Basic Knowledge of Steel Materials: Stainless Steel Composition

Basic Knowledge of Steel Materials: Stainless Steel Composition

Stainless steel is an alloy primarily made of iron, mixed with chromium, nickel, and other elements.

Due to the presence of chromium and other elements, a strong passive film forms on the surface, making it a corrosion-resistant metal. Stainless steel is not a rust-proof steel; it is a "rust-resistant" steel. As chromium is added to iron, it gradually becomes more resistant to rust. When more than 10.5% chromium is added, it is referred to as stainless steel. In addition to corrosion resistance, stainless steel possesses excellent properties such as heat resistance, workability, and strength. It also excels in aesthetics and is easy to maintain, which are significant features. Furthermore, stainless steel has a long lifespan, resulting in less frequent repairs and replacements, providing advantages in terms of lifecycle costs.

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.

Strengthening Manual for Screws (Vol. 22) What is a passive state?

Strengthening Manual for Screws (Vol. 22) What is a passive state?

Introducing the reasons why stainless steel is resistant to rust in a blog format!

The reason stainless steel is resistant to rust is that "its surface is passivated." Now, what does this passivation mean? When chromium is added to iron, it combines with oxygen, meaning it oxidizes, and a thin protective film is formed on the surface of the steel. This phenomenon is called "passivation," and adding chromium in amounts of 10.5% or more is the condition for passivation to occur. The oxidized film that results from passivation is called the "passivation film," and this film prevents the progression of rust. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

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.
