UNS N10675 Hastelloy B3 Pipe OD 1/2" - 48" SCH 5 - SCH XXS Beveled End ASTM B474
1.Hastelloy B3 description
Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion,
and stress-corrosion cracking plus, thermal stability superior to that of alloy B-2. In addition,
this nickel steel alloy has great resistance to knife-line and heat–affected zone attack. Alloy B-3
also withstands sulfuric, acetic, formic and phosphoric acids, and other non-oxidizing media.
Furthermore, this nickel alloy has excellent resistance to hydrochloric acid at all concentrations
and temperatures. Hastelloy B-3’s distinguishing feature is its ability to maintain excellent
ductility during transient exposures to intermediate temperatures. Such exposures are routinely
experienced during heat treatments associated with fabrication.

2.What is ASTM B474
This specification covers electric fusion welded pipe suitable for high-temperature or corrosive service.
The pipes are designated into five classes namely Class 1, Class 2, Class 3, Class 4 and Class 5,
according to how they are to be welded. The joints shall be full penetration double-welded or single-
welded butt joints employing fusion welding processes. The furnished pipe shall undergo heat treatment
and a chemical analysis shall be employed for both plate and weld. Each pipe shall be subjected to
transverse tension test, transverse guided weld bend test and hydrostatic pressure test.
