Hastelloy® alloys dabere na alloys bụ ndị amaara maka nguzogide ha megide acid. Kacha nkịtị ndị bụ:

• Hastelloy® C-4, 2.4610 (Nickel balance, 14.5 - 17.5% Cr, 0 - 2% Co, 14 - 17% Mo, 0 - 3% Fe, 0 - 1% Mn): C-4 bụ nickel- chrome-molybdenum alloy nke etinyere na gburugburu ya na acid inorganic.
• Hastelloy® C-22, 2.4602 (Nickel balance, 20 -22.5% Cr, 0 - 2.5% Co, 12.5 - 14.5% Mo, 0 - 3% Fe, 0-0.5% Mn, 2.5 -3.5 W): C- 22 bụ ihe na-eguzogide ọgwụ na-eguzogide ọgwụ nickel-chrome-molybdenum-tungsten nke na-egosipụta ezigbo nnọgidesi ike megide acid.
• Hastelloy® C-2000, 2.4675 (Nickel balance, 23% Cr, 2% Co, 16% Mo, 3% Fe): A na-eji C-2000 eme ihe na gburugburu ya na oxidants na-eme ihe ike, dịka sulfuric acid na ferric chloride.

♦ Durakwalite ịdị ogologo oge nke ọrụ nickel

A na-eji alloys ndị nwere Nickel mara maka ezigbo akụrụngwa akụrụngwa dịka nkwụsị nke corrosion na nkwụsi ike dị elu. Kaosiladị, ihe fọrọ nke nta ka ọ bụrụ enweghị ọrụ ọ bụla nwere ike ịdịru mgbe ebighị ebi, n'agbanyeghị ka ihe si magburu onwe ya. Iji mee ka akụkụ nke ndụ dịkwuo ogologo, enwere ike iji alloys dabere na alloys na BoroCoat®, ọgwụgwọ anyị na-agbasa iji meziwanye nrụrụ na iyi mgbochi yana inye nkwụsi ike megide oxidants.

Mgbasa mgbasa nke BoroCoat® na-eme ka isi ike dị elu ruo 2600 HV ma na-ejigide oyi akwa nke 60 µm. A na-eme ka mgbochi ahụ dịkwuo mma, dịka nke pin na-egosi na nyocha diski. Ọ bụ ezie na omimi dị omimi nke alloys ndị na-enweghị ọgwụ nickel na-eme ka ogologo ntụtụ ahụ na-agbagharị, alloys ndị dabeere na BoroCoat® na-egosipụta ịdị omimi dị ala n'oge ule ahụ.
