Type 304 stainless steel is considered to resist pitting and crevice corrosion in waters containing up to about 100 ppm chloride.
S steel 316l bransoletka.
For elevated temperature applications the high carbon variant 316h stainless steel and the stabilised grade 316ti stainless steel should be employed.
316 316l stainless steel pipe 316 316l stainless steel pipe these grades of austenitic stainless steels are similar to 304 and 304l but with the addition of molybdenum.
316l stainless steel can be hot worked using the most common hot working.

This makes it suited to use in heavy gauge over about 6mm welded components.
Heavy welded sections in grade 316 require post weld annealing for maximum corrosion resistance.
Steel type 316 316l can be conveniently welded and processed through standard fabrication methods.
And 316l show similar performance.
316l stainless steel is also easier to machine compared to 316 stainless steel due to its lower carbon content.
Hot and cold working.
The addition of molybdenum gives it a better corrosion resistance than other austenitic stainless steel grades such as 304.
Excellent weldability by all standard fusion methods both with and without filler metals.
Stainless steel grade 316 grade 316 316l technical data summary.
As 1554 6 pre qualifies welding of 316 with grade 316 and 316l with grade 316l rods or electrodes or their high silicon equivalents.
316 316l stainless steel type 316 is widely used in applications requiring corrosion resistance superior to type 304 or good elevated temperature strength.
Grade 316 is an improved version of cs 304 with the addition of molybdenum and a slightly higher nickel content.
But to avoid intergranular corrosion attack of welds and heat affected zone alloy 316l should be utilized that has lower content of carbon.
This is not required.
316l stainless steel tends to work harden if machined too quickly.
The resultant composition of cs 316 gives the steel much increased corrosion resistance in many aggressive environments.
For this reason low speeds and constant feed rates are recommended.
The pre n of type 316 and 316l 24 2 is better than that of type 304 pre n 19 0 reflecting the better pitting resistance which type 316 or 316l offers due to its mo content.
Typical uses include exhaust manifolds furnace parts heat exchangers jet engine parts pharmaceutical and photographic equipment valve and pump trim chemical equipment.
