Abstract
The invention relates to a high-strength bolt. The high-strength bolt is characterized by comprising, by mass, 15-35 parts of C, 20-25 parts of Si, 10-25 parts of Mn, 5-15 parts of P, 10-20 parts of S, 20-60 parts of Alt, 10-15 parts of Cr, 2-5 parts of V, 2-5 parts of N, 5-15 parts of W and 1-3 parts of Ti.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of high strength bolt, belong to bolt production technical field.
Background technology
Bolt as the one of mechanical component, adapted
nutcylindrical threaded
fasteningpart, by head and
screw roda class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.Bolt is applied in all trades and professions widely, but in the requirement of different industries to bolt strength, such as in the field such as space flight, petroleum detection, higher to the requirement of bolt strength, but bolt in the market meets the requirement of all trades and professions very slowly completely, therefore, a kind of new technical scheme of exigence solves this technical problem.
Summary of the invention
The present invention, just for the technical problem existed in prior art, provides a kind of high strength bolt, and this bolt strength is high, meets the requirement of special industry.
In order to solve above-mentioned Problems existing, technical scheme disclosed by the invention is as follows, a kind of high strength bolt, it is characterized in that, composition and the mass ratio of described high strength bolt are as follows: C:Si:Mn:P:S:Alt:Cr:V:N:W:Ti is 15-35:20-25:10-25:5-15:10-20:20-60:10-15:2-5:2-5:5-15:1-3.
As a modification of the present invention, composition and the mass ratio of described high strength bolt are as follows: C:Si:Mn:P:S:Alt:Cr:V:N:W:Ti is 18-30:21-24:15-23:6-13:12-18:25-50:11-14:3-4:3-5:6-12:1. 5-2.5.
A kind of high strength bolt, it is characterized in that, composition and the mass ratio of described high strength bolt are as follows: C:Si:Mn:P:S:Alt:Cr:V:N:W:Ti is 20:22:20:10:16:30:12:3:4:10:2.
A kind of high strength bolt, it is characterized in that, composition and the mass ratio of described high strength bolt are as follows: C:Si:Mn:P:S:Alt:Cr:V:N:W:Ti is 19:21:16:8:13:28:11:3:3:6:1.5.
A kind of high strength bolt, it is characterized in that, composition and the mass ratio of described high strength bolt are as follows: C:Si:Mn:P:S:Alt:Cr:V:N:W:Ti is 28:24:23:13:18:50:14:4:5:12:2.5.
Relative to prior art, advantage of the present invention is as follows, and 1) this technical scheme is by rational proportioning, and the bolt strength of production is high, can meet the requirement of the special industry such as space flight, petroleum detection; 2) intensity of this bolt reaches 12.9 grades, and the production cost of this bolt is lower, is convenient to apply on a large scale.
