Our Surface Hardening Range
We arrange case-hardening and through-hardening of rotating and sliding parts, with base stock from our Carbon Steel Supplier and Stainless Steel Supplier pages and matching service in our Heat Treatment Supplier page.
| Method | Case depth | Use |
|---|---|---|
| Carburizing | 0.5 to 1.5 mm | Gears, pins |
| Nitriding | 0.1 to 0.6 mm | Cylinders |
| Induction | 0.5 to 5 mm | Shafts |
| Flame | 1 to 3 mm | Large parts |
| Carbonitriding | 0.1 to 0.8 mm | Fasteners |
Choosing a Method
Carburizing and carbonitriding suit small loaded parts, nitriding gives low distortion and induction suits selective shaft hardening, with the property basis in our Hardness and Tensile Guide.
Core and Case Balance
A soft tough core resists shock while a hard case resists wear; verify each lot with our Quality Inspection Guide and documents per our Mill Test Certificate Guide.
Finishing and Protection
After hardening, coatings such as zinc or black oxide add corrosion resistance, with the options in our Surface Finishing Guide and the galvanized view in our Galvanized Steel Buyers Guide.
