Hastelloy ni aloi ya nickel-chromium-molybdenum ambayo inachukuliwa kuwa aloi ya sugu ya kutu inayopatikana zaidi.
Aloi hii ni sugu kwa malezi ya mipaka ya mipaka ya nafaka katika eneo lililoathiriwa na joto la weld, na hivyo kuifanya iweze kufaa kwa matumizi ya mchakato wa kemikali katika hali ya svetsade.Hastelloy fomu: bomba / tube (svetsade na mshono), sahani / karatasi, bar, waya, fittings: bomba (svetsade na mshono), sahani / karatasi, bar, waya, fittings: bomba (svetsade na mshono), sahani / karatasi, bar, waya, fittings: bomba (svetsade na mshono), sahani / karatasi, bar, waya, fittings
