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.
The chemical composition of Grade 317LN stainless steel is outlined
in the following table.
The mechanical properties of Grade 317LN stainless steel are
displayed in the following table.
|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|
|Elongation at break||≥40%||≥40%|
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
The following are some of the major applications of Grade 317LN
- Chemical and petrochemical industries
- Pollution control equipments
- Chemical tankers
