这是一种具有理想磁性适宜做变压器铁芯等电力材料的低合金钢。这种材料能改善织构降低铁损。这种合金含有0.6～1.0％硅、0.4～0.8％铬,同时要控制锰、硫、碳和氧的含量。这些合金最好经三次冷轧法加工成最终厚度为0.006英吋(0.015Cm)规格。这些合金的B_(10)在19千高斯以上,17千高斯下的铁损低于0.72瓦/磅。
This is a kind of low alloy steel with ideal magnetism suitable for making power material such as transformer iron core. This material improves texture and reduces iron loss. This alloy contains 0.6 to 1.0% silicon and 0.4 to 0.8% chromium, while controlling the contents of manganese, sulfur, carbon and oxygen. These alloys are best machined to a final thickness of 0.006 inch (0.015 cm) by three cold rolling processes. The B_ (10) of these alloys is above 19 kilo-gauss and the iron loss at 17 kilo-gauss is below 0.72 watts per pound.
