Steel material of high fatigue strength and a process for manufacturing the same |
摘要 |
A hot worked steel material, such as a bar, or tube, has a surface layer improving its fatigue strength despite the non-metallic inclusions which it may contain, or the cracks which it may have. The surface layer is formed by heating a nickel layer on the steel surface to cause the diffusion of nickel therethrough. |
