Vacuum carburizing method "Direct Carburizing (Multi Carbo)"

Vacuum carburizing method "Direct Carburizing (Multi Carbo)"

Fusion of gas carburizing and vacuum technology! No oxygen components in the atmosphere, no grain boundary oxidation, and excellent surface finish!

"Direct Carburizing (Multi Carbo)" is a new concept carburizing method that combines gas carburizing and vacuum technology. This technology utilizes vacuum (reduced pressure) to drastically reduce carrier gas and only uses a very small amount of chain-like unsaturated hydrocarbon gas as the carburizing gas. Since the atmosphere does not contain oxygen components, the alloy components on the surface do not oxidize, resulting in a good finish. It is environmentally friendly, high quality, and reduces operating costs by half. 【Features】 ■ No grain boundary oxidation (oxidation of surface alloy components) ■ Carburizing of pores is possible ■ High concentration carburizing is possible ■ Extremely shallow carburizing (30-50μm) is possible ■ Vacuum hardening is possible *For more details, please refer to the PDF document or feel free to contact us.

Technical Document "NITREG(R)-S Technology"

Technical Document "NITREG(R)-S Technology"

Gas nitriding of stainless steel with controllable nitriding potential!

"NITREG®-S technology" is a process that completely controls the formation of a nitrided layer on any stainless steel, with the potential for nitriding. [How it is controlled] The process is controlled in the following aspects*: - Diffusion proceeds under stable high quality nitriding conditions, similar to other metals, at appropriate temperature and time in a suitable atmosphere. The following aspects are controlled*: - Each process stage progresses in the appropriate order. [Features] ■ Achieves excellent wear resistance ■ Improves fatigue strength ■ Prevents wear ■ Green technology, zero pollution waste ■ Does not affect the magnetic properties of the steel *For more details, please download the PDF or contact us.

Gas Soft Nitriding Furnace "N2 Base Gas Soft Nitriding Furnace"

Gas Soft Nitriding Furnace "N2 Base Gas Soft Nitriding Furnace"

Gas nitriding furnace that helps conserve resources and energy!

The "N2 Base Gas Soft Nitriding Furnace" is a gas nitriding furnace that allows soft nitriding without using modified furnace gas in the atmosphere. By using a cooling chamber for cooling, the finish is bright and the mechanical properties are satisfactory. Additionally, since the goal is to achieve a bright finish, it can also be used for bright annealing and softening. 【Features】 ■ Resource-saving ■ Reduced running costs ■ Fast nitriding speed ■ No suiting ■ Bright finish *For more details, please refer to the catalog or feel free to contact us.

Technical Data "NITREG(R) - C Soft Nitriding"

Technical Data "NITREG(R) - C Soft Nitriding"

Gas soft nitriding/low-temperature soft nitriding (FNC) that can control nitrogen potential and carbon potential!

"NITREG®-C soft nitriding" is a gas soft nitriding process based on NITREG® nitriding potential control gas nitriding technology, which allows for the simultaneous diffusion of carbon and nitrogen into the surface of steel metals. The purpose of the NITREG®-C treatment is to create a hardened surface layer that enhances wear resistance and corrosion resistance, or improves fatigue strength in steel and cast iron components, without causing distortion or dimensional changes in the treated workpiece. 【Features】 ■ Promotes the formation of a compound layer (white layer) on low carbon non-alloy steel ■ Reduces production costs by using a more economical gas composition *For more details, please download the PDF or contact us.

Bell-type nitriding furnace

Bell-type nitriding furnace

It is possible to switch the atmosphere gas in the furnace depending on the properties of the material and the purpose of heat treatment.

Since the treatment is conducted at a lower temperature compared to conventional quenching, it is less likely to cause distortion in the steel material, allowing for the maintenance of dimensional accuracy. 【Specifications】 ● Temperature: 400–650℃ ● Atmosphere: Nitrogen / Ammonia gas / Nitrogen trifluoride ● Application: Nitriding ● Treated material: Stainless steel ● Treatment capacity: 1000Kg/ch ● Electrical capacity: 140kW 【Product Examples】Common products made in an atmosphere furnace ■ Engine parts ■ Display tube glass ■ Precision tubes for electrical testing equipment ■ Frying pans ■ CPU heat pipes 【Other Implementation Examples】 ■ Want to anneal aluminum without oxidation → 'Roller hearth softening furnace' ■ Want to carburize materials → 'Batch-type atmosphere gas carburizing furnace' If you have any new challenges or inquiries regarding energy conservation, automation, environmental considerations, or safety, please feel free to reach out. *For more details, please refer to the PDF materials or feel free to contact us.
