Si Hastelloy ay isang haluang metal na nakabase sa nikel na nakabatay sa nikel, na pangunahing nahahati sa dalawang kategorya: nickel-chromium alloy at nickel-chromium-molybdenum alloy. Ang Hastelloy ay may mahusay na paglaban sa kaagnasan at katatagan ng thermal, at kadalasang ginagamit sa aviation, kemikal na patlang, atbp.
Ernicrmo-4ay ginagamit para sa gas-tungsten-arc at gas-metal-arc welding ng Inconel alloy C-276 at iba pang nickel-chromium-molybdenum alloys. Dahil sa mataas na nilalaman ng molibdenum, ang haluang metal na ito ay nag -aalok ng mahusay na pagtutol sa pag -crack ng kaagnasan ng stress at pag -pitting at kaagnasan ng crevice.
