An ISO 9001, ISO 14001, OHSAS 18001 Certified Company & GOVT. OF INDIA RECOGNIZED EXPORT HOUSE, PED Certified, Ashtapad Overseas is India’s most trusted manufacturer of Stainless Steel 317L Flanges, Stainless Steel 317L Pipe Flange and High Pressure Stainless Steel 317L Flange. All our Stainless Steel 317L Flanges are manufactured with tested raw materials and are supplied with NABL approved lab test reports. On demand, we can also provide, Hydro Testing Reports, Non Destructive Test Reports, or Destructive Test Reports. Stainless Steel 317L Flanges are manufactured in accordance with ASTM, DIN and ISO specifications & 3.1 certified material.

Our Stainless Steel 317L flanges, collars and rings are forged or seamless rolled. The manufacturing process includes an adequate heat treatment and the examination of technological and mechanical properties. The final finishing happens on appropriate CNC machines, as well as on conventional lathe, depending on the size. The screw holes are generally drilled to ensure a flat surface for srews. A Stainless Steel 317L Flange, a collar or a seamless ring is produced to order by the corresponding flange standards DIN, EN, ANSI, GOST, JIS and other international norms and standards or according to customer specifications.

Ashtapad Overseas is a specialized manufacturer in the production of Stainless Steel 317L flanges with customized dimensions as per our customer drawing. Especially in the area of lapped (loose) flanges (DIN 2641/2642 / EN1092-1 Typ 02), flanges for soldering or welding (plate / plain flange) (DIN 2573/2576 / EN1092-1 Typ 01) and blind flanges (DIN 2527 / EN1092-1 Typ 05) price reductions could be realized by using reduced – but the demands sufficient – blade thicknesses instead of the standard.

We manufacture Stainless Steel 317L flanges dimensions according to the complete standards range from DN10 up to DN2400, respectively 1/8” up to 60”. All other dimensions beyond this range on request.

Key Properties of ASTM A182 F 317L Stainless Steel Flanges

  • High corrosion resistance in tough environments
  • Lower intergranular precipitation
  • High resistance to pitting and crevice corrosion

Common Applications ASTM A182 F 317L Stainless Steel Flanges

  • Pulp and paper manufacturing plants
  • Chemical processing equipment
  • Petrochemical processing equipment
  • Textile machinery and equipment
  • Vessels and tanks

317L is an molybdenum-bearing austenitic stainless steel, with greatly increased resistance to chemical attack as composed to the conventional chromium-nickel austenitic steel tubes as 304L & 316L. the addition of molybdenum gives alloy 317L tubing improved resistance to chloride and other halides. Due to its low carbon content the 317L tubing can be welded without risk of sanitization due to inter granular corrosion that can result from chromium carbide precipitation in the grain boundaries. 317L is non magnetic in the annealed condition, but may become slightly magnetic as result of welding.

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 steels increases with the alloy’s molybdenum and nitrogen content.

7 vol.%H2SO4, 3 vol%HCI, 1 wt% CuCl2, 1 wt%FeCl3
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 steels are similar to those of more conventional austenitic stainless steels and can, therefore, be fabricated in a manner similar to Alloys 304 and 316.
