Abstract
The invention relates to a corrosion resistant bolt. The corrosion resistant bolt is characterized by consisting of the following components in mass ratio of C to Si to Mn to P to S to Alt to Cr to V to N to W to Ti to Zn to Pb to Nb to Re being (15-35) to (18-25) to (8-25) to (5-17) to (10-20) to (20-60) to (10-15) to (2-5) to (2-5) to (5-16) to (1-4) to (10-16) to (25-35) to (12-18) to (5-13). According to the technical scheme adopted by the invention, by virtue of a reasonable proportion, the produced bolt is high in strength and can meet the requirements in special industries such as space flight, petroleum exploration and the like; the strength level of the bolt reaches 12.9, the production cost of the bolt is relatively low, and the large-scale popularization and application is convenient; and the bolt has good corrosion resistance, and can be used for a long time in relatively bad environments such as oceans, lakes and the like.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of corrosion-resistant bolt, belong to bolt production technical field.
Background technique
Bolt as the one of mechanical parts, 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 technological scheme of exigence solves this technical problem.
Summary of the invention
