    NiCr 70/30 (2.4658) waxaa loo isticmaalaa walxaha kuleylka korantada ee u adkeysiga daxalka ee foornooyinka warshadaha leh jawiga yareeya. Nickel Chrome 70/30 aad ayuu ugu adkaysanayaa oksaydhka hawada. Laguma talinayo in loo isticmaalo walxaha kuleyliyaha xiiran ee MgO, ama codsiyada la isticmaalayo nitrogen ama jawiyada carburizing.
