Abstract

The invention discloses bismuth-containing free-cutting steel. The bismuth-containing free-cutting steel comprises the following components in percentage by weight: 0.04%-0.15% of C, 0-0.15% of Si, 0.9%-1.6% of Mn, 0.02%-0.11%of P, 0.25%-0.45% of S, 0-0.2% of Cr, 0-0.2% of Ni, 0-0.2% of Cu, 0.05%-0.2% of Bi, 0.005%-0.05% of Ti, 0.005%-0.05% of N, 0-0.2% of impurities and the balance of Fe. According to the bismuth-containing free-cutting steel disclosed by the invention, lead is substituted by the bismuth, so that a lead pollution problem is solved; meanwhile, the thermal plasticity and the after-breakage elongation are better, so that the bismuth-containing free-cutting steel is unlikely to fracture during a rolling process. The bismuth-containing free-cutting steel disclosed by the invention has excellent comprehensive mechanical performances, cutting performances superior to those of the common free-cutting steel, and cutting performances equivalent to those of the lead-containing free-cutting steel. Meanwhile, the bismuth-containing free-cutting steel is free of lead, good in environment friendliness, and beneficial to popularization and utilization.

Description

technical field [0001] The invention relates to a stretch-resistant antibacterial fabric containing polyketone fibers and a preparation process thereof. Background technique [0002] In recent years, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics, and there are more and more demands for safe, efficient and high tensile strength clothing; however, the current high tensile strength materials added The ingredients are relatively single, and the functions it has are also relatively single. There is no unified solution to the functions of comfort, stretch resistance, insecticide, sweat absorption, and warmth. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a stretch-resistant and anti-bacterial fabric containing polyketone fiber, which has the functions of comfort, stretch resistance, insecticidal, sweat-absorbing, and warm-keeping; The pro...
