Product Description

Product Description

Introduction

Stainless steel 317LN Sheet 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 Sheet. 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.

Technology

The properties of 317LN Sheet 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

317LN stainless steel Sheet is harmless to the human body, lead-free and non-toxic, and has good corrosion resistance and oxidation resistance, which makes it an ideal material for medical device manufacturing. Specifically, 317LN stainless steel is often used to manufacture surgical instruments, medical equipment and implantable medical devices, because it can withstand the erosion of chemical media for a long time and maintain good hygiene performance, and will not cause pollution or harm to the medical process.
