Tips on Welding Materials: Characteristics of Austenitic Stainless Steel

Strong in low-temperature strength and toughness! Welding materials with a large coefficient of expansion and low thermal conductivity.

"Austenitic stainless steel" has excellent workability and weldability, and unlike other stainless steels, it is a non-magnetic welding material. Due to its sensitivity to stress corrosion cracking, care must be taken regarding stress concentration in welded areas. Additionally, craters are prone to cracking, so it is necessary to devise welding techniques such as crater treatment. In vacuum device components, having magnetic properties can be problematic, making this material optimal. 【Features】 - High coefficient of expansion and low thermal conductivity - Better weldability compared to martensitic, ferritic, and duplex stainless steels - SUS304 series has good weldability - Susceptibility to weld cracking is higher in materials with high nickel and molybdenum content, making them sensitive to hot cracking - Strong low-temperature strength and toughness For more details, please contact us.

A method to solve problems of rust and sharpness with stainless steel blades from the material level.

Focusing on stainless steel for cutting tools, we will introduce the "cutting" mechanism and more in a column!

Do you have any concerns about rust or dullness with your stainless steel tools (from knives to brush cutters and industrial blades)? It's disappointing when stainless steel (which means it doesn't rust) starts to show rust. When a blade doesn't perform as expected, it can be quite stressful. When a blade becomes dull, it requires extra force to cut, which can lead to accidents, making it dangerous. Unfortunately, no matter how expensive a stainless steel blade is, it will eventually rust or become dull with use. *For more details, you can view the related links.

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.

[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.
