These are graphite, highsiliconcastiron, lead silver alloy, platinum, and even scrap steel rails.
所用材料有石墨、高硅铸铁、铅银合金、铂、甚至废钢轨等。
2
The influences of inoculation and overheating insulation on the property of the highsiliconcastiron were studied.
研究了孕育处理和过热保温对高硅铸铁性能的影响。
3
Thus transport of sulfuric acid pump usually highsiliconcastiron (casting and processing is very difficult), high-alloy stainless steel (alloy No. 20) to create.
