Gray metal with high tensile strength. It is ductile, malleable, and resistant to atmospheric elements and all acids except strong alkalies.
钨是一种耐压强度较高的灰色金属，延展性很好，可以抵抗大气和所有除强碱外酸性物质的腐蚀。
Report on the First Phase of the Experiment in the Rapid Graphitizing of Malleable Cast Iron By " Hot Soaking-Plating in the Liquid of Metal "
可锻铸铁热浸镀快速石墨化试验第一阶段报告
Applicable to high tensile strength metal grinding, such as general carbon steel, alloy steel, malleable iron hard bronze.
适用于中高抗张强度金属材料的磨削，如一般碳素钢，合金钢，可锻铸铁，硬青铜等。
The annealing process of multiple inoculations metal-mould malleable cast iron is compared with common inoculation one, the first stage graphitization annealing time is decreased from 45 minutes to 25 minutes, and the second stage graphitization annealing time is shortened from 350 minutes to 80 minutes.
复合孕育金属型可锻铸铁的退火工艺与普通孕育金属型可锻铸铁的相比，第一阶段石墨化退火时间由45min减少至25min；第二阶段石墨化退火时间由5h50min缩短至1h20min。
