Abstract
The invention discloses an ultra-high-strength stainless steel, which comprises the following ingredients in percentage by weight: 0.5%-2% of aluminum, 9%-13% of chromium, 4%-5% of nickel, 2%-4% of molybdenum, 4%-6% of manganese, less than 0.09% of carbon, less than 0.8% of silicon, less than 0.025% of sulfur impurities, less than 0.025% of phosphorus impurities, and the balance of ferrum and inevitable impurities. The ultra-high-strength stainless steel disclosed by the invention has excellent comprehensive mechanical properties, and is applied to the striking surface of a golf club head to reduce the thickness of the striking surface and improve the weight distribution state of the golf club head so as to improve the ball hitting performance of a ball arm.
Description
Technical field
The present invention relates to the ultrahigh-strength steel technical field, relate in particular to a kind of superhigh strength stainless steel and the application aspect golf club thereof.
Background technology
Superhigh strength stainless steel is mainly used in aerospace senior precision machinery at present, as high-load load parts, High Pressure Shell etc., application in the golf club field is mainly some PH Stainless Steel such as 17-4PH, 15-5PH, has resistance to corrosion, its intensity does not surpass 1500Mpa, toughness is very not high yet, the superhigh strength stainless steel intensity of patent of the present invention can reach the 1800Mpa left and right, toughness also can satisfy the service requirements of golf club simultaneously, can effectively improve the batting performance of club, can promote the use of in art of golf.
Summary of the invention
The invention discloses a kind of superhigh strength stainless steel, described superhigh strength stainless steel contains by weight percentage: aluminium 0.5-2%, chromium 9-13%, nickel 4-5%, molybdenum 2-4%, manganese 4-6%, carbon is less than 0.09%, silicon is less than 0.8%, and sulphur, phosphorus impurities content are all less than 0.025%, and all the other are iron and inevitable impurity.Superhigh strength stainless steel of the present invention has good comprehensive mechanical property, and its application aspect the golf club scope of attack is the thickness of the attenuate scope of attack significantly, improves the weight distribution state of club head, thereby improves the batting performance of club.
Superhigh strength stainless steel of the present invention adopts intermediate frequency vacuum induction melting electrode.Get the composition in stove sample analysis smelting process, control adjustment by design objective, pour into electrode bar, carry out vacuum arc remelting.Heating steel billet to 1150 ± 20 ℃ are forged into slab.Through hot rolling, cold rolling, after timeliness thermal treatment in 550 ℃ * 2 hours, the intensity of sheet material can reach 1800Mpa, and unit elongation can reach 7%.
Superhigh strength stainless steel sheet material of the present invention is applied on the scope of attack of golf club, thickness that can the attenuate scope of attack reduces the weight of the scope of attack, the center of gravity of bulb can be moved down backward in the design of bulb like this, change the bulb weight distribution, thereby improve the batting performance of club.
Embodiment
Embodiment 1
Adopt vacuum induction melting, specifically by ingredient composition of the present invention, the weight percent of alloy consists of: aluminium 0.5-2%, chromium 9-13%, nickel 4-5%, molybdenum 2-4%, manganese 4-6% controls carbon less than 0.09%, silicon is less than 0.8%, and sulphur, phosphorus impurities content water into electrode all less than 0.025%.Carry out subsequently vacuum arc remelting.Heating steel billet to 1150 ± 20 ℃ are forged into slab.Through hot rolling, cold rolling, make desired thickness sheet material after timeliness thermal treatment in 550 ℃ * 2 hours.
With the stainless steel plate (thickness is 2.5mm) that makes after tested, the mechanical property under room temperature such as following table 1.1
Table 1.1 superhigh strength stainless steel room-temperature mechanical property of the present invention
| The sampling direction | Yield strength (MPa) | Tensile strength (MPa) | Elongation (%) |
| Vertically roll to | 1798 | 1625 | 7.0 |
After being cut into the required shape welding of the golf club scope of attack, stainless steel materials of the present invention makes bulb, the thickness of the scope of attack can reduce 1/3, weight can alleviate tens grams, and the center of gravity that can adjust in design like this bulb moves downwards backward, has improved the batting performance of club.
