Material No.: 2.4617

EN symbol (short)NiMo28
Alloy B-2
UNSN 10665
AFNORNiMo 28
Registered work's labelHastelloy® B2
This material is an corrosion resistant alloy (nickel-molydenum-mixed crystal) with an checked minimum content of iron and chrome
excellent resistance against reducing substances, also against various organic acids
good resistance against hydrochloric acid in a wide range of concentrations and temperatures
2.4617 shows good resistance against corrosion due to tension and fissures
due to a low carbon and silicium content (which lowers carbide secretion in heated areas of weld seams) this material shows sufficient resistance against corrosion even in a welded state
