What is high-performance stainless "Silicoloy"? *High hardness × corrosion resistance

The balance of high Si and low C is characteristic! The composition of Ni, Cr, and precipitation strengthening elements is adjusted according to the application.

Generally, martensite in iron alloys that do not contain carbon is soft and highly ductile, but on the other hand, it has low strength, and since there is almost no carbon present even after tempering, carbide precipitation hardening is not achievable. Instead of carbides, fine precipitate particles of intermetallic compounds are dispersed to enhance strength, as seen in precipitation-hardened stainless steels such as SUS630 and SUS631, as well as ultra-high-strength maraging steels. Among silicoalloy steels, "Silicoalloy A2" and "Silicoalloy XVI" utilize the precipitation hardening mechanism, particularly characterized by the refined matrix structure of "Silicoalloy XVI," which has hard intermetallic compounds precipitating. For more details, please download and view the catalog. 【Precipitation-Hardened Silicoalloy】 ■ Silicoalloy A2 ■ Silicoalloy XVI *For more information, please refer to the PDF materials or feel free to contact us.

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.

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.
