Abstract
The invention discloses a kind of high intensity hardware tool steel, handware further includes copper, magnesium, nitrogen, carbon, tungsten, nickel, potassium and calcium using iron as main component, and gas content is nitrogen≤300ppm in handware.The beneficial effects of the invention are as follows：By the synergistic effect between raw material, while proof strength, the ductility and toughness of material is improved, service life is extended, meets the needs of different industries.
Description
Technical field
The present invention relates to a kind of handware more particularly to a kind of high intensity hardware tool steel.
Background technology
Hardware tool is important basic part, builds in most of Mechanical Product's Machinings, engineering structure, the dimensions of all products
Repair and daily life in using very extensive.Hardware tool is highly professional steel grade with steel, it should have high harden
Surface and the tough and tensile center portion of soft, while also there is high-speed cutting, processing performance, there is certain processing red hardness, especially
It is to shear cannot jump mouth, chip off-falling, peeling etc..Since steel grade should have these special performances, conventional hardware tool is with steel master
If adding a large amount of alloying element chromium Cr, nickel, molybdenum Mo, vanadium V etc. in medium carbon steel, or even also increase tungsten W, titanium Ti and cobalt Co etc.
Valuable rare heavy metal forms consolidating for disperse by controlling alloy smelting, the cooling of rolling (forging) temperature control, processing and heat treatment
Carbon compound hardening constituent is precipitated in molten tissue, you can obtains mechanical property, the processing performance etc. required by the above hardware tool.It is many
Well known, alloying element chromium Cr, nickel, molybdenum Mo, vanadium V etc. or tungsten W, titanium Ti and cobalt Co etc. are expensive, using these alloys member
The steel grade cost of element production is high, and the hardware tool certainty price height of manufacture, the market sales volume are few.Meanwhile using these costlinesses
The tool of steel manufacture, service life is greatly rich, and resource is wasted.In addition, with the development of metallurgical technology, steel material
Degree of purity improves, and the technological levels such as processing and heat treatment are specialized, and the alloy added in hardware tool steel gradually reduces.
Therefore, to solve the above problems, providing a kind of new technical solution.
Invention content
The present invention provides a kind of high intensity hardware tool steel.
The technical solution adopted by the present invention is：
A kind of high intensity hardware tool steel, the handware using iron as main component, further include copper, magnesium, nitrogen, tungsten, nickel, potassium and
Calcium, gas content is nitrogen≤300ppm in the handware.
Further, component is respectively by mass percentage：The copper of 10-20%, the magnesium of 2-5%, the nitrogen of 0.5-1%, 2-4%
Tungsten, the nickel of 0.4-0.9%, the potassium of 0.2-1%, 1-2% calcium, surplus be iron and inevitable impurity.
Further, further include rare earth element.
Further, the rare earth element is antimony and erbium.
Further, the mass percent of the antimony is 0.01-0.03%, and the mass percent of the erbium is 0.02-
0.05%。
The beneficial effects of the invention are as follows：By the synergistic effect between raw material material is improved while proof strength
Ductility and toughness, extend service life, meet the needs of different industries.
Specific implementation mode
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment

0.5% nitrogen, 2% tungsten, 0.4% nickel, 0.2% potassium, 1% calcium, 0.01% antimony, 0.02% erbium, surplus is that iron and can not keep away
The impurity exempted from.
Embodiment 2
A kind of high intensity hardware tool steel, handware further include copper, magnesium, nitrogen, tungsten, nickel, potassium, calcium, antimony using iron as main component
And erbium, gas content is nitrogen≤300ppm in handware, and component is respectively by mass percentage：15% copper, 3% magnesium,
0.75% nitrogen, 3% tungsten, 0.7% nickel, 0.6% potassium, 1.5% calcium, 0.02% antimony, 0.035% erbium, surplus is iron and not
Evitable impurity.
Embodiment 3
A kind of high intensity hardware tool steel, handware further include copper, magnesium, nitrogen, tungsten, nickel, potassium, calcium, antimony using iron as main component
And erbium, gas content is nitrogen≤300ppm in handware, and component is respectively by mass percentage：20% copper, 5% magnesium, 1%
Nitrogen, 4% tungsten, 0.9% nickel, 1% potassium, 2% calcium, 0.03% antimony, 0.05% erbium, surplus be iron and inevitably it is miscellaneous
Matter.
The beneficial effects of the invention are as follows：By the synergistic effect between raw material material is improved while proof strength
Ductility and toughness, extend service life, meet the needs of different industries.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and according to the technical essence of the invention made by any modification or equivalent variations, still fall within present invention model claimed
