[Production Example] SUS304

[Production Example] SUS304

Suitable for use in humid areas such as food/chemical industry equipment, machinery, faucets, and sinks!

We would like to introduce examples of processing SUS304 by our company. It is a material with very poor thermal conductivity, making it prone to tool breakage due to the difficulty in dissipating machining heat. Additionally, distortion of the stainless steel is likely to occur at high temperatures during processing, which is why it is considered a difficult-to-cut material. If excessive load is applied during processing, the structural organization changes, leading to work hardening, which is also a characteristic of this material. Therefore, the selection of cutting tools and how to manage heat during processing are key points in machining.

Duplex Stainless Steel

Duplex Stainless Steel

Introducing examples of duplex stainless steel products! We can manufacture from raw materials to finished products according to your needs.

We have a track record of supplying materials for paper manufacturing and bridge components that require corrosion resistance, and we are also capable of producing raw materials such as forged and rolled materials. We have a research facility in Muroran, where we can respond to various needs, including material development and proposals for optimal processes. For example, in ultra-thick duplex stainless steel, the cooling rate slows down, causing the σ phase to precipitate and reducing ductility and corrosion resistance. However, through our original component design, it is possible to suppress the σ phase. We also have various machining equipment, allowing us to deliver not only simple round bar and pipe shapes but also components and parts in the shapes required by our customers. *For more details, please refer to the PDF document or feel free to contact us.

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?

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.
