No soot generation (suiting)!
◯ No grain boundary oxidation, and the finish surface is good. ◯ High concentration carburizing is possible. ◯ Carburizing into pores is possible. ◯ No CO2 emissions from furnace exhaust. ◯ Carburizing time is about half compared to gas carburizing. ◯ The amount of carburizing gas used is less than 1% compared to gas carburizing.
Prevention of defects such as cracks: The higher the hardness of the material, the more important this process becomes as the sensitivity to cracking increases.
Overlay welding is performed not to join metals, but to impart wear resistance, corrosion resistance, and heat resistance to the surface of the metal. The reasons for performing overlay welding include the high cost of manufacturing entire components from such specialized metals, technical difficulties, and the need to repair worn components due to operational loads. The importance of this process increases as the hardness of the material rises, leading to greater sensitivity to cracking. At Martec, we are well-versed in the characteristics of high-hardness materials, which is why we carry out post-processing that pursues quality.
Is it true that after electroless nickel plating and then heat treatment, it can be hardened to about 900 Hv with a Vickers hardness test?
Q: Is it true that after electroless nickel, heat treatment can achieve hardness of about 900 Hv with Vickers? A: It is possible. Electroless nickel plating can achieve hardness exceeding 900 HV by heat treating at 400 degrees after plating, which changes the crystal structure.

Increased shot count by over 10 times due to wear resistance! Improved shot count with gas soft nitriding treatment for resin molds "Slide Core."
The gas soft nitriding treatment for resin molds "slide cores" is a heat treatment for mold components that experience significant wear due to abrasion. There are records showing that the number of shots has increased more than tenfold compared to mold components that have not undergone gas soft nitriding treatment. 【Features of Gas Soft Nitriding Treatment】 ■ Strong improvement in wear resistance and corrosion resistance ■ Effective for products with strict dimensional accuracy by suppressing distortion ■ Adopts retort outer cooling method to reduce the load on products ■ Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish ■ Effective up to Φ600mm×1000mm

There are four types of heat treatment: quenching, tempering, annealing, and normalizing.
This is the basic form of heat treatment, with quenching being its representative. Annealing is performed to soften steel, while tempering is done to make it tougher. In addition to these, there are heat treatments such as carburizing quenching and high-frequency quenching that harden the surface, but these are merely applications of the basic heat treatments. With the development of the machinery industry, needs have diversified, and in response, heat treatment has become complex and varied, but the fundamental forms are undoubtedly the four: quenching, tempering, annealing, and normalizing. ★ For inquiries by phone, please contact us here: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros was seen."
