Stainless Steel 316 / 316H / 316L Flange

Duplex Steel & Alloys manufactures and supplies high-quality Stainless Steel 316 Flanges to our clients using cutting-edge technology and high-quality raw materials. We have a professional staff that oversees the quality assurance of these flanges.

After grade SS 304, Stainless Steel 316L Flanges are the next most used stainless steel grade, both of which are from the austenitic stainless steel family, whose structure provides them with outstanding toughness across a wide temperature range, including cryogenic temperatures. The main chemical components of the alloy are chromium, nickel, and molybdenum. The addition of molybdenum improves the alloy's corrosion resistance over SS 304, notably in chloride environments.

Stainless Steel 316 Flanges

Stainless Steel 316H Flanges are available and have two modified versions, mainly 316L and 316H. The naming system depends on the carbon concentration of each grade. The carbon content of stainless steel 316L is restricted to 0.03 percent while 316H, on the other hand, has a carbon content ranging from 0.04 percent to 0.1 percent, as well as the absence of nitrogen from the mixture. SS 316 is suitable for intermittent service up to 1598°F and continuous service up to 1697°F. If water corrosion resistance is necessary, these tubes should not be utilized at temperatures ranging from 425-860°C.

What is the difference between Stainless steel 316L/316H Flanges and that of SS 316?
Stainless steel 316L flanges have better resistance to the carbide precipitates than the 316 grade that forms on the grain boundary. It is also more resistant to intergranular corrosion. In regards to corrosion resistance, there is very little difference between 316 and 316L. Because high carbon content provides higher tensile and yield strength, stainless steel 316H Flanges allow them to be utilized at higher temperatures. Because of its increased temperature strength, Grade 316H is occasionally used in structural and pressure-containing systems at temperatures over 500°C.
