316 Stainless Steel

316 stainless steel stockholders and suppliers. 316 is an austenitic grade which is suitable for use in severely corrosive conditions available for delivery to the whole of the UK. It is classed as a chromium nickel molybdenum stainless steel grade. The addition of molybdenum gives it a better corrosion resistance than other austenitic stainless steel grades such as 304. It achieves a higher resistance to pitting and crevice corrosion in a chloride environment. The 316L grade has a reduced carbon content to improve corrosion resistance after welding.

316 stainless steel grade is more resistant to atmospheric and other mild types of corrosion than that of other austenitic stainless steel grades, such as 303, 304, 321 and 310. As a molybdenum bearing stainless it is considerably more resistant to solutions of sulphuric acid and phosphoric acid than that of other austenitic grades. 316 has a better resistance to pitting corrosion and stress corrosion cracking in chloride solutions to that of other non molybdenum bearing stainless steel grades.

Stainless steel 316 is readily weldeable with most welding procedures. Oxyacetylene welding is not recommended due to possible carbon pick up in the weld area. With its lower carbon content 316L stainless is preferred to standard 316 as it can be welded without loss of corrosion resistance due to intergranular carbide precipitation. Post weld annealing is not normally required, except for service in more extreme conditions. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding stainless steel.

Heat the 316 slowly and uniformly throughout the section to 1150-1200°C. Re heat as necessary and avoid working below 900°C. Cool in air. Forgings will require annealing in order to obtain optimum corrosion resistance.

The oxidation resistance of a stainless steel specification is traditionally termed as the scaling temperature. This is the temperature at which the oxidation rate of a stainless steel becomes unacceptably high. The safe scaling temperature for continuous service of 316 is 875°C. In an oxidising and reducing sulphurous atmosphere the scaling temperature of 316 stainless is lowered.
