Low alloy heat-resisting steel for high temperature use |
摘要 |
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.
