Nickel Alloy 2.4889 1/2H vs 2.4889-H

Nickel Alloy · 2.4889 temper comparison

2.4889 1/2H and 2.4889-H are two conditions of the same nickel alloy grade, 2.4889: 1/2H (half hard) versus H (hardened). The chemistry is identical, so every difference below comes from the condition. 2.4889-H is the stronger of the two: yield strength 950 MPa (138 ksi) against 700 MPa (102 ksi) for 2.4889 1/2H, about 36% more; tensile strength follows at 1,150 MPa (167 ksi) vs 950 MPa (138 ksi). In exchange, 2.4889 1/2H is the more ductile: elongation 15% versus 4% for 2.4889-H, and 2.4889-H is harder (300 HB vs 235 HB).
