ULTRA-HIGH STRENGTH STAINLESS ALLOY STRIP, A METHOD OF MAKING SAME, AND A METHOD OF USING SAME FOR MAKING A GOLF CLUB HEAD

摘要

A stainless steel strip article is disclosed. The article is formed from a corrosion resistant alloy having the following composition in weight percent, C 0.03 max. Mn 1.0 max. Si 0.75 max. P 0.040 max. S 0.020 max. Cr 10.9-11.1 Ni 10.9-11.1 Mo 0.9-1.1 Ti 1.5-1.6 Al 0.25 max. Nb 0.7-0.8 Cu 1 max. B 0.010 max. N 0.030 max. The balance is iron and usual impurities. The elongated thin strip article provides a room temperature tensile strength of at least 280 ksi (1930.5 MPa) in the solution treated and age hardened condition. A method of making the strip article and a method of using it to make a golf club are also disclosed.
