VIRGO 17.4PH
Alloy VIRGO 17.4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions.
The grade combines high strength, hardness (up to 300°C / 572°F) and corrosion resistance. Mechanical properties can be optimised with heat treatment. Very high yield strength up to 1100-1300 MPa can be achieved.
The grade should not be used at temperatures above 300°C (572°F) or at very low temperatures. It has adequate resistance to atmospheric corrosion or in diluted acids or salts where its corrosion resistance is equivalent to CLC 18.9 (304) or SOLEIL B4 (430).
If there are potential risks of stress corrosion cracking, higher aging temperatures must be selected over 550°C (1022°F), preferably 590°C (1094°F).
The main applications are :
