Publisher's Synopsis
Excerpt from Workshop Hints for Munition Workers
Case-hardening gives a thin film of hardened steel to wrought-iron or mild steel, and is adopted both to enable faces to resist wear and for good appearance. Certain parts or fittings are case-hardened, often with a Special mottled finish, only for pleasing appearance. Or sometimes a high polish is put on after case-hardening, only sufficient material being polished off to eliminate the surface markings which the case-hardening makes.
