Duplex/ Super Duplex Round Bar

Duplex/Super Duplex Stainless Steel Round Bars are a superior choice for demanding applications requiring exceptional corrosion resistance, high strength, and good weldability. They offer significant advantages over traditional austenitic stainless steels.

**Description:**

Duplex and Super Duplex grades provide superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to 304/316 stainless steels, making them ideal for harsher environments like seawater or chloride-rich applications. These bars possess higher mechanical strength than typical austenitic steels, allowing for thinner sections in some designs while maintaining structural integrity. Duplex/Super Duplex grades offer good weldability compared to other high-strength stainless steels, minimizing the risk of weld cracking.
