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.
