AUSTEMPERING FURNACES

The Austempering process is a unique heat treatment method that stands out among other hardening techniques. Its key advantage lies in achieving high hardness while retaining exceptional toughness, springiness, and elongation properties often compromised in conventional hardening. This process produces a durable bainite microstructure, making it ideal for applications requiring both strength and flexibility.

Microstructural changes provide strength and durability for steel spring applications such as Spring, Wave Spring and WASHER and Clamp or other types.

PC Products International Co Ltd maintains a strict quality assurance system with automated 5-second parameter recording for full traceability. Core hardness testing, microstructure analysis, and comprehensive workpiece documentation (covering both side and axial sections) ensure zero risk of part failure. Each part number follows a dedicated process control program with 15-minute inspections, while statistical process control (SPC) and continuous review processes guarantee consistent quality across all production batches.

If you need spring components with exceptional elasticity, fatigue resistance, and the perfect balance of hardness and toughness - all without cracking - our Austempering hardening process delivers exactly that. We specialize in this advanced heat treatment method to provide you with superior performance parts that withstand repeated stress while maintaining structural integrity.

The Austempering process produces a lightweight Bainite microstructure by quenching in salt above the steel's MS (martensite start) temperature. This method significantly reduces part distortion, minimizes spring back effects, and lowers cracking risks commonly associated with partial oil quenching processes.

Moreover, the process is engineered to produce bainitic microstructure, with all hardness parameters and process variables being monitored through both manual and electronic verification systems (recorded every 5 seconds). Each process setup is configured by certified technicians. This method prioritizes optimal hardness, controlled microstructure development, and distortion minimization through proper part loading configurations on furnace conveyors (some distortion may still occur due to part geometry). The furnace undergoes periodic validation to ensure and demonstrate consistent temperature uniformity throughout the chamber.
