Abstract
The invention discloses a kind of free-machining chromium stainless steel for ball pen head, it is characterized in that: matrix is Fe, and the percentage composition of all the other components is: C :≤0.03, and Si≤1.00, Mn≤2.00,0.15≤S≤0.5, P≤0.05, Cr19-21, Mo1.5-2.5, Pb0.10-030, Te0.01-0.07; O 〉=50ppm wherein in addition.This stainless steel has corrosion resistant, anti-corrosion wear performance and good free cutting property, is suitable for turning and makes ball pen head.
Description
Technical field
The invention belongs to a kind of material of ball pen head, specifically is a kind of free-machining chromium stainless steel for ball pen head.
Background technology
According to China ballpoint pen standard GB/T4306 and GB/T1655 regulation, that China's ballpoint pen is divided into is senior, middle rank and common three class, and by used ink performance difference, is divided into five kinds such as oiliness, water-based, pressure, ball and erasable type.
The major parts of ballpoint pen has that pen is done, pen core and oil (water) China ink, wherein pen core is made up of five parts such as ball, ball seat body, oil pipe, printing ink and floating plugs, it utilizes the slip of little ball in the Metal Ball pedestal on the nib, adheres to and carry that oil (water) China ink is transferred to paper surface and the function of finishing written record.
The ball of ballpoint pen, past usefulness be stainless steel, all use carboloy at present, uniform micropore because its surface hardness height, wear-resisting, corrosion-resistant, surface gather, make ball be convenient to adsorb ink, reach China ink evenly, svelteness, write smoothly and purpose that feel is comfortable.
The circle of ball is just being spent tolerance≤0.001mm, and tolerance of dimension is-0.002mm, surface smoothness 〉=10 grade.The structure of ball seat body comprise ball seat, annular groove, straight trough, little oilhole and in oilhole, the quality of fit on ball and ball seat surface, machining precision, assembly precision are more taller than the precision of clock and watch, the unidirectional gap between ball and the ball seat is about 0.005mm.Too smallly then go out Mo Buchang; Excessive then ink leak, even cause ball to come off.
The ball pen head material adopts brass (Cu+Zn) the earliest, because it is anticorrosive and wear resisting property is poor, replaced by Alpaka (Cu+Ni+Zn) gradually, but the erosion resistance of Alpaka and wear resisting property are still than stainless steel difference, what external high-grade ballpoint pen was used at present all is the stainless steel nib, domestic can't production, the used stainless material of the high-grade ball pen head of domestic production all is from Japanese import.
Summary of the invention
The purpose of this invention is to provide a kind of free-machining chromium stainless steel for ball pen head, this stainless steel has corrosion resistant, anti-corrosion wear performance and good free cutting property, is suitable for turning and makes ball pen head.
Technical scheme of the present invention is as follows:
Free-machining chromium stainless steel for ball pen head is characterized in that: matrix is Fe, and the percentage composition of all the other components is: C :≤0.03, and Si≤1.00, Mn≤2.00,0.15≤S≤0.5, P≤0.05, Cr19-21, Mo1.5-2.5, Pb0.10-0.30, Te0.01-0.07; O 〉=50ppm wherein in addition.
The ball pen head that the present invention produces free-machining chromium stainless steel has the following advantages:
1., corrosion resistant, wear-resisting, anti-corrosion wear.
2., be the pattern that collapses chip when good cutting performance and machining, be suitable for being processed into ball pen head.
Embodiment
One, free-machining chromium stainless steel for ball pen head is characterized in that: matrix is Fe, and the percentage composition of all the other components is: C :≤0.03, and Si≤1.00, Mn≤2.00,0.15≤S≤0.5, P≤0.05, Cr19-21, Mo1.5-2.5, Pb0.10-030, Te0.01-0.07; O 〉=50ppm wherein in addition.
Two, Production Flow Chart and parameter
10 tons of electric arc furnace (composition is proportioning on request) → 10 ton AOD stove (removes C, S, P measures oxygen content, composition goes out molten steel on request) → go out molten steel (in ladle, adding S) → ingot casting → cogging (be of a size of 65 sides, long for 1.3m) → finishing → esr and (add Pb, Te) → forge hot becomes 50 sides → finishing crop end, check → be rolled into that Ф 6.2mm dish circle → annealing → railway carriage becomes Ф 6.0mm (align---cold rolling sizing---railway carriage---rolling) → be cold drawn to Ф 5.7mm → clean annealing → be cold drawn to Ф 4.0mm → clean annealing → be cold drawn to Ф 2.8mm → clean annealing → be cold drawn to Ф 2.3mm → inspection after construction.
