Grade 317 or UNS S31700 is an austenitic stainless steel. This alloy is an improved version of grade 316 stainless steel, and with this in mind, ASTM A182 F317 flanges are compared to molybdenum-containing alloys because there is significantly more molybdenum added to the alloy compared to grade 316. will be called. Molybdenum is an alloying agent added to chromium-nickel based austenitic stainless steel parts, such as ASTM A182 F317 slip-on flanges, and is known to improve the alloy's resistance to pitting as well as crevice corrosion. I am. Pitting and crevice corrosion resistance are properties found in Grade 317 flanges when exposed to environments containing chlorides, sulfur, and halides.
The 317 stainless steel flange is resistant to sulfuric acid, with solution concentrations up to 5 percent at temperatures up to 120°F. In addition to good corrosion resistance, this alloy also has good tensile strength.

Components manufactured according to ASTM A182 specifications include: B. 317L stainless steel flanges are intended for high temperature use. This specification takes into account the various requirements that these flanges must meet. Typically, ASTM A182, like most ASTM specifications, requires compliance with both mechanics and chemistry as well as test methods. After the hot forming process, the forged flange needs to be cooled to a certain temperature before heat treatment. The heat treatment performed on SS 317L blind flanges meets specific requirements, including: Type of heat treatment, cooling medium, austenitizing/solution temperature, and quenching.
