HASTELLOY se yon alyaj nikèl-chromium-molybdène fòje ki konsidere kòm alyaj ki pi versatile ki reziste korozyon ki disponib.
Alyaj sa a se rezistan a fòmasyon nan fwontyè grenn presipite nan zòn nan chalè soude ki afekte, kidonk fè li apwopriye pou pifò aplikasyon pou pwosesis chimik nan yon kondisyon tankou soude.Fòm Hastelloy: Tiyo / Tib (soude ak san pwoblèm), Plak /Fèy, Bar, Fil, Fittings
