Abstract
The present invention provides low alloy steels having high strength and toughness, excellent high temperature creep rupture strength and ductility and low sensitivity to temper embrittlement. The alloy steel is a low carbon, low silicon-type Cr-Mo-V low alloy steel, to which are added aluminum, titanium, niobium and Zirconium individually or in combination and further, a small amount of boron.
