The welding wire used was SAF 2594. Their chemical compositions (w/%) are listed in Table 1. The mechanical and preparation methods used to achieve the welding parameters were described in detail elsewhere.5 2507 Coil can be applied in high corrosive applications where ordinary steel coils would not stand.
Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation. While the duplex-grade family includes a wide range of specific formulations, duplex S31803 (2205) and super duplex S32750 (2507) stainless steel are two of the most common. It is designed for welding similar composition steels e.g. SAF 2507, Uranus 52N, Zeron 100, which offer even higher strength and corrosion resistance levels than the ordinary duplex grades. Cromacore 2507 may also be used for welding standard duplex steels when higher corrosion resistance in the weld metal is required.

2507 acceptance criteria for plate ASTM A923. The data and information in this printed matter are believed to be reliable. 1993-09-07 · Abstract. The super duplex stainless steel SAF 2507, with a typical composition of ~25%Cr, 3·8%Mo, ~7%Ni, and 0·27%N, has been isothermally heat treated in the temperature range 700–1030°C for times between 1 min and 72 h. Super Duplex Steel also is known as SAF 2507 or Super Duplex 2507 with UNS S32750 and UNS S32760 (1.4410 / 1.4501 / F53 / F55 / 2507) is a high alloy duplex stainless steel with a PRE value of min.40*.
