Description
Technical field
The invention belongs to alloy fields, especially provide a kind of sulphur phosphor-copper combined lead-free ball pen head environment protection type easy
Cutting ferritic stainless steel material.
Background technique
The processing quality of ball pen head, except the precision of process tool and machining equipment and it is steady in addition to, key is easily
The quality of the comprehensive performance to cut stainless steel.There is following requirement to free cutting stainless steel:
Cutting free: nib processing uses Φ 1mm carbide drill, and with 30000 revs/min of High-speed machinings, charging rate is extremely
It is greater than 1.5mm/s less, therefore it is required that having good free cutting property.
Performance is uniform and stable:, be on Φ 2.3mm wire rod section since machining tool installation is all fixed and invariable
Hardness uniformity, otherwise will lead to processing dimension and lose shape, and performance wants stable and consistent in finite length, to guarantee
Last ball and written seat compress process not will cause gap too tight or too loose, prevent from causing not out of ink or ink leak or even ball
Pearl falls off.
Zero defect inside material: material internal flawless, shrinkage cavity, it is loose the defects of, otherwise will cause written process
The defects of size is inaccurate or cleaves.
It does not corrode: the corrosion of water-based ink, oily ink and organic alcohol solvent can be resisted.
Anti-corrosion wear: the gap of written ball seat and pearl increases, and just will affect writing quality and the service life of ball.
It is able to satisfy the free cutting stainless steel of above-mentioned requirements, it is recognized that for leaded preferable of FS20T, but lead has pollution to environment,
Therefore present invention employs sulphur, phosphorus, copper is pollution-free as combined Cutting free element avoids while reducing material cost
Environmental pollution.
Summary of the invention
The purpose of the present invention is to provide a kind of lead-free ball pen head environment protection type easy cutting ferritic stainless steel materials

There is antibacterial action under state.
The weight ratio of tri- kinds of elements of Cu, S, P is Cu:S:P=15-20:1- in the alloy as a preferred technical solution,
2.5:2.0-3.5 or Cu:S:P=15-20:2-3:1.5-2.5.
The chemical component of lead-free ball pen head environment protection type easy cutting ferritic stainless steel material of the present invention is into one
Step is preferred are as follows: C < 0.02, Si≤0.5, Mn 1-2, Cr 19-21, Cu 1.7-1.9, S0.15-0.25, P 0.2-0.3, Al
0.05-0.2, Fe surplus.
The preparation method of stainless steel material of the present invention, it is characterised in that: the stainless steel material using vacuum induction/
Normal pressure induction+electroslag remelting process or VOD+ continuous casting strip plate technique are smelted.
The present invention also provides the methods using stainless steel material of the present invention preparation silk material, it is characterised in that: stainless
It is heated to finish forge at 1100 DEG C -1150 DEG C after steel smelting and causes Φ 50-80mm, is then rolled into Φ at 1100 DEG C -1150 DEG C
