1050 Steel: Shafts and Surface Hardening

1050 belongs to the plain-carbon steel family, with more nominal carbon than 1020. Material reference.

Shafts and Surface Hardening

Use the shaft drawing to decide whether the requirement is bulk strength, a hardened journal or both. Comparing annealed 1050 with hardened alloy steel gives an unhelpful ranking; compare the proposed finished conditions and the largest section that must meet them.

Manufacturing and acceptance checks

State journal hardness separately from core requirements, identify the test location and retain finish-grinding allowance. Ask how straightness will be restored after hardening, and include inspection of transitions between hardened and unhardened surfaces in the acceptance plan.

Reference and scope

Baosteel: structural and spring steel grade families provides material or specification background. The checks above are purchasing guidance; final acceptance values must come from the agreed grade, product specification and condition.
