Abstract (en)
Cast metal parts such as turbocharger housings which are subject to operating temperatures up to about 2000 DEG F (1093 DEG C) and require good thermal cyclic durability (resistance to thermal cracking) and burst containment properties, are made from a low nickel duplex stainless steel with nitrogen addition by the use of grey and ductile iron casting technology.
