Introduction to the "Heat Treatment Technology" Materials

Introduction to the "Heat Treatment Technology" Materials

A document featuring heat treatment technology that breathes life into metals!

This document provides an overview of heat treatment technology offered by the Japan Metal Heat Treatment Association. Metal heat treatment is a processing technology that improves the properties of metal materials through a combination of heating and cooling without changing the shape of the product. Among the metal materials subjected to heat treatment, iron has been the most widely used, and non-ferrous alloys (such as aluminum alloys and titanium alloys) are also subjected to heat treatment. [Contents] ■ Types of metal heat treatment processes - General heat treatment (heat treating the entire product) - Surface heat treatment (heat treating only the surface) ■ Heat-treated products commonly used in automobiles ■ Everyday heat-treated products *For more details, please download the PDF or feel free to contact us.

[Proposal / Solution Case] Product Distortion

[Proposal / Solution Case] Product Distortion

Case Study 2: "Improving mechanical properties leads to strain."

We would like to introduce a case study of metal heat treatment that our company proposed. The inquiry was about preventing significant "distortion" in parts with uneven wall thickness, which was causing residual scale during subsequent machining processes. The greater the temperature difference within the product during heating and cooling, the more significant the "distortion" that occurs after heat treatment. Our company ensures that the entire product is uniformly heated and cooled by aligning and setting the products for heat treatment, whether in continuous furnace processing or batch furnace processing. [Case Study] ■ Issue Significant "distortion" in parts, leading to residual scale during subsequent machining processes. ■ Solution Conducting heat treatment by aligning and setting the products to ensure uniform heating and cooling of the entire product. *For more details, please feel free to contact us.

Salt Bath / Oustenber

Salt Bath / Oustenber

Same-day response is possible! Since we can perform both heat treatment and surface treatment, we can handle everything consistently with a single request.

Our company offers processing using salt baths and austempering. The advantage of salt baths is their flexibility. Unlike large equipment that requires waiting for a batch to be completed, the ease of adjustment allows for shorter delivery times. Austempering is a type of quenching and tempering that results in less deformation and distortion compared to conventional quenching and tempering. It also has greater toughness and higher impact resistance, so even at the same hardness, the strength is completely different from that of conventional quenching and tempering. 【Features】 ■ Same-day response available ■ Salt bath: Achieves short delivery times with ease of adjustment ■ Salt bath: Can suppress bending and deformation ■ Austempering: Processing with less deformation and distortion compared to conventional quenching and tempering ■ Austempering: Greater toughness and higher impact resistance *For more details, please refer to the PDF document or feel free to contact us.

Local control of pipe material thickness is possible! Furthermore, it is possible to achieve both lightweight and high strength through induction heating treatment.

Butted processing allows for flexible adjustment of the thickness of pipe materials through inner and outer diameter drawing. It enables inner diameter slimming without cutting! This contributes to weight reduction and material cost savings. Additionally, even in thin sections, performing IH heat treatment provides high strength and high toughness, achieving high bending fatigue strength. Example) "Before processing" Weight: 704g Total length: 300mm ↓ "After butted processing" Weight: 576g Total length: 300mm - Reduction rate: 49% - Wall thickness (thinning): -31.9% - Weight reduction: 18.2%

High-frequency heat treatment

High-frequency heat treatment

Partially harden. Optimal heat treatment with advanced technology.

Only the parts that require wear resistance can be hardened through surface hardening using electromagnetic induction. Due to rapid heating and rapid cooling, there is minimal oxidation and decarburization on the surface, and no thermal deformation occurs, resulting in excellent wear resistance. By changing the frequency, the depth of hardening can be adjusted, allowing for processing in a short time. Because very fast heating occurs, the know-how of skilled craftsmen is required. ● Heating coils suitable for the product shape are necessary. ● Detailed prior discussions will be conducted to perform heat treatment suitable for the material. ● Surface hardening allows the interior to remain as the original material while maintaining high toughness.

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

We have a wealth of accumulated technology in the field of processing techniques for reducing material costs, which is one of our strengths.

Carburizing and nitriding treatment refers to the process of simultaneously or continuously performing carburizing and nitriding. Generally, for materials with poor hardenability, such as low-carbon low-alloy steel, carburizing is conducted while adding ammonia gas or similar substances to achieve both carburizing and nitriding, aiming to improve the hardenability of the material at lower transformation temperatures. By performing nitriding, it becomes possible to effectively introduce hardness into materials that do not harden with carburizing alone. The quality characteristics obtained from carburizing and nitriding treatment include improved wear resistance and fatigue strength, similar to carburizing, as well as enhanced softening resistance. Recently, carburizing and nitriding treatment has also been applied to alloy steel or bearing steel for the purpose of improving mechanical properties. ● For more details, please contact us.
