Super Duplex Stainless Steel ASTM A790 & ASTM A928 UNS S32750 WELDED AND SEAMLESS PIPE

S32750 Super Duplex Pipe have enhanced pitting and crevice corrosion resistance when compared with 300-series austenitic stainless steel or conventional duplex alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common “super” duplex grade.

UNS 31803 (F51), UNS 32205 (F60) Alloy 2205, UNS S32550 (F61), UNS S 32750 (F53), Alloy 2507 and UNS 32760 (F55)

Standards: ASTM/ASME A789/SA789, A790/SA790,A450,A530

Material: UNS S31803(Cr22Ni5Mo3/1.4462)/2205,UNS S32750(1.4410),UNS S31500(Cr18NiMo3Si2),

UNS32760(1.4501)

Usage of Duplex 2507 Pipe S32750 Stainless Steel:

It should be limited to applications below 6000 F (3160 C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion. The duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

S32750 Super Duplex Pipe possesses excellent mechanical properties. Often a light gauge of S32750 Stainless Steel can be used to achieve the same design strength of a thicker nickel alloy. The resulting saving in weight can reduce the overall cost of fabrication.
