Stainless steel parts contain at least 50% iron and 10% chromium. Generally speaking, the more chromium, the greater the corrosion resistance. The simple answer about the difference between two grades is that 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).

304 Stainless Steel Ball Valve

304 stainless steel valve, with its chromium-nickel substance and low carbon, is the most flexible and broadly utilized of the austenitic stainless steels. Its compounds are all adjustments of the 18% chromium, 8% nickel composite. Sort 304 turns out to be impervious to oxidation, consumption, and toughness. All give simplicity of creation and cleaning, avoidance of item tainting offer an assortment of completions and appearances. Sort 304 stainless steels are utilized within ventilation systems, stainless fittings, stockpiling tanks, weight vessels and funneling.

316 Stainless Steel Ball Valve

316 stainless steel valves is an authenticate chromium-nickel stainless and high temperature opposing steel with better consumption safety as looked at than other chromium-nickel steels when presented to numerous sorts of concoction erosion bringing on components, for example, ocean water, saline solution results, and so forth. Since Type 316 stainless steel amalgam holds molybdenum bearing it has a more prominent imperviousness to concoction assault than 304. Sort 316 is strong, simple to-create, clean, weld and completion. It is extensively more impervious to results of sulphuric corrosive, chlorides, bromides, iodides and unsaturated fats at high temperature.

While you can use stainless steel 304 vs 316, the SS316 parts are made to last longer in adverse conditions. Staineless Steel 304 parts cost less, but may have a shorter lifespan in some conditions.
