Abstract
In a surface layer of an ultra-low carbon stainless steel comprising a seal function layer in the surface layer, an ion such as a nitrogen ion is implanted to form the seal function layer. Since the ultra-low carbon stainless steel comprising the seal function layer is excellent in elasticity, sealing properties, peelability and abrasion resistance, it can make a seal material which has been used unnecessary, and can realize all stainless-made products such as seal and joint system parts.
Claims7
An ultra-low carbon stainless steel which comprises a seal function layer in a surface layer,
- wherein the seal function layer is formed by an ion implantation method, and
- the ultra-low carbon stainless steel contains carbon in an amount limited to 0.006% to 0.008% by weight.
A member with a seal function, the member comprising an ultra-low carbon stainless steel containing carbon in an amount limited to 0.006% to 0.008% by weight, wherein the seal function layer is formed by ion implantation on the surface of the ultra-low carbon stainless steel.
