As shown in table 1, compared to the stainless steel of existing ASM 355 specifications and No. 2799602 similar ASM 355 specifications of United States Patent (USP), Stainless Steel Alloy of the present invention obviously has the silicon composition of high level, and additionally has the copper composition.Deck watch 1,2 and Fig. 1 and Fig. 2 are as can be known, and be as follows about the effect and the advantage of silicon of the present invention, copper, manganese, atmosphere and other each metal ingredients:
1, suitably to control the ratio of carbon be 0.08% to 0.15% in the present invention, so can increase solidity to corrosion, hardness and tensile strength;
2, suitably to control the ratio of silicon be 0.5% to 1.5% in the present invention, cast flowability in the time of not only can increasing melting, and help in ag(e)ing process carbide precipitate in the ferrite iron phase, so that make foundry goods can significantly improve tensile strength extremely greater than 200ksi (table 2 and Fig. 2), it is equivalent to roll and prolongs the formed tensile strength standard of sheet material, therefore be particularly conducive to the stress ability to bear that increases hitting panel, and then reduce its thickness requirement relatively.Textural at whole golf club head, by hitting panel subtract thick weight of saving with configurable to other positions of rod head noumenon, therefore also help turning down whole position of centre of gravity, and then increase the moment of inertia and the batting performance of bar head;
3, the present invention's ratio of suitably controlling manganese and nitrogen is respectively 0.4% to 1.2%, 0.07% to 0.13%, can promote the residual of austenite iron phase, strengthen the austenite iron phase, and during sub-zero treatment, make base material (matrix) be transformed into martensite iron (Fig. 3 a and 3b).This martensite iron can change tempered martensite iron once more into when ageing treatment.Therefore, can improve ductility, and then help casting the nargin (yardstick) of golf club head, the follow-up cover neck adjustment of increase angle, and improve the toughness of square stance:
4, suitably control below the ratio to 0.55% of copper, particularly 0.2% to 0.5%, help improving the effect of precipitation-hardening (precipitation hardening), it also helps increasing the tensile strength of Stainless Steel Alloy extremely greater than 200ksi (table 2 and Fig. 2);
5, suitably to control the ratio of nickel, chromium be 3.5% to 6.0% and 13.5% to 17.0% in the present invention, can suppress the generation that ripple comes iron (pearlite) tissue, with the rust resistance (being difficult for oxidation and rusting, pitting or even corrosion) that forms Stainless Steel Alloy itself;
6, suitably to control the ratio of molybdenum be 1.5% to 2.6% in the present invention, can keep a spot of strip ferrite iron phase (ferrite), to reduce the welding hot tearing susceptibility of Stainless Steel Alloy when welding, so that the hitting panel that casting is made has higher xenogenesis weld compatibility, and is applicable to welding assembly technology;
7, the present invention suitably controls below the ratio to 1.0% of vanadium, niobium, can be in order to mechanical properties and the weldability of improving Stainless Steel Alloy, and flowability and auxiliary degassing effect can effectively improve casting the time;
8, the present invention suitably controls below the ratio to 0.1% of sulphur, phosphorus, boron, so can reduce sunken the lacking of welding heat fragility (hot shortness) that sulphur, phosphorus, boron cause, to guarantee the welding quality of Stainless Steel Alloy.
As mentioned above, Stainless Steel Alloy material of the present invention is mainly has the martensite iron phase, the hitting panel that it can extend ringwall in order to the bar head (being golf club head) or the tool of casting integrated moulding.
This Stainless Steel Alloy utilizes compositions such as silicon, copper, manganese, nitrogen and controls its ratio, make the bar head or the hitting panel that make after appropriate heat treatment, have characteristics such as suitable high-tensile (＞200ksi, Ksi are unit of force), high castibility, high ductibility, high rust resistance (being difficult for oxidation and rusting, pitting or evenly corrosion), high weld compatibility and high mechanical properties.
Above-mentioned characteristic can reach following advantage:
1, when casting, this Stainless Steel Alloy has preferable flowability and plasticity, and its favourable minimizing produces the common defectives of casting such as cinder hole and pore;
2, because the Stainless Steel Alloy material has high-tensile, therefore help increasing the stress ability to bear of hitting panel, and then reduce its thickness relatively to 2.5mm, be preferably about 2.3mm.When the thickness of hitting panel or bar head reduces, also help making the ultra-large type golf club head;
3, by hitting panel subtract thick weight of saving with configurable to other positions of rod head noumenon, therefore also help turning down whole position of centre of gravity, and then increase the moment of inertia and the batting performance of bar head;
4, stainless copper alloy has moderate hardness and big slightly plasticity-, and therefore the cover neck of the bar head that makes can form bigger angle adjustable scope, and is easy to carry out angle modulation;
5, the solder bond that bar head that makes or hitting panel can carry out high-compatibility with the hitting panel or the bar head of unlike material is to satisfy variant production and user's demand.
