Roll-bonded nitrogenated 201 stainless steel.
J Mater Sci 1995 Jan; 30(16):4103-4106
An alternative to high-pressure melting was used to produce sheets of high-nitrogen stainless steel. Hot isostatic pressure diffusion of nitrogen into thin sheets of 201 stainless steel resulted in enhanced nitrogen concentrations unobtainable in commercial grade stainless steels. Several different nitrogen enhancement techniques were attempted. Hot roll-bonding was then used to produce thick laminates. The resulting tensile strengths were dependent upon the nitrogen concentration of the laminates and were similar to the tensile strength obtained for high-pressure melted nitrogen stainless steels.
