Difficult-to-cut material processing examples: Stainless steel (SUS)

Difficult-to-cut material processing examples: Stainless steel (SUS)

It excels in acid resistance and heat resistance, and is used in various fields, with a very wide range of applications!

"Stainless steel (SUS)" is an alloy steel that contains chromium (Cr) or a combination of chromium and nickel (Ni) to enhance corrosion resistance. Compared to ordinary steel, it excels in corrosion resistance, oxidation resistance, and heat resistance, making it widely used in various fields such as tableware, kitchen utensils, civil engineering and construction materials, medical devices, and aerospace components. Generally, it has lower thermal conductivity, greater ductility, and a higher work hardening rate compared to ordinary steel. As a result, it is considered difficult to machine due to reasons such as shorter tool life and the hardness of chips, which makes them difficult to break. [Features] - Superior in corrosion resistance, oxidation resistance, and heat resistance compared to ordinary steel - Lower thermal conductivity compared to ordinary steel - Greater ductility and higher work hardening rate - Shorter tool life and chips that are hard and difficult to break *For more details, please refer to the PDF document or feel free to contact us.

High-quality ferritic stainless steel "FS-1" [Special Metal Excel]

High-quality ferritic stainless steel "FS-1" [Special Metal Excel]

Ferritic stainless steel with a nickel content of 1%. This material has improved corrosion resistance and strength compared to SUS430.

FS-1 is a unique steel grade developed by our company, which is a ferritic stainless steel that incorporates nickel (Ni) into the representative steel grade SUS430. This allows it to maintain the characteristics of ferritic stainless steel while providing a certain level of strength and corrosion resistance. It can also be used as an alternative to SUS304, which is commonly used in general environments. The main features of FS-1 are as follows: (1) Formability superior to SUS430 FS-1 has sufficient formability compared to SUS430, allowing for high-precision press processing without causing wrinkling. (2) Strength equivalent to SUS304 FS-1 can achieve full hardness with a hardness of HV330 and tensile strength of 1100 MPa (equivalent to the strength of SUS304-3/4H). (3) Minimal impact from fluctuations in nickel prices With a nickel content of only 1%, FS-1 is largely unaffected by fluctuations in nickel prices, enabling stable cost management.

Tōroku Fire-Made Stainless Steel

Tōroku Fire-Made Stainless Steel

Hitting a chisel and driving a nail, it's precisely because they are simple tools that they have great depth.

It is resistant to rust and less prone to dirt, making it perfect for tasks that dislike dirt, such as interior work. Although the hardness after quenching is slightly lower due to the material properties compared to general steel (S55C), it possesses a strong toughness, allowing it to withstand professional heavy use.

【Spring Trivia】About SUS631-CP and SUS631-CSP

【Spring Trivia】About SUS631-CP and SUS631-CSP

Introducing some trivia about springs! Our company uses SUS631-CP material instead of O material.

The JIS standard heat treatment symbol for SUS631-CSP includes four types: O material for solution heat treatment finish, and 1/2H, 3/4H, and H for cold-rolled finish. However, due to the lack of availability of O material, our company uses SUS631-CP material instead. The chemical composition and mechanical properties of SUS631-CP and SUS631-CSPO materials are the same, but there are differences in plate thickness tolerance and manufacturing processes. The characteristic of SUS631, similar to wire, is that its tensile strength and hardness increase due to precipitation hardening heat treatment (because the added aluminum precipitates), but the conditions differ from those of wire (air-cooled after heating at 470±10°C for 1 hour). For more details, please refer to the related links. 【SUS631-CSP Heat Treatment Conditions】 ■Heat Treatment Name: CH ・Air-cooled after heating at 470±10°C for 1 hour *For more details, please refer to the PDF document or feel free to contact us.

[Material Improvement Case] From Material Selection to Reduction of Processing Time

[Material Improvement Case] From Material Selection to Reduction of Processing Time

Introduction of case studies on the selection of materials such as stainless steel, aluminum, and brass, and the reduction of processing time.

Here is a case study on "Material selection and reduction of processing time." 《Customer's Challenge》 The material needs to be corrosion-resistant, so stainless steel is preferred. The delivery time is urgent. 《Solution》 SUS304 is the most commonly used stainless steel, but we recommend SUS303. Compared to 304, it has better machinability, which can reduce processing time. 【Product Description】 ■ SUS303 contains sulfur (S) and phosphorus (P), which are elements that enhance machinability. ■ If welding is required, SUS304 will be used. ■ In addition to stainless steel, we can also process aluminum, brass, copper, iron, and plastics. For more details, please refer to the catalog or feel free to contact us.
