Stainless Steel UNS S30403 Tubing

Stainless Steel UNS S30403 Tubing is a well-known material used to produce various industrial parts and components. This tubing consists mainly of Chromium, Nickel, Manganese, and Copper with smaller percentages of other elements such as Carbon, Silicon, Phosphorous, Sulfur, and Nitrogen added. This unique blend of metals gives the material its impressive corrosion resistance properties. Furthermore, the chromium content increases its hardness while the nickel helps maintain flexibility. The combination also leads to increased weldability and improved strength-to-weight ratio, making these tubes popular for diverse applications in aerospace, automotive, and power generation industries.
