Alloy grade 316H or as referred to UNS S31609 is chemically similar to austenitic grade 316 stainless steel. Flanges produced with stainless steel, including grade 316H are to conform to the chemistry requirements of the ASTM A182 specification. In this case, the modification of the alloy i.e. Stainless Steel 316H Flanges is with an increase in the content of carbon, which has been associated with heat resisting properties. After hot working the alloy, the forgings according to ASTM A182 specification is to be cooled to a particular temperature setting before undergoing a heat treatment process. The heat treatment to be performed on the alloy of ASTM A182 F316H Flanges is to be done in accordance with certain requirements. For instance, the heat treatment type along with austenitizing/solution temperature, cooling media, as well as quenching are taken into consideration.

ASTM A182 F316H Blind Flange
ASME SA182 F316H Flanges
The main function of the A182 Grade F316H WNRF Flange is the transfer of stress from the flange itself to the pipe while reducing the concentration of stress from the base of the hub. The inside diameter of a weld neck grade 316H flange has been designed to match the inside diameter of the pipe and are recommended to be used for applications where high pressure is an integral factor. Usually, a SS 316H Blind Flange is used to seal or shut off the end of piping systems or pressure vessel openings. However, buyers across several industries use the blind 316H Stainless Steel Flanges for testing the flow of gas or fluid that passes through a pipe or vessel.
