Description of the invention (3), so that the aforementioned molten alloy molten steel is in this ceramic mold Good flow, can prevent segregation, and prevent cracks and fissures in the solidified pieces. Therefore, various sickle components (such as golf club iron heads, metal club heads, panels, etc.) can be obtained by pouring by TIG welding with a welding current of 40 to 60 amps, which can prevent the vicinity of the bead. There are cracks or crevices and pinhole patterns, so the solid solution oil quenching of the welded sickle at 800 ~ 900¾, 45 ~ 60min can increase the oxidation resistance of the surface of the sickle. After 250 ~ 350¾, 1 ~ 2hr aging treatment can obtain high hardness and strength pieces.

Description of the invention (8) Known from Table 1 The golf metal club head 1 made of the precision insert of the ultra-high-strength alloy steel (300M) invented is compared with the golf metal club head made of conventional stainless steel (17-4PH) ft, which can be obtained by the present invention. Know the alloy characteristics of ultra-high-strength alloy steel (300M)-high hardness, high strength and mechanical strength, at the same time, it can produce light weight, superior shock absorption, low impact sound, distance from the ball, and excellent golf stability. Ball metal club head. In addition, after the paint treatment, the golf ball metal club head 1 was also found to have a corrosion resistance of 24 hours in the 5¾ 塩 fog test. 搿 明: > The power amplifier according to the present invention High-strength alloy steel precision sickle made of golf metal stalk heads, which are pre-regulated to form carbon (C) 0.35 to 0.45% by weight, silicon (Si) 1.5 to 2.6 weight SK, nickel (Ni ) 1.6 to 2.0 weight! ", Chromium (Cr) 0.6 to 0.8% by weight, molybdenum (Mo) 0.2 to 0.4% by weight, vanadium (V) 0.15 to 0.45% by weight 3; and alloy raw materials with a residual content of iron (Fe) quickly The heat is melted to 1600 ~ 1,700Ό, and it is preheated to 1200 ~ 1300¾ in the ceramic mold, so that The molten alloy molten steel flows well in this ceramic mold, which can prevent segregation and prevent cracks and cracks in the solidification of the paving. Therefore, various sickle components obtained by pouring sickle use welding current of 40 ~ 60 Ampere's TIG welding method can prevent cracks or cracks and pinholes near the weld bead. Therefore, the solidified oil quenching of the welded pieces at $ 00 ~ 9 00 1C, 4 5 ~ 60min can inhibit the formation of oxide layer on the surface of the gong piece, and then subject to 250 ~ 350 ° C, 1 ~ 2hr aging tempering treatment. High-strength sickle pieces are available. From these facts, it can be known that the ultra-high-strength alloy steel with high wear resistance and wear resistance that has high toughness, high mechanical strength, and excellent endurance is less harmful to nickel.
