Gas Carburizing Treatment

Carburizing-quenching treatment is a method of putting the products into a furnace with an air atmosphere that has increased carbon concentration, causing the carbon to penetrate the product surface at a temperature of around 900℃, then perform the quenching process to change the metal structure, hardens the product.

Carburized quenched products surface has increased hardness and excellent abrasion resistance. Furthermore, the structure of product core is still flexible, and has excellent overall flexibility to ensure impact resistance. Gas carburizing treatment is commonly used as a heat treatment method to harden metal products, widely applied to many kinds of equipment parts such as auto parts, motorcycle parts and construction equipment parts.

At PPV, we started carburizing treatment from 2005, so far we have invested in 11 batch type gas carburizing furnaces. Beside carburizing treatment, we can meet other quality needs such as carbonitriding treatment, quenching tempering treatment (high temper, low temper), anti-carburizing treatment, press-tempering etc…
