Introducing the properties and characteristics of stainless steel from spring trivia.
On this page, we introduce "Spring Trivia" from Sugawara Co., Ltd., which specializes in the design and manufacturing of special springs. Stainless steel means "rust-free," but more precisely, it is "rust-resistant" steel. When chromium is added to iron, it combines with oxygen to form a thin protective film on the surface of the steel. This film prevents the progression of rust. Its heat resistance is superior compared to piano wire, spring steel, and carbon tool steel. 【Characteristics of Stainless Steel】 ■ More precisely, it is "rust-resistant" steel ■ Chromium combines with oxygen to create a film on the surface of the steel that prevents rust progression ■ Superior heat resistance compared to piano wire, spring steel, and carbon tool steel *For more details, please refer to the PDF document or feel free to contact us.
