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.
