Step 1
Common routes
- Carburized steel: case/core, distortion and finishing
- Induction hardening: pattern, depth and root coverage
- Nitriding: case, core and finishing sequence
- Through hardening: hardness, toughness and section size
- Bronze: alloy, condition, defects and mating worm
Step 2
Drawing controls
- Material and substitutes
- Treatment and hardness scale
- Case-depth definition and location
- Finish after treatment
- Distortion and straightening policy
- Coupons and reports
Step 3
Engineering principle
- Hardness alone does not solve bending, pitting, wear or impact
- Geometry, toughness, finish, lubrication and load distribution matter
