Before Getting to know about slip-on flange Grades let us first understand what is a slip-on flange.
Slip-on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of the slip-on flange is also welded on the backside of the flange.

310 Stainless Steel Slip On Flanges

Stainless Steel Slip-on Flanges Grades Designed for high-temperature applications, 310 stainless steel slip-on flanges provide high-temperature oxidation resistance to 2000°F under mildly cyclic conditions. An economic alternative to nickel alloys like alloy 330 or Inconel, 310 flanges provide slightly less strength and temperature resistance but at a significantly lower price point. Alloy 310 can be used in moderately carburizing, moderately oxidizing, nitriding, cementing, and thermal cycling applications when not used at the maximum service temperature. 310SS slip-on flanges also have good resistance to sulfidation and other forms of hot corrosion. Although primarily known for its high-temperature ...
... properties, 310 stainless steel also provides excellent performance at cryogenic temperatures, with toughness down to -450˚F. Though 310 slip-on flanges are ideal for high-temperature use, they should not be exposed to the severe thermal shock of repeated liquid quenching or where aqueous corrosive contaminants are present.
