Steel bars and resulfurizado refosforizado, free Processing Machine, Cold Drawn, with controlled mechanical properties and capacity controlled Processing Machine

摘要

The present Invention relates to a Steel Bar Processing machine and free, resulfurizado refosforizado, Cold Drawn, that is the composition by weight: c to 0.08 percent MN 0.6 percent to 1.4 percent to 0.1 percent if P at least 0.03 percent s of 0.25% to 0.50 percent CB 0.01 percent to 10 percent v to 0.1 percent of the amount of ni, CR, Mo and cu to 0.15 percent, the rest of Iron. The percent ratio of MN / s is 1.6 percent to 4.0 percent and the relationship (Mn - 1.62 x percent S) / percent CB is from 2 to 50.
