Abstract

The invention discloses a stainless steel alloy for a golf ball head. The stainless steel alloy for the golf ball head is characterized by comprising the following components in weight percentages: 1-2% of manganese, 1-2% of silicon, less than 0.08% of carbon, 6-8% of nickel, 16-18% of chromium, 2-4% of copper, more than 0.2% of nitrogen, and the balance of iron. Hardness HRB (Rockwell hardness B-grade scale) value of the stainless steel alloy consisting of the components is 70-80. The stainless steel alloy is one type of stainless steel, is good in abrasive resistance, and has a better shocking-proof performance when being struck than stainless steel #304 or low carbon steel #8620, and the harness is HRB70-80. When struck at the same time, a golf ball and the ball head face have long contact time, the ball control performance is good, and the stainless steel alloy is applicable to a pull rod, an iron rod and a wedge. The stainless steel alloy has good hardness and abrasive resistance, the ball head is not easily deformed, and a groove of the ball face is difficult to abrade, so that the stainless steel alloy is an excellent golf ball head material.

Description

technical field [0001] The invention relates to a stainless steel alloy applied to golf heads Background technique [0002] The existing golf club head structure usually consists of a club head body and a striking faceplate which are welded or integrally formed. The striking faceplate is made of high-strength stainless steel alloy and processed by casting or rolling manufacture. Generally, the composition of stainless steel alloy is mainly composed of elements such as chromium, nickel, manganese, silicon, carbon, sulfur and phosphorus in an appropriate proportion, its specific gravity is about 8.0±0.5, and its hardness value HRB is about 89~95. Corrosion resistance, and its hardness value and other conditions are suitable for the relevant elements of golf heads. Therefore, most golf manufacturers currently make golf heads out of stainless steel. The golf head is assigned a fixed number due to different types, forms, angles, and uses. Each numbered ball head has a certain r...
