Abstract

The invention discloses a cold-rolled steel strip for saw-chain cutter teeth, wherein the cold-rolled steel strip comprises the following chemical composition by mass: 0.61%=<C=<0.72%; 0.15%=<Si=<0.30%; 0.30%=<Mn=<0.40%; 0.10%=<Cr=<0.20%; 0.90%=<Ni=<1.10%; 0%=<Mo=<0.02%; 0.03%=<Ni=<0.05%; 0%<P=<0.02%; 0%<S=<0.01%; and the balance Fe. A target product can be obtained from hot-rolled raw materials through hot rolling, cold rolling, annealing and cutting. The test result of the final product meets the target value of the customer demand and is 95% or more. The cold-rolled steel strip for a saw chain has broad development prospects and great promotion and application value.

Description

(1) Technical field [0001] The invention relates to a cold-rolled steel strip for saw chain cutter teeth and a preparation method thereof. (2) Background technology [0002] Chain saws are mainly used for logging and lumbering. Its working principle is to perform shearing action by lateral movement of interlaced L-shaped blades on the saw chain. The saw chain is an important part of the chain saw, mainly composed of knife teeth, chain buckles, middle guide teeth, and rivets. Among them, the middle guide tooth is the main connecting part of the chain saw, and there is an oil injection hole on it to complete the conduction of lubricating oil and the lubrication of the entire chain; the main function of the rivet is positioning and fixing; the chain buckle is fixed in the middle by two rivets. On the guide tooth; the knife tooth is fixed on the middle guide tooth by two rivets, including the blade and the guard tooth. The overall quality requirements of the saw chain include ...
