SS304 contains 18% chromium and 8% nickel. SS316 contains 16% chromium, 10% nickel and 2% molybdenum. The "moly" is added to help resist corrosion to chlorides (like sea water and de-icing salts) .
they are both the same. same grade of metal. the name is different tho because sus304 is the american term and t304 the japanesse term.
ss 316 has more nickel content than ss 304, which improves its corrosion resistance, especially ss 316 is more resistance to piting corrosion by chloride ion
Type 316 is an austenitic chromiumnickel stainless steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Properties are similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides.
First of all, a stainless steel is a steel that has > 10.5% Chromium (Cr); this ensures development of a chrome-oxide that prevents further oxidation. The 300 series of stainless steels differs from the 400 series in that the 300 series has both Cr and Nickel (Ni) - the 400 series has only Cr. 304 stainless steel has 18% Cr & 8% Ni. 316 stainless steel has 16% Cr, 10% Ni, & 2% Molybdenum (Mo). I believe this added Mo increases corrosion protection from chrloride-induced corrosion.
Completely isolate the electrical circuit - so use some insulation such as PVC to ensure the metals are not in contact - but the above situation should not be allowed in the first place - very poor design indeed.
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst theaustenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Grade 316L, the low carbon version of 316, is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. EnduraMet(R) 316LN stainless is a nitrogen-strengthened version of Type 316L stainless. By means of solid solution strengthening, the nitrogen provides significantly higher yield and tensile strength as annealed than Type 316L without adversely affecting ductility, corrosion resistance or non-magnetic properties. In the hot rolled unannealed condition, yield strength of 75 ksi (518 MPa) or higher can be achieved for bar diameters up to 1.375in (34.925mm). The foregoing information was gathered from two different web locations arrived at by searching for "stainless steel rebar" and "316LN stainless steel." It appears that Type 316 is a standard stainless steel, 316L is a low carbon stainless steel, and 316LN is a low carbon nitrogen strengthened stainless steel.
UTS of 304L Stainless Steel is 586MPa UTS of 304 Stainless Steel is 621MPa
304 and 304L are stainless steel electrodes. but in 304L, L denotes Lower percentage of Carbon content.It improves the corrosion resistance character of filler wire.
Compared to 304 grade stainless steel, the 316 has higher strength, can withstand higher temperatures, and yes it can resist corrosion better. One factor is the molybdenum content in the 316 grade which gives it the overall corrosion resistant properties. The downside, 316 stainless steel grade is way more expensive than 304.
s.s 304 is the best material for heat resistance i.e its has good properties axydisation , not acidic reactive

Nothing there both the same

the answer is 304
Type 316 is an austenitic chromiumnickel stainless steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Properties are similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides.
A stainless steel corrosion resistant variety contains more than 10% chromium along with possible other alloying elements. Corrosion attacks in stainless steel are resisted by weak mineral and acids and it is able to keep its strength at high temperatures. The most common grades are 304, 316, and 409.

The 200-series stainless steel is of lower quality compared to the 300-series. 200-series uses lesser chromium and nickel and are therefore less corrosion resistance. 200-series is most commonly found in India kitchenware.

Annealing. Heat from 1010oC to 1120oC and cool rapidly in air or water. The best corrosion resistance is obtained when the final annealing is above 1070oC and cooling is rapid.
