ASTM A240 S31753 / 317LN Stainless Steel Plate 0.5 - 30.0mm SS Plate AISI317LN Stainless Steel Plate

Stainless steel 317LN is a nitrogen alloyed austenitic stainless steel having high nitrogen content than other austenitic stainless steels. It has higher yield and tensile strength than 317L. This low carbon grade steel provides resistance to sensitization during welding and thermal processes. Low carbon content in its composition makes the alloy resistant to inter granular corrosion. It also offers excellent corrosion resistance to organic, sulfuric and phosphoric acids.

Chemical Composition

The chemical composition of Grade 317LN stainless steel is outlined in the following table.

Element	Content (%)
Iron, Fe	63.43
Chromium, Cr	18.2
Nickel, Ni	14
Molybdenum, Mo	4.2
Nitrogen, N	0.15
Carbon, C	0.02

Mechanical properties

The mechanical properties of Grade 317LN stainless steel are displayed in the following table.

Properties	Metric	Imperial
Tensile strength	≥590 MPa	≥85600 psi
Yield strength	≥285 MPa	≥41300 ksi
Modulus of elasticity	200 GPa	29000 ksi
Shear modulus	77 GPa	11200 ksi
Poissons ratio	0.299	0.299
Elongation at break	≥40%	≥40%

Manufacturing process

The properties of 317LN is similar to other conventional austenitic stainless steels, and can therefore, be fabricated in a manner similar to alloys 316L and 317L. Heat treatment of 317LN can be carried out at temperatures ranging from 1080 to1175°C (1975 to 2150°F) followed by rapid water quenching. This grade is not hardenable.

Applications

The following are some of the major applications of Grade 317LN stainless steel:

Chemical and petrochemical industries
Pollution control equipments
Chemical tankers
