Alloy 317/317L is good for needle and gauge valves manufacturing?
Alloy 317/317L is austenitic stainless steel. It is composed of a higher amount of chromium, nickel and molybdenum element that offers exceptional resistance to corrosion and abrasion. This grade can be exposed to different acidic environments and offer great service in the chemical effects. The lower version “317L” is developed for the resistance to intergranular attacks in the most severe environments. This alloy has the ability to perform in elevated temperatures while offering great tensile strength. Even though, it is weldable with most standard techniques. It is machinable with machines which are associated with standard 317 stainless steels. Thus, this reduces its machining costs for industrial applications.
These needles and gauges valves are formed by hot working methods. It is processed from the heat treatment process in temperatures between 1149 deg C to 1260 deg C. It is subjected to post work annealing process that retains its higher corrosion resistance properties.
We have modern in-house testing equipment and facilities to ensure the supply of top quality finished products. Different types of tests are performed in our testing facility by professionals considering the application requirements of the customers. We are committed to providing high-quality SS 317 / 317L Needle & Gauge Valves at most reasonable rates to our overseas customers. In the testing facility Valve seat leakage test, backseat test, closure test, shell leakage test, pneumatic test, hydrostatic test, Cryogenic testing, low-temperature testing, and high temperature tests are performed by us. Other tests include burst tests, fire safety tests, functional tests (relief test, transfer valve test), drill stem test, traveling valve test (TV) test, intergranular corrosion test, and more.
Steel 317 / 317L Needle & Gauge Valves are delivered by us in the industrial standard packing of wooden cases, cartons, pallets, and boxes. also, we provide customization option to customers for packaging.
