Vascomax 250 Bar

Vascomax® 250 Bar is a vacuum induction melted and vacuum arc melted, low-carbon, nickel-cobalt-molybdenum high temperature alloy.

This Vascomax® 250 Bar can attain yield strengths in excess of 240 ksi (1655 MPa) through a simple, low temperature heat treatment. Vascomax® 250 Bar exhibits good ductility at high strength levels and is readily welded.

At Carey Alloys Metal Ind Pvt, we have many years of experience supplying Vascomax® 250 Bar forgings and many other product forms to your custom measurements and shapes. Our forging process includes open die forgings, ring rolling and more. See below for a list of the common C250 steel forged shapes and product forms we offer.
