317 317L Stainless Steel Seamless Pipe stainless steel seamless tubing Supplier
HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel Tube.Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.
Description:
Stainless steel 317L is a molybdenum grade containing low carbon, along with additions of chromium, nickel, and molybdenum. This offers better corrosion resistance and increased resistance to chemical attacks from acetic, tartaric, formic, citric, and sulfuric acids. 317L tubes/pipes provide higher creep, and resistance to sensitization when welded, due to low carbon content. Added benefits include stress to rupture resistance, and tensile strength at elevated temperatures. Grade 317l steel pipes are non-magnetic in the annealed condition. However, post-welding slight magnetism may be observed.
317L stainless steel pipe 317L stainless steel tubes supplied by Shanghai HaoSteel contain the following properties:
Corrosion Resistance:Exhibits exceptional corrosion resistance in diverse environments, especially in acidic chloride environments and a wide range of chemicals
Excellent corrosion resistance in applications where minimum contamination is required 317L stainless steel tubes/pipes with low carbon content offer good resistance to intergranular corrosion
The tendency of steel to pit when coming in contact with chlorides, bromides, phosphorus acids, and iodides is suppressed
Heat Resistance:
Excellent resistance to oxidation due to chromium-nickel-molybdenum content.Exhibits a low rate of scaling at temperatures up to 1600-1650°F (871-899°C), in ordinary atmospheres.
Welding Characteristics:
Except oxyacetylene welding, successfully welded by all common fusion and resistance methods.Filler metal with nickel-base and sufficient chromium and molybdenum content should be used to weld Type 317L steel. This helps in enhancing the corrosion resistance of welded product. AWS E317L/ER317L or austenitic, low carbon filler metals having higher molybdenum content than grade 317L can also be used.
Machinability:
Working at Low speeds with constant feeds helps minimize the tendency of grade 317L pipes to harden.Grade 317L stainless steel pipes are tougher than 304 stainless and subject to long and stringy chip when machined. Hence, the use of chip breakers is recommended.

Alloy 317L (UNS S31703) is a molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Alloy 304. In addition, Alloy 317L offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon or "L" grade which provides resistance to sensitization during welding and other thermal processes.
Stainless steel grade 317L is a low carbon version of grade 317 stainless steel. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.
