Being the well-known industry we Astec Tubes is quite busy in manufacturing, supplying and exporting the commendable quality of SS 317/317L pipe fittings in an extensive collection. As we provide the same to our clients in various specifications so it can be easily acquired at various standards, wall thicknesses, types, and sizes. It is too manufactured and offered at cut-made specifications & standards as per the client’s demands. Our SS 317 pipe fittings and SS 317L pipe fittings are designed by using premium quality of alloy and as per the manufacturing norms and industry standards like ASTM, ANSI, ASTM, API, etc. Type stainless steel 317 is the austenitic nickel and chromium-based stainless steel with phenomenal resistance to corrosion. The greater content of the molybdenum alloying element is improving the material’s pitting resistance. It is one of most resistant to corrosion material of 300 series material and it is possessing very good creep strength and high tensile properties at the greater temperature.

Type stainless steel 317L is the low carbon austenitic nickel and chromium-based stainless steel material that can be used in the applications wherein it isn’t possible to anneal after the welding and also wherein greater corrosion resistance is needed. It is giving very good resistance to oxidation property in the continuous and intermittent services at 1700 deg F and 1600 deg F respectively.UNS S31700 pipe fittings and UNS S31703 pipe fittings are having very good features in it due to which the greater usability of it has been seen in various industries. It is having well-improved general & localized corrosion, good weldability, good formability, perfect dimensional accuracy, sturdy construction, holds high heat and pressure, high toughness, etc.
