Flame hardening is a surface-hardening method that involves heating a metal with a high-temperature flame, followed by quenching. It is used on medium carbon, mild or alloy steels or cast iron to produce a hard, wear-resistant surface. Flame hardening uses direct impingement of an oxy-gas flame onto a defined surface area. The result of the hardening process is controlled by four factors: 1. Design of the flame head 2. Duration of heating 3. Target temperature to be reached 4. Composition of the metal being treated. Typical flame-hardening applications include: Blades, Gears, Rolls, Cams, Automotive components. We have over 100 years of combined flame hardening experience and also possess the ability to fabricate torch heads to fit any job.
Induction hardening is a heat treatment process carried out to enhance the mechanical properties in a localized area of a ferrous component. The resultant hardened area improves the wear and fatigue resistance along with strength.
Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole. It is favored for components that are subjected to heavy loading, torsional loading and impact forces.
Black oxide is a conversion coating that is used for appearance and to add mild corrosion resistance and minimize light reflection. Black oxides are used where component accuracy and tolerance are paramount, compared to painting methods. It is used in fasteners, weldments, tooling and casting where oil retention and appearance are essential. It also provides a deep black color when used with proper post dips.
Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact temperature determines the amount of hardness removed, and depends on both the specific composition of the alloy and on the desired properties in the finished product.
In metalworking, the elimination or reduction of unnecessary curvatures in metal items by the application of external forces. Straightening is used in the production of sheets, tubes, rails, beams, and other milled items. In press straightening, the item to be straightened is placed on two supports and force applied to the uneven surface causes elastoplastic deflection.
Shot & Air Blasting
Shotblasting is a method used to clean, strengthen (peen) or polish metal. Shot blasting is used in almost every industry that uses metal, including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others. There are two technologies used: wheelblasting or airblasting.
Wheelblasting directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. The capacity of each wheel goes from approximately 60 kg per minute up to 1200kg/min. With these large amounts of accelerated abrasive, wheelblast machines are used where big parts or large areas of parts have to be derusted, descaled, deburred, desanded or cleaned in some form.
Airblast machines can take the form of a blastroom or a blast cabinet, the blast media is pneumatically accelerated by compressed air and projected by nozzles onto the component. The blasting task determines the choice of the abrasive media.
Westside Flame Hardening, Inc. Statement of Liability
All work is accepted subject to the following conditions:
“It is generally recognized that even after employing all the science known to us and capable men with years of training, there still remains hazards in flame hardening. Therefore, our liability to our customers shall not exceed twice the amount of charges for the work done on any material, (first to reimburse for the charges and second to compensate in the amount of the charges), except by written agreement. There are no warranties that extend beyond the face hereof or the provisions contained herein. Any further warranties or liability will be assumed by us only when reduced to writing and signed by both you and us. In such event a higher charge will be made for our services. No materials by the customer. No claim will be allowed for shrinkage, expansion, deformity, or rupture of material in treating or straightening, except by written agreement, signed by both you and us, nor in any case for rupture caused by subsequent grinding. Whenever we are given material with detailed instructions as to treatment, our responsibility shall end with carrying out of these instructions. The customer agrees that failure by him to indicate plainly and correctly the kind of material (i.e., make, brand and grade of steel) to be treated shall cause an extra charge to be made to cover any additional expenses incurred by us as a result thereof. It shall be the duty of the customer to inspect the merchandise immediately upon its return and in any event claims must be reported prior to the time any further processing, assembling or any other work has been done on said material. No agent or representative is authorized to alter these terms and conditions except by writing signed by us. It is further expressly agreed that the remedies outlined herein shall be the exclusive remedies of the customer. It is further agreed that there shall be no liability for consequential damages.”
