Heat treatment processing service "Austemper"

Heat treatment processing service "Austemper"

The bending is surprisingly small! The austempering heat treatment achieves minimal deformation and dimensional changes while also providing toughness!

Austenitizing is a type of quenching and tempering that results in less deformation and distortion compared to conventional quenching and tempering processes. Not only does it minimize deformation, but it also enhances toughness and impact resistance, resulting in significantly different strength levels even at the same hardness compared to traditional quenching and tempering. 【Features】 ■ Minimal deformation and dimensional changes ■ Impact values are 2 to 3 times higher compared to materials of the same hardness *For more details, please refer to the external link or feel free to contact us.

Heat treatment processing service "Carburizing Quenching"

Heat treatment processing service "Carburizing Quenching"

It achieves low deformation and dimensions, high strength, and high wear resistance!

Our company receives many orders for "carburizing and quenching" of small precision parts. Compared to gas carburizing, it has better carburizing efficiency and can be performed at lower temperatures, resulting in less thermal deformation. Additionally, during carburizing heating, the buoyancy of the salt reduces deformation caused by the weight of the parts. Please feel free to contact us if you have any requests. 【Features】 - Heating in salt (liquid) minimizes the influence of radiant heat from the furnace heaters, allowing for uniform heating. - Carburizing in higher temperature salt, which allows for sufficient quenching, controls thermal shock deformation and stress associated with phase transformation to the minimum necessary. - Uniform formation of extremely thin carburized hardened layers of less than 0.1 mm on small parts, etc. *For more details, please refer to the external link or feel free to contact us.
