Features and Applications
- The sum of the Cr + 3.3 (Mo + 0.5 W) + 16 N, known as the Pitting Resistance Equivalent Number (PREN), is at least 40, thereby allowing the weld metal to be called a “super-duplex stainless steel.” This number is a semi-quantitative indicator of resistance to pitting in aqueous chloride-containing environments.
- It is designed for the welding of Type 2507 superduplex stainless steels UNS S32750 (wrought) and UNS J93404 (cast), and similar compositions.
- Re-drying : 250-300°C / min. 2h
Current Type
- DC(+)
