Description

ASTM A182 F310 Stainless Steel Weld Neck Forged Flange RTJ ASME B16.5

Product Overview

ASTM A182 F310 Stainless Steel Weld Neck Forged Flanges are manufactured from high-temperature resistant 310 stainless steel alloy and designed according to ASME B16.5 standards. These forged flanges provide excellent oxidation resistance, corrosion resistance, and mechanical strength at elevated temperatures, making them ideal for petrochemical plants, power generation facilities, refineries, heat exchangers, and industrial piping systems.

The Ring Type Joint (RTJ) facing design ensures superior sealing performance under high-pressure and high-temperature operating conditions. F310 stainless steel contains high chromium and nickel content, offering outstanding resistance to oxidation and thermal cycling.
