The reason you use stainless steel.

The reason you use stainless steel.

The immobile film is thin, stable, and self-repairing! We will introduce its fascinating history of creation!

Stainless steel is a metal that is made by adding elements such as carbon (C) to iron (Fe). Specifically, stainless steel is a type of steel that contains more than 10.5% chromium (Cr) and less than 1.2% carbon (C). Alternatively, one could simply say that stainless steel is iron that is resistant to rust and corrosion. In fact, there is another answer. Stainless steel is a metal that is rich in functionality and convenience. While stainless steel is now a common metal found everywhere, understanding its true nature reveals why it has become an indispensable material in the world. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us or check the PDF materials.*

Non-magnetic stainless steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

Non-magnetic stainless steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

It is stainless steel that can maintain non-magnetic properties even after processing! We will propose steel grades according to your usage conditions, such as the required level of non-magnetism.

SUS304, a representative type of austenitic stainless steel, is non-magnetic in its solution-treated state, but it becomes magnetic (more likely to be attracted to magnets) due to martensitic transformation during cold working. Therefore, there have been challenges such as the need to keep the processing rate low to maintain non-magnetism or sacrificing strength. Non-magnetic stainless steel is a type of steel that has been adjusted so that martensite is not induced (or is less likely to be induced) during cold working, allowing it to maintain non-magnetism even after processing. We can recommend types of steel based on your usage conditions, such as processing methods and required levels of non-magnetism.

Precipitation Hardening Stainless Steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

Precipitation Hardening Stainless Steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

It is a material that has corrosion resistance as stainless steel while enhancing strength! We will propose steel types according to your application and processing methods.

Precipitation-hardened stainless steel is a material that possesses corrosion resistance as a stainless steel while utilizing precipitation hardening (aging) to enhance its strength. Particularly in the case of SUS631, in the annealed (solution heat-treated) state, it has a soft, metastable austenitic phase, allowing it to withstand complex processing similar to austenitic stainless steels. Additionally, by inducing precipitation hardening (heat treatment) after processing, it is possible to improve strength, achieving a combination of workability and high strength through heat treatment. Our company handles three types: SUS631 (17-7PH), SUS632J1 (15-7PH), and TOKKIN 350, and we can suggest steel types according to your applications and processing methods. *1 The general corrosion resistance ranking by system is austenitic > precipitation-hardened > ferritic. *2 Precipitation hardening refers to the artificial aging treatment performed after solution heat treatment, with the stainless steels in the 600 series and maraging steels introduced on this page being representative examples. For more details, please refer to the related links or feel free to contact us.

Heat-treated stainless steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

Heat-treated stainless steel [TOKUSHU KINZOKU EXCEL CO., LTD.]

This is heat-treated stainless steel. It is recommended for customers seeking the unique properties and hardness of stainless steel, as well as high quality!

Unlike carbon steel, which hardens through heat treatment, there are few materials that harden in this way, limited to precipitation hardening systems and medium to high carbon chromium stainless steels. Martensitic stainless steel, while being a type of stainless steel, has a higher carbon content, allowing it to be hardened significantly through quenching and tempering, similar to carbon steel. Most customers who use this material after quenching apply heat treatment after forming it into various products. However, in recent years, advancements in processing equipment and techniques aimed at rationalization have made it possible to produce efficient products with minimal variation, even from extremely hard materials like hardened steel strips and quenched steel strips, through continuous pressing or cutting. As a result, heat treatment after processing the product has become complicated in terms of quality control and work management, leading to lower productivity. Consequently, there is a growing trend to switch from quenching after forming to using pre-hardened steel strips. Our company responds to the needs of customers seeking the unique properties and hardness of stainless steel, as well as high quality, by providing pre-hardened stainless steel strips. *The quenching process for SUS420J2 is primarily conducted at our Shanghai factory. For more details, please refer to the related links or feel free to contact us.

[Production Example] Processing of SUS304

[Production Example] Processing of SUS304

The key point in processing SUS304 is how to minimize heat during the selection and machining of cutting tools.

At Shin-Ei Manufacturing Co., Ltd., we handle the processing of SUS304. SUS304 is a stainless steel material that excels in corrosion resistance and heat resistance, and it is the most commonly used stainless steel with the highest production volume. It is an alloy of iron with 18% chromium and 8% nickel, and due to its low carbon content, it has excellent corrosion resistance and weldability, making it widely used as a high-grade stainless steel. Additionally, SUS304L is an ultra-low carbon steel that has reduced carbon content compared to SUS304 and is used for parts that cannot undergo heat treatment after welding due to its excellent resistance to intergranular corrosion. Please feel free to contact us if you have any requests. [Overview] ■ Corrosion resistance ■ Heat resistance ■ Excellent intergranular corrosion resistance *For more details, please download the PDF or feel free to contact us.

Black Decorative Stainless Steel Fine Black

Black Decorative Stainless Steel Fine Black

Stainless steel that achieves a metallic feel and deep black color.

1. Natural coloring Unlike coloring with dyes or pigments, fading due to ultraviolet rays does not occur at all. Weather resistance is also good. 2. Transparent film Since the coloring is due to a thin transparent oxide film, a color tone that utilizes the metallic feel of stainless steel can be achieved. 3. Corrosion resistance and wear resistance The surface is treated with a special hard film process (hardening), providing excellent corrosion and wear resistance. 4. Workability Because the coloring is due to a thin oxide film, adhesion is good, allowing for bending and light pressing processes. 5. Heat resistance Discoloration is not observed up to 300°C in the atmosphere. 6. Environmental impact Since no dyes or pigments are used, the contained substances are the same as those in general stainless steel, allowing for similar recycling.
