KF25/NW25 premium grade 316L stainless steel angle flange with alumimum valve for ultra durability, great for all sorts of high vacuum operations.
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic 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 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). 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. 316L are used to avoid corrosion problems caused by welding.
316L grade has the following characteristics:
- Higher creep resistance
- Excellent formability
- Rupture and tensile strength at high temperatures
- Corrosion and pitting resistance
