Title:
STEEL FOR HIGH-CLEANLINESS CAMSHAFT AND ROLLING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/205794
Kind Code:
A1
Abstract:
Disclosed are steel for a high-cleanliness camshaft and a rolling method therefor. The mass percentages of the chemical components of the steel are as follows: C: 0.17-0.22%; Si: 0.17-0.37%; Mn: 1.10-1.40%; Cr: 1.00-1.30%; P: ≤0.020%; S: ≤0.020%; B: ≤0.0005%; Ti: ≤0.010%; Ca≤0.002%; Al: 0.020-0.060%; [O]≤12 ppm and [N]≤90 ppm, and the remainder being Fe and unavoidable impurities. In the present invention, by reasonably designing the rolling process, the hardness of the steel is stably controlled at 160-217 HB.
