自贡764厂近年来研制出一种新型刀具材料YT04,可用来加工高硬度(HRC55～70)材料,现场使用证明,这种合金综合性能优良,寿命比相应牌号合金有所提高,深受用户的欢迎。表中列出了几次配料研制的情况。如表所列,YT04合金的硬度很高,且具有适中的强度,合金的组织机构也很均匀,WC晶粒几乎都是小于0.5μm以下的。粘结相的厚度也小于0.5μm。由于晶粒极细,硬度很高,故该合金具有极高的耐磨性、红硬性和热强度。这种合金的加工范围如下:硅铁、钒钛铸铁、加硼铸铁、
In recent years, Zigong 764 plant has developed a new tool material YT04, which can be used to process high hardness (HRC55 ~ 70) materials. It has been proven on site that this alloy has excellent overall performance and improved life expectancy compared with the corresponding grade alloy. welcome. The table lists several ingredients developed. As shown in the table, YT04 alloy hardness is high, and has moderate strength, alloy organization is very uniform, WC grains are almost all less than 0.5μm. The thickness of the binder phase is also less than 0.5 μm. Due to the fine grain, high hardness, so the alloy has a very high wear resistance, red hardness and hot strength. This alloy processing range is as follows: ferrosilicon, vanadium titanium cast iron, cast iron boron,
