Is a thermochemical surface treatment process designed to improve the surface hardness, wear resistance, and corrosion resistance of steel and other ferrous alloys. During this process, nitrogen and carbon are diffused into the surface layer of the material, forming a hardened compound layer, typically composed of iron nitrides and carbonitrides. Nitrocarburizing enhances the material's tribological properties, dimensional stability, and fatigue strength, significantly extending the lifespan of components subjected to high-stress and corrosive environments. This treatment is commonly used to improve the durability of gears, shafts, and other mechanical components.

Integral Batch Sealed Quench Furnace
Sealed Quench Furnace (SQF) is used for high-precision heat treatment primarily in auto components industry. This allows heat treatment for carbon steel to reach the desired hardness and strength. The furnace feature allows the materials to be processed in batches rather than continuous operation. HIGHTEMP is the leading manufacturer of Sealed Quench Furnace in India that provides a global clientele, with sales volume exceeding 500+.

Pit Type Furnace
Pit Furnace, also known as Pit-type Furnace, is an Industrial furnace used for heat treatment processes such as annealing, tempering, and hardening. The Pit Furnace is designed as a deep vertical cylindrical or rectangular chamber which can accommodate various sizes and shapes of materials. HIGHTEMP’s Pit Furnace is typically installed in a pit or deep chamber either below ground level or at ground level, which allows for easy loading and unloading of components.

Pit Type Gas Carburising Furnace
HIGHTEMPs Pit Type Gas Carburising Furnace is a specialized heat treatment solution designed for the gas carburising process, where carbon is diffused into the surface layer of steel components to enhance their hardness and wear resistance. Operating at temperatures typically ranging from 850°C to 950°C, our furnace ensures precise control over carburising depth and temperature uniformity. The vertical, pit-type design is ideal for treating long or large components such as shafts, gears, spindles, and axles, making it widely used in industries like automotive, aerospace, and heavy engineering. The furnace operates under a controlled atmosphere, ensuring consistent results and superior surface properties while maintaining core toughness.
