AISI 302 stainless steel drawn wire for spring manufacturing by Demasteel

When it comes to wire springs, it's crucial to use a material which is both strong, durable, and easy to work with. That's why the choice often falls on AISI 302 stainless steel wire. In this article, the renowned steel wire supplier Demasteel goes over the reasons that make AISI 302 stainless steel wire highly popular among spring manufacturers. 

AISI 302, also known as type 302 steel, is a versatile material. The "AISI 302" designation comes from the American Iron and Steel Institute (AISI) classification. Specifically, it is an austenitic stainless steel alloy with a high chromium or chromium-nickel content, possessing excellent mechanical properties for cold forming processes such as spring forming.

AISI 302 stainless steel: chemical composition, characteristics, and advantages in spring manufacturing

Corrosion resistance: stainless steel wire is renowned for its ability to resist both atmospheric elements and aggressive chemical compounds, making it highly durable. These mechanical characteristics are achieved thanks to its high chromium content, creating a protective oxide layer on the surface, known as a passive layer.

Easy to process: another fundamental aspect contributing to the popularity of stainless steel wire among spring manufacturers is that it is easy to process. It means that springs of various shapes and sizes, including custom ones, can be easily formed.

High tensile and fatigue strength: stainless steel springs often face variable and cyclic loads. AISI 302 steel, in particular, is known for its high tensile and fatigue strength, ensuring that springs maintain their performance over time even in intensive usage scenarios.

Aesthetics: in addition to technical qualities, stainless steel can be easily polished to achieve a smooth and shiny surface, giving springs an aesthetically pleasing appearance.

Applications of AISI 302 stainless steel springs

The choice of steel type plays a crucial role in manufacturing industries, as applications can vary significantly in terms of specific needs and requirements. Among the various materials available, AISI 302 steel stands out as a strong choice in various industrial sectors, such as automotive, electronics, and aerospace industries, which often rely on these types of springs for their afore-mentioned properties.
