Stainless Steel S31703 Seamless Pipes have great formability, machinability, fabricability, weldability and wettability. Due to its fabricability pipes are easily modified into complex designs with traditional machines. However, with the machinability feature machining cost is decreased. This grade is only required standard machining feeds and speeds for a higher precise finish.
The SS 317L grade has higher weldability, it can be welded by all standard welding process such as TIG, MIG, resistance welding, submerged arc welding and more. Furthermore, this grade can be welded by with and without filler materials. These pipes are designed to lower to higher corrosion resistance in a wide range of processing streams. It is combined with resisting elements coupled with molybdenum content that assures higher resistance to corrosion. These pipes are highly alloyed in order to provide chloride stress corrosion cracking.
These pipes are highly resistive to stress corrosion cracking, crevice and pitting corrosion cracking. These pipes are basically made to perform in the environments having diluted sulfuric acids. Moreover, it offers higher resistance too many organic and inorganic compounds such as hot phosphoric acids. It has a good composition of alloying elements, provides exceptional resistance to general and uniform corrosion. It is one of the rare grade offer services in elevated temperatures.
