The application of flame hardening is unlimited.  Production problems and wear problems on gears, sprockets, cams, crane wheels, mill rolls and similar components can be solved with surface flame hardening.  For example, only flame hardening the teeth of gears dramatically extends the life and wear of the part without a substantial cost increase.  This also allows the part to be machined after heat treatment.   Flame hardening is utilized typically for the following components and parts, from 1 ounce to over 6 to 8 tons: Gears (up to 10 feet in diameter) All Industrial Sprockets (1 to 1000lbs+) Shafts (1 inch to 16 inches in diameter / 1 foot to 10 feet long) Oil Tools and Mining Equipment Wheels, Tubes,  Bushings, Extruder Screws, Rollers and more are all items that can benefit from flame surface hardening California Surface Hardening, Inc. can also accommodate specialty geometries and work on-site at your facility (or jobsite) for jobs too big,  or for added convenience.   Contact us today to discuss how California Surface Hardening, Inc. can assist your business.
