We provide contract processing for bright heat treatment at our Nasu factory in Tochigi Prefecture. Located in the northern Kanto region, it serves as a gateway to Tohoku, which helps reduce transportation costs for the metal materials to be processed. We have installed a 3000㎥ hydrogen tank, enabling us to perform hydrogen treatment that beautifully finishes heat treatment work at a low cost. ● In bright heat treatment of stainless steel... We use a hydrogen atmosphere for rapid and precise heating and cooling. We achieve uniform finishing from precision machined parts to long items like pipes. ● In oxidation-free furnace brazing... We accommodate various brazing processes for materials that are difficult to weld, dissimilar metals, complex shapes, and simultaneous joining of multiple points. We also offer consultations on selecting brazing materials and various conditions such as temperature and atmosphere. *For customers considering the introduction of heat treatment equipment due to increased heat treatment products, shortened delivery times, or acquiring technology in-house, we can propose heat treatment equipment that meets your requirements. We conduct sample tests and provide condition proposals during the introduction process.

<<Annealing>> It can reduce the hardness of metal materials (make them softer). This treatment is often performed to facilitate subsequent processing. ◆ Examples of treated items ⇒ Flexible pipes, pipes for automotive parts, watch components, bellows, various pressed parts, etc. <<Solution treatment>> It can remove residual stress and work hardening, improving workability and corrosion resistance. This treatment is often performed after processing stainless steel products. ◆ Examples of treated items ⇒ Stainless steel pipes, tableware, stainless steel bands for watches, various pressed parts, etc. <<Quenching>> It can increase the hardness of metal materials (make them harder). This treatment is often performed to increase hardness and make items less prone to breaking and more durable. ◆ Examples of treated items ⇒ Knives, scissors, disc brakes, tools, various cutting tools, micro shafts for small motors, etc. <<Brazing>> It can join base metals with high precision using filler metal. This treatment is often used for materials that are difficult to weld, dissimilar materials, small parts, and complex shapes. ◆ Examples of treated items ⇒ Heat exchangers, automotive parts, hydraulic equipment, gas equipment, construction parts, agricultural machinery parts, stainless steel filters, etc.
