317L

 

      

Introduction

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.

The following datasheet provides an overview of stainless steel grade 317L.

Chemical Composition

The chemical composition of grade 317L stainless steel is outlined in the following table.

Element Content (%)
Iron, Fe Balance
Chromium, Cr 18-20
Nickel, Ni 11-15
Molybdenum, Mo 3-4
Manganese, Mn 2
Silicon, Si 1
Phosphorous, P 0.045
Carbon, C 0.03
Sulfur, S 0.03

Mechanical Properties

Manufacturing Process

Machining stainless steel grade 317L requires low speeds and constant feeds to reduce its tendency to work harden. This steel is tougher than grade 304 stainless steel with a long stringy chip; however, using chip breakers is recommended. Welding can be performed using most of the conventional fusion and resistance methods. Oxyacetylene welding should be avoided. AWS E/ER 317L filler metal is recommended.

Conventional hot working processes can be performed. The material should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). To optimize corrosion resistance, a post-work annealing is recommended.

Shearing, stamping, heading and drawing are possible with grade 317L stainless steel, and post-work annealing is recommended to eliminate internal stresses. Annealing is performed at 1010-1121°C (1850-2050°F), which should be followed by rapid cooling.

Grade 317L stainless steel does not respond to heat treatment.

Applications 

Grade 317L stainless steel is widely used in the following applications:

  • Condensers in fossil
  • Pulp and paper manufacturing
  • Nuclear fueled power generation stations
  • Chemical and petrochemical process equipment.
