First claim
Opening claim text (preview).
What is claimed is: 1. An iron golf club head comprising: a face portion and a neck portion integrally molded from a single material by forging, the single material being an iron steel material containing: less than or equal to 0.30% carbon by weight, 0.0005 to 0.003% boron by weight, 0.30 to 1.20% manganese by weight, and 0.01% to 0.05% titanium by weight said face portion having been subjected to quenching processing. 2. The iron golf club head according to claim 1 , further comprising; a cavity wall which surrounds the circumference of back side of the face portion, and the sole side cavity wall is undercut relative to the face normal direction. 3. The iron golf club head according to claim 1 , wherein the hardness of said face portion is HRC 25 or more, and the hardness of said neck portion is HRB 90 or less. 4. The iron golf club head according to claim 1 , wherein an undercut extending in a toe-heel direction of the iron golf club head comprises a formed pocket or machined slot. 5. The iron golf club head according to claim 4 , wherein minimum thickness of the undercut is 1.5 mm to 3.5 mm. 6. An iron golf club comprising: a golf club head comprising: a face portion and a neck portion integrally molded from a single material by forging, the single material being an iron steel material containing: less than or equal to 0.30% carbon by weight, 0.0005 to 0.003% boron by weight, 0.30 to 1.29% manganese by weight, and 0.01% to 0.05% titanium by weight, said face portion having been subjected to quenching processing.
