KLEINOX 4614 – CUSTOM 465 – UNS S46500 – ASTM F899, A564, AMS 5936

USES AND APPLICATIONS

KLEINOX 4614 is a premium precipitation hardening martensitic stainless steel. This VIM / VAR melted and remelted steel has been designed to provide in the cold worked and H900 aged a UTS up to 2090 MPa, with an excellent tensile notch resistance coupled to a high toughness. In the H1000 condition it has a most favorable combination of high strength, stress corrosion resistance and toughness. This steel is well indicated for the production of surgical, chemical, pharmaceutical and agro food instruments.
