Embodiment Construction

[0008] A preferred embodiment of the stainless steel composition alloy of the golf club head of the present invention comprises 0.03wt% carbon, 0.01wt% phosphorus, 0.1wt% silicon, 0.05wt% calcium, 0.03wt% zirconium, 0.1wt% manganese, 0.01wt% sulfur, 4wt%~5.1wt% molybdenum, 18wt%~19wt% nickel, 7~12wt% cobalt, 0.05wt%~0.15wt% aluminum, 0.1wt%~0.8wt% titanium, and iron for balance and not zero.

[0009] In addition to the precipitation of carbides, carbon is also an element in the stable phase of Worsfield iron. As the carbon content increases, the fertilized iron decreases and the Worsfield iron becomes more stable. Silicon has the characteristics of preventing the formation of pores in the alloy material, promoting shrinkage and increasing the fluidity of molten steel. Therefore, adding 0.1wt% silicon to the alloy material of the present invention will help the process of casting raw materials.

[0010] Titanium and carbon elements are easy to form stable carbides, which can ...

Abstract

The invention discloses stainless steel alloy for a golf club head. The stainless steel alloy contains 0.03wt% of carbon, 0.01wt% of phosphorus, 0.1wt% of silicon, 0.05wt% of calcium, 0.03wt% of zirconium, 0.1wt% of manganese, 0.01wt% of sulfur, 4wt% to 5.1wt% of molybdenum, 18wt% to 19wt% of nickel, 7wt% to 12wt% of cobalt, 0.05wt% to 0.15wt% of aluminum, 0.1wt% to 0.8wt% of titanium and iron which is used for balance and has a content larger than 0. The silicon element substance is used for improving the mobility of the alloy in a liquid state; by cooperation of the titanium and the molybdenum, the mechanical properties of the alloy are improved; by adding the aluminum to stabilize the ductility of the alloy, the ductility of the alloy is not greatly reduced due to enhancement of the strength, so that a golf club head which is more excellent in strength and wear resistance in comparison with a golf club head prepared from existing alloy can be manufactured at a relatively low manufacturing cost.

Description

technical field [0001] The present invention relates to an alloy, in particular to a stainless steel composition alloy of a golf club head. Background technique [0002] Golf is to drive the club by twisting the waist and swinging the club, and use the club head to hit the golf ball. Therefore, the golf club head must have high strength, In addition to high wear resistance, it must also have characteristics such as light weight to prevent players from getting too tired, and high stability to make the golf ball travel when hit. In addition, it is necessary to take into account the difficulty of the molding preparation process, so as to avoid many problems such as the finished product being unacceptable by the market due to the price factor due to the increase in cost. Therefore, the development of new materials, especially different compositional alloys, in order to prepare golf club heads with various characteristics is the most labor-intensive and cost-intensive R&D work i...
