317L Stainless Steel Overview
317L is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels.
The low carbon provides resistance to sensitization during welding and other thermal processes. This material also has a high resistance to pitting and crevice corrosion, making it suitable for use in the chemical and petrochemical industries, as well as in applications involving seawater and high chloride environments

The ASTM A182 F317L Flange is designed to ANSI B16.5 standard, the American National Standard Institute. It is available in various sizes and classes, making it suitable for a wide range of applications. This flange is commonly used in pipelines, valves, and other process equipment in the chemical, petrochemical, and oil and gas industries.
Types: Slip on, WN, SW, Threaded, Blind, Lapped joint, Long WN flange, ect.
Size: 1/2"-60"
Standard: ASME B16.5, ASME B16.47, DIN, EN, BS, JIS
Class: 150#,300#,400#,600#,900#,1500#,2500#
One of the key benefits of the ASTM A182 F317L Flange is its excellent weldability. This makes it easy to install and maintain, and ensures that it will provide a secure and leak-free connection between pipes or other equipment. The flange is also highly resistant to high temperature, making it suitable for use in applications that involve extreme heat.
