Abstract
PURPOSE: To obtain the captioned steel capable of processing uniform photo-etching even after welding and aging, by containing toughness and hardenablility improving components such as Cr and W in addition to the basic components such as C, Si, Mn, Ni, and Al.
CONSTITUTION: The steel containing C; 0.05 to 0.18%, Si; 0.15 to 1%, Mn; 1 to 2%, Ni; 2.5 to 3.5%, Al; 0.5%, Cu; 0.7 to 1.7%, Mo; 0.1 to 0.4%, and Fe for the rest, which are basic components, and also containig one or both additives, i.e. toughness and hardenability improving alloy component (a) and granulation promoting alloy component (b), which presents similar characteristics as the base metal in the deposited steel and welding heat affected zone even when aged after welding. Said additives are a) Cr; 0.21 to 2.5%, W; less than 0.5%, Co; less than 0.5%, Be; less than 0.5%, and B; less than 0.01%, of which more than one kind, b) Ti; less than 0.5%, V; less than 0.5%, Nb+Ta; less than 0.3%, and Zr; less than 0.5%, of which more than one kind.
