1.常用弹簧材料有:碳素弹簧钢,合金弹簧钢。碳素弹簧钢价格便宜,应用最广。但因“淬透性”差,弹簧较粗(或较厚)时,心部材料便达不到热处理需要的性能,只能制作钢丝直径较小(2～8毫米)的弹簧。有65、70、75、85等优质碳素钢。合金弹簧钢淬透性好,能制作大弹,且能适应变载及冲击。常用的有65Mn、55Si2Mn、60Si2Mn、50CrVA等。此外,在需防蚀时,可采用不锈钢。在需防磁、导电时,可分别采用某些有色金属,如硅锰青铜、锡锌青铜、铍青铜等。 2.通常弹簧钢丝直径在8毫来以上的用热卷法;钢丝直径在8毫来以下的可用冷卷法。
1. Commonly used spring materials: carbon spring steel, alloy spring steel. Carbon steel spring cheap, the most widely used. However, due to poor “hardenability” and spring thick (or thicker), the core material will not reach the performance required for heat treatment, and only the spring with the smaller wire diameter (2-8 mm) can be made. There are 65,70,75,85 other high-quality carbon steel. Alloy spring steel hardenability, can make a large bomb, and can adapt to the variable load and impact. Commonly used 65Mn, 55Si2Mn, 60Si2Mn, 50CrVA and so on. In addition, when corrosion is required, stainless steel can be used. In the anti-magnetic, conductive, can be used in certain non-ferrous metals, such as Si-Mn bronze, tin-zinc bronze, bronze and so on. 2 usually spring wire diameter of 8 millimeters or more with the hot coil method; wire diameter of 8 milliliters or less available cold roll method.
