HASTELLOY se yon alyaj nikèl-kromyòm-molibdèn ki fòje epi ki konsidere kòm alyaj ki pi versatile ki reziste korozyon ki disponib.
Alyaj sa a reziste fòmasyon presipite sou limit grenn nan zòn ki afekte pa chalè soude a, kidonk li apwopriye pou pifò aplikasyon pwosesis chimik nan yon kondisyon soude. Fòm Hastelloy: Tiyo / Tib (soude ak san pwoblèm), Plak / Fèy, Ba, Fil, Ekipman
Fil: 0.01-10mm
Bann: 0.05 * 5.0-5.0 * 250mm
