| 精密铸件不锈钢材质有以下几种: 型号301-延展性好，用于成型产品。也可通过机械加工使其迅速硬化。焊接性好。抗磨性和疲劳强度优于304不锈钢。型号302-耐腐蚀性同304，由于含碳相对要高因而强度更好。型号303-通过添加少量的硫、磷使其较304更易切削加工。 There are several kinds of stainless steel materials for precision castings: model 301 - good ductility, used for molding products. It can also be hardened rapidly by machining. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel. Model 302 - the corrosion resistance is the same as that of 304. Because the carbon content is relatively high, the strength is better. Model 303 - it is easier to cut than 304 by adding a small amount of sulfur and phosphorus. 型号304-通用型号；即18/8不锈钢。GB牌号为0Cr18Ni9。型号309-较之304有更好的耐温性。型号316-继304之后，第二个得到*广泛应用的钢种，主要用于食品工业和外科手术器材，添加钼元素使其获得一种抗腐蚀的特殊结构。 Model 304 - general model; 18 / 8 stainless steel. The GB brand is 0Cr18Ni9. Model 309 has better temperature resistance than 304. Model 316 - the second widely used steel after 304, which is mainly used in food industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. |
