duplex stainless steel tubing Dimensional Range & Standard Specification
Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades, and have improved resistance to localised corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades which means we can use it to design thinner gauge tubing. Higher hardness values provide better wear resistance for high precision tubes.
Duplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex. This family of alloys has great advantages in both material and engineered fabrication costs.
We offer duplex stainless steel tubes in the following alloys:
| Alloy | UNS | WNR |
|---|---|---|
| Duplex | S31803 | 1.4462 |
| Super Duplex | S32750 | 1.441 |
| Super Duplex | S32760 | 1.4501 |
