implant 316L Stainless Steel is our most commonly sold medical stainless steel. Beyond removing impurities, this process, in combination with the unique nickel and chromium content of 316, tends to facilitate the formation of the surface chromium oxide layer that makes stainless steel corrosion resistant. There is some belief that surgical implant 316L forms a more substantial surface layer, and that this plays a strong role in protecting the host body from reactions to the nickel content of the material. Please note that we have a minimum order value of £10,000.
