Abstract
An alloy of a golf club comprises 0.25 wt % to 1.0 wt % Si, 0.25 wt % to 1.5 wt % Mn, 2.0 wt % to 3.5 wt % Cu, 6.0 wt % to 8.0 wt % Ni, 15.5 wt % to 18.0 wt % Cr, balance iron and inevitable impurities, wherein the alloy of a golf club has austenite structures, ferrite structures, and martensite structures simultaneously.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . An alloy of a golf club comprising:
0.25 wt % to 1.0 wt % Si; 0.25 wt % to 1.5 wt % Mn; 2.0 wt % to 3.5 wt % Cu; 6.0 wt % to 8.0 wt % Ni; 15.5 wt % to 18.0 wt % Cr; and balance iron and inevitable impurities, wherein the alloy of a golf club has austenite structures, ferrite structures, and martensite structures.
2 . The alloy of a golf club as claimed in claim 1 , wherein Ni is in a range of 6.5 wt % to 8.0 wt %.
3 . The alloy of a golf club as claimed in claim 1 , wherein Si is in a range of 0.5 wt % to 1.0 wt %.
4 . The alloy of a golf club as claimed in claim 1 , wherein Mn is in a range of 0.5 wt % to 1.5 wt %.
5 . The alloy of a golf club as claimed in claim 1 , wherein Cu is in a range of 2.5 wt % to 3.5 wt %.
6 . The alloy of a golf club as claimed in claim 1 , wherein Cr is in a range of 16.0 wt % to 17.5 wt %.
