Answer 1

Answer:

between 550 and 800 MPa

Explanation:

Cobalt-chromium alloys

The hardness of Co-Cr alloys ranges between 550 and 800 MPa, and tensile strength ranges between 145 and 270 MPa. Moreover, the tensile and fatigue strength increases radically as they are heat-treated. These alloys have properties quite similar to stainless steel
