What Is 317L– UNS S31703, 1.4438 Stainless Steel EFW pipes ?
ASTM A358 TP317L Stainless Steel EFW pipes, UNS S31703 EFW pipes, WNR 1.4438 EFW Tubes Supplier
317L is molybdenum bearing austenitic stainless steel similar to 316, but with higher molybdenum alloy content. It is also known as UNS S31700, and is primarily comprised of 18% to 20% chromium and 11% to 15% nickel.317L offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional Stainless Steel. It is a low carbon grade which provides resistance to sensitization during welding and other thermal processes.
EFW namely the abbreviation of the first letter for Electric welding Electric fusion welding.Submerged arc welding (SAW) pipe is a kind of EFW pipe,containing the LSAW steel pipe and SSAW steel pipe. EFW is a kind of technology process - heating the metal to combine,which is caused by the interaction between the one or a few consumable electrode and workpiece,and the arc shall fully melt the metal and the filler material, do not need to pressure,and filler metal part all comes from the electrode.

The low carbon (less than 0.03%) of these alloys effectively prevents sensitization to intergranular corrosion during thermal processes such as welding or forging. The higher chromium contents of 317LMN and Alloy 317L Stainless Steel also provide superior resistance to intergranular attack. It should be noted that prolonged exposure in the range 800 to 1400°F (427-816°C) can be detrimental to intergranular corrosion resistance and may also cause embrittlement due to precipitation of sigma phase. The higher nitrogen content of the 317LMN alloy retards the precipitation of sigma phase as well as carbides.
Pitting Resistance Equivalents |
|
Alloy |
PRE |
Alloy 317L |

High molybdenum and nitrogen contents can significantly improve pitting resistance as illustrated in the preceding table of Pitting Resistance Equivalents (PRE). The PRE is based on the results of corrosion tests in which it was found that nitrogen was 30 times more effective than chromium and approximately 9 times more effective than molybdenum in enhancing chloride pitting resistance.
The temperature of the onset of crevice corrosion as determined in a modified AST G-48B test is a useful means of ranking the relative resistance of stainless and nickel-base alloys. The Critical Crevice Corrosion Temperatures table that follows demonstrates that crevice corrosion resistance for austenitic Stainless Steel increases with the alloy€™s molybdenum and nitrogen content.

- » Oxidation Resistance
The chromium-nickel-molybdenum steels all have excellent resistance to oxidation and a low rate of scaling in ordinary atmospheres at temperatures up to 1600-1650°F (871-899°C).
- » Fabrication
The physical and mechanical properties of 317LMN and Alloy 317L Stainless Steel are similar to those of more conventional austenitic Stainless Steel and can, therefore, be fabricated in a manner similar to Alloys 304 and 316.
