A specification for stainless steel with chromium and molybdenum in its alloy is stainless steel 316. The Stainless Steel 316 Flanges are frequently utilised in situations vulnerable to chloride ion corrosion because of their distinctive composition. The molybdenum addition makes the stainless steel 316 material extremely corrosion resistant, particularly in chloride-rich environments.

The 316-grade material is available in both wide and low-carbon varieties. The toughness of the planned use and the welding requirements determine which one is best. In various industrial applications, including food processing, maritime, structural, construction, pharmaceutical, and many more, stainless steel 316 flanges are frequently employed.

There are various 316 Flange kinds available, including blind, slip-on, weld neck, socket weld, and orifice type flanges. Each has a unique shape, and they serve a variety of functions. These flanges can be attached to the piping connections using bolts and nuts, various welding techniques, or a combination of the two.

The low carbon variant of the stainless steel 316-grade material is known as stainless steel 316L. Along with steel grades 304, 304L, and 316, it is one of the most used worldwide. Molybdenum is a component of the alloy that gives the stainless steel 316L flanges more corrosion resistance than the 304-grade flanges.

What is the distinction between Stainless Steel 316 and Stainless Steel 316L?
The main distinction between 316 and 316L stainless steel is the carbon content. While 316 has a maximum carbon content of 0.08%, 316L has no limit.

What makes 316L flanges superior to 316 flanges?
316L stainless steel is nearly comparable to 316 stainless steel. The sole distinction is the carbon content. Because of its decreased carbon content, 316L has even superior corrosion resistance than 316. Post-weld annealing is not required with 316L.

Are stainless steel 316L flanges waterproof?
The 316L grade is nickel, lead, and cadmium free. Furthermore, the original hue of stainless steel (silver) is water-resistant and does not tarnish.

How many types of SS 316, 316L Flanges?
Weld neck Flanges (WNRF), Slip-on Flanges (SORF), Blind Flanges (BLRF), Lap Joint Flanges (SOLJ), Socket-weld Flanges (SWRF), Screwed (Threaded) Flanges, Long weld neck Flanges (LWNRF), Spectacle Blind Flanges, Spacer & Blind Flanges, Ring Type Joint Flanges (RTJ), Reducing Flanges, Raised
