What is SS 316? Difference Between SS 304, SS 316 and SS 316L

Stainless Steel 316 is a chromium-nickel based, molybdenum-bearing austenitic stainless steel that possesses increased levels of resistance against several substances, due to the addition of molybdenum in its composition to help resist corrosion to chlorides (like sea water and de-icing salts). Grade 316 is an improved version of SS 304 because of slightly higher molybdenum and nickel content. The molybdenum allows SS 316 to be more resistance to corrosion overall in many aggressive environments, with specific resistance against chlorine pitting and crevice corrosion in chloride environments. SS 316 is also found to be more applicable in areas with high or elevated temperatures compared to other stainless steels. It has more heat resistance than Type 304 but otherwise possesses many of the same general characteristics.
316’s corrosion resistance is especially effective against chemicals, such as those used in the paper and textile industries. The metal finds other common applications in food processing equipment, chemical processing, nuts and bolts, and medical implants. While the metal is pliable under hot and cold-working techniques, it cannot be work hardened with heat treatment and in general is considered to have lower weldability compared to the 304 type stainless steels. However, it is still preferred over many other stainless steel grades in terms of workability.

Austenitic stainless steels can be welded together using many different welding processes. Some are more preferred for welding than others, such as 304, 308, 316, 321, and 347 which are all austenitic grades that are weldable.

The difference between 304 and 316 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). The difference between 316 and 316L stainless steel is that 316L has a .03 max carbon and is good for welding whereas 316 has a mid range level of carbon. Even greater corrosion resistance is delivered by 317L, in which molybdenum content increases to 3 to 4% from the 2 to 3% found in 316 and 316L.

What is the Price for 316/316 Seamless & Welded Pipes in Kolkata?

The prices for stainless steel 316 pipes is different for welded and seamless type. Welded 316 stainless steel pipes are mainly manufactured in India, are available at very lower price compared to seamless pipes. 316 stainless steel seamless pipes are high cost pipes, due to higher cost of production and import duties.

Stainless steels are defined as ferrous alloys with the addition of at least 10.5% chromium by weight and are essentially low carbon steels containing significant amounts of chromium. It is the addition of chromium that gives this type of steel its corrosion resisting properties.

The chromium content of the steel allows the formation of an invisible corrosion resistant chromium oxide film on the steel surface. If damaged mechanically or chemically this film is self-healing providing that oxygen, even in very small amounts, is present. The corrosion resistance of stainless steel can be enhanced along with providing other useful properties by increasing the chromium content and by adding other elements such as molybdenum, nickel, and nitrogen.

Kolkata also known as Calcutta is home to many industrial units operated by large public- and private-sector corporations; major sectors include steel, heavy engineering, mining, minerals, cement, pharmaceuticals, food processing, agriculture, electronics, textiles, and jute.
