HastelloyB-3 Material introduction

HastelloyB-3（UNS N10675/NS323）Alloy is a new member of Ni Mo alloy family, which has excellent corrosion resistance. Moreover, due to the adjustment of its chemical composition, its thermal stability has been greatly improved compared with the original Hastelloy B-2 alloy. Hastelloy B-3 alloy has high resistance to spot corrosion, stress corrosion cracking, knife like corrosion and corrosion in heat affected zone of welding.
