Abstract

The invention discloses an iron-based low-density golf club head stainless steel alloy and a manufacturing method of same. The alloy is used for an iron club head and includes, by weight, 17.5-18.8% of Cr, 9.5-10.5% of Mn, 2.5-3.6% of Ni, 1.5-2.5% of Si, 0.05-0.09% of C, and the balanced being Fe and other unavoidable micro-scale alloy elements. The alloy has corrosion resistance and high elongation rate and is 7.42-7.62 g/cm<3> in density [rho], so that the design space of the golf club head is increased. The alloy, after solution treatment at 1050 +/- 50 DEG C for 1-2 h, is free of any aging treatment subsequently. The alloy has a biphase structural organization of ferrite [alpha] + austenite [gamma], wherein the ratio of [alpha] is 25-40%; the alloy is 630-900 MPa in extension strength, is 420-600 MPa in yield strength and has high extension ratio being 40-55%, and also has corrosion resistance in an anti-salt fog test (NaCl).

Description

technical field [0001] The present invention relates to an alloy structure: it has a two-phase structure of ferrite (α)+Worth field iron (γ), the ratio of ferrite (α) is between (5% and 40%), and the yield strength is between Between 420-600MPa, high elongation (40-55%), corrosion resistance, and density between ρ=7.42~7.62g / cm 3 , particularly with regard to an alloy that increases the design space of golf iron club heads. Background technique [0002] Golf is a sport that uses a club to hit a ball into a hole. The basic rule is to tee off the golf ball at the teeing position, overcome various natural or artificial obstacles, and push the ball into a specific hole on the green. Inside, the number of strokes used will be counted. There are a total of 18 holes in a game (par 72), and the player with the lowest cumulative total score will be the winner. [0003] A complete set of golf clubs should not exceed 14 pieces at most. According to the needs of the course and differe...
