Specialty
Bar Products Company: Heat Treatment Services for Custom Machined
Parts
Specialty Bar Products Company (SBP) provides superior custom machining services for the production of high-performance steel parts and components. Heat treatment services at SBP are used to alter the toughness and hardness of metal. Many of the custom parts that Specialty Bar Products manufactures require not only strength but also ductility to avoid failure, breakage, snapping, shattering, or deformation during use. Specialty Bar Products uses the following heat treatment equipment to offer customers effective heat treating services for custom components:
Salt Bath Production Line – maximum temperature: 1650º F
4 Tocco Induction Hardening Machines
2 Lindberg Pit Furnaces, maximum load weight: 1200 lbs
Lindberg Internal Quench Furnace, maximum load weight: 600 lbs
1 Ipsen Internal Quench Furnace, maximum load weight: 500 lbs
Above Furnaces: Endothermic Atmosphere
3 Lindberg Draw Furnaces
1 Lindberg Spray and Immersion Wash Unit

Induction Hardening for Custom Parts
Induction hardening relies on an induction heating furnace to create an electrical voltage within the steel bar component. The steel is heated to right below its melting point and then is rapidly quenched. This greatly increases the hardness and brittleness of the steel part.
Through Hardening vs. Case Hardening for
Custom Components
SBP uses through hardening to increase strength throughout the steel part. This heat treatment process differs from case hardening, also known as surface hardening, which heats the surface metal, changing the grain structure of the outer part of a steel component but allowing the core to retain ductility. Unlike through hardened parts, case hardened components gain strength without losing significant toughness.
Stress Relieving Services for Precision Parts
An important process for ensuring that a part does not deform or fail in the long term, stress relieving involves heating a steel part or component until the steel reaches a uniform temperature. The part is then allowed to cool in still air. This process removes internal stresses caused by high-speed machining and ensures a longer service life.
Quenching and Tempering Steel Parts
Rapid cooling of a part is often necessary after hardening. Salt bath, oil quench, and water quench are all available at Specialty Bar Products Company. Tempering can be performed after quenching and is necessary to restore ductility to a component after hardening. By being tempered, the steel part is allowed to retain higher levels of strength but regain the softness that allows it to be clamped or have external stresses applied to it without snapping, shattering, or cracking.
