A6928 VAR

The VAR 300M is a high quality aircraft grade low alloy Ni-Cr-Mo steel and contains vanadium and a higher silicon content compared to the 4340M to achieve even higher strength and higher tempering temperatures. The 300M is a through-hardening alloy. With its high transverse ductility, toughness and creep properties, the alloy is ideal for applications where strength and fatigue resistance together with impact strength and fracture toughness are paramount.
