Flame Hardening
PLEASE NOTE: Thermex no longer offers Flame Hardening as a service. This page remains live for information purposes only.
Flame hardening is a surface hardening process used on medium carbon mild or alloy steels (such as 1045, 4140, 4340), or cast irons, to produce a hard wear resistant surface (case) on the part.
The surfaces to be hardened are heated with an array of torch heads that produce a high temperature intense flame for rapid heating of the part surface. Parts are then quenched into a water-based polymer quench. Typical surface hardness range is 55-60 HRC in medium carbon steels.
- Suitable for medium carbon alloy steels, cast irons
- Produces a hard wear resistant surface
- Surface hardness range is 55-60 HRC
- Water-based polymer quench
Flame hardening is used on parts such as crane wheels, cable sheaves, and rollers. Please contact us to discuss your specific requirements.
