Abstract

The invention discloses a kind of drill bit steel alloy, the chemical element component and its mass percent that contain are：Carbon 0.087-0.095%, silicon 0.02-0.03%, copper 0.025-0.03%, chromium 0.03-0.04%, nickel 0.02-0.04%, vanadium 0.001-0.002%, tungsten 0.035-0.04%, vanadium 0.05-0.06%, zirconium 0.013-0.018%, niobium 0.024-0.025%, sulphur 0.45-0.5%, phosphorus 0.08-0.1%, surplus are iron.The advantage of the invention is that：Drill bit is made using preferred steel alloy formula in the present invention, and production cost is low, and tensile strength, yield strength, hardness are higher, the alloying elements such as a variety of nickel, vanadium, tungsten are added in constituent, it uniformly is distributed in steel alloy internal structure, brittleness is reduced, increases the service life of drill bit.

Description

A kind of drill bit steel alloy
Technical field
The present invention relates to drill bit material technical field, more particularly to a kind of drill bit steel alloy.
Background technology
Electric drill is a kind of widely used electric tool, building, processing and other fields be widely used, electric drill it is main Principle is the rotation by motor, driving apparatus for work is driven, to make drill bit scraping material surface to pierce object, drill bit It is one of essential component of electric drill；And electric drill is in use, to bear the Radial resistant force of motivation and drilled object, bores It is most common damage mode that head, which fractures, this is because the drill bit tool steel now used is in the feelings for ensureing to have some strength Under condition, brittleness improves and toughness is insufficient, and therefore, drill bit, which is susceptible to, to fracture, and the abrasion condition of drill bit is also to influence drill bit One of the reason of efficiency.
Invention content
The technical problem to be solved in the present invention is to provide a kind of drill bit conjunctions that can prolong the service life and reduce cost Jin Gang.
In order to solve the above technical problems, the technical scheme is that：A kind of drill bit steel alloy, innovative point are： Its chemical element component contained and its mass percent are：Carbon 0.087-0.095%, silicon 0.02-0.03%, copper 0.025- 0.03%, chromium 0.03-0.04%, nickel 0.02-0.04%, vanadium 0.001-0.002%, tungsten 0.035-0.04%, vanadium 0.05- 0.06%, zirconium 0.013-0.018%, niobium 0.024-0.025%, sulphur 0.45-0.5%, phosphorus 0.08-0.1%, surplus are iron.
Further, carbon 0.09%, silicon 0.025%, copper 0.028%, chromium 0.035%, nickel 0.03%, vanadium 0.001%, tungsten 0.04%, vanadium 0.055%, zirconium 0.016%, niobium 0.024%, sulphur 0.5%, phosphorus 0.09%, surplus are iron.
The advantage of the invention is that：Drill bit is made using preferred steel alloy formula in the present invention, and production cost is low, tension Intensity, yield strength, hardness are higher, and the alloying elements such as a variety of nickel, vanadium, tungsten are added in constituent, uniform to be distributed In steel alloy internal structure, brittleness is reduced, increases the service life of drill bit.
