316 stainless steel flat and 316 stainless steel flat is a chromium-nickel-molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304 / 304L in moderately corrosive environments. SS 316L Stainless Steel flat is more corrosion resistant than SS 316 and any other related common alloys.
Properties
316 SS flat and SS 316 flat have good corrosion resistance to pitting in phosphoric and acetic acid solution. It performs well in boiling 20% phosphoric acid. The alloy can also be used in the food and pharmaceutical process industries where it is utilized to handle hot organic and fatty acids in an effort to minimize product contamination.

SS 316L, the low carbon version of 316 stainless steel, is immune to grain boundary carbide precipitation (sensitisation). This makes it suited to use in heavy gauge (over about 6mm) welded components. For elevated temperature applications the high carbon variant, 316H stainless steel and the stabilised grade 316Ti stainless steel should be employed.

316 stainless flat is widely used in environments where sulphur dioxide gas is present at high temperatures. The alloy does not perform in reducing, nitriding or carburizing atmospheres, but it does outperform most heat resistant stainless steels in these conditions.
Application
Stainless Steel 316 flats offer a wide range of applications. High Chromium with additions of Molybdenum can be used for these Stainless Steel 316 flats in quite aggressive conditions such as sea water. Stainless Steel 316 flats are also chosen for their resistance to stress corrosion cracking, which are further not as formable as austenitic stainless steels.
Stainless Steel 316 flat is often used in biomedical implants, chemical processing, pharmaceutical, textile finishing, food processing, photographic, marine exterior trim, Pulp & Paper Industry, Aerospace Industry, Oil and Gas Industry etc.
Shalco Industries is a manufacturing company of Flat in India and Global Supplier.
