3Cr2MnNiMo--预加硬塑胶模具钢详细描述：出厂状态：经硬化及回火至DELIVEREDCONDITION290330HB硬度钢材特性：（1）此钢经已热处理，硬度均匀透稳（HB290-330）制成工模***。（2）除较细花式外，多已刨除表面氧化黑皮，故材料利用率高，且可减少加工费用。（3）经超音波检验，硬度及金相结构均匀，且容易达成镜面磨光。（4）可用火焰方法于空气中硬化，使部份易损地方加硬至50-55HRC约5mm深度。（5）因硫量低，对火花电蚀更为适合。尺寸规格：圆形（MM）2228354351556370768090102115127153180203232254300扁形（MM）20X105-130-166-206-254-300-350-400-450-500-600-102028X105-130-166-206-254-300-350-400-450-500-600-102035X105-130-166-206-254-300-350-400-450-500-600-102043X105-130-166-206-254-300-350-400-450-500-600-102054X105-130-166-206-254-300-350-400-450-500-600-102063X105-130-166-206-254-300-350-400-450-500-600-102080X105-130-166-206-254-300-350-400-450-500-600-1020100X105-130-166-206-254-300-350-400-450-500-600-1020125X105-130-166-206-254-300-350-400-450-500-600-1020160X105-130-166-206-254-300-350-400-450-500-600-1020200X105-130-166-206-254-300-350-400-450-500-600-1020250X105-130-166-206-254-300-350-400-450-500-600-1020300X105-130-166-206-254-300-350-400-450-500-600-1020350X105-130-166-206-254-300-350-400-450-500-600-1020牌号化学成份CSiMnCrNiMoVPS3Cr2MnNiMo0.33-0.370.15-0.350.80-1.01.65-1.750.4-0.50.4-0.5---上海荣昆金属制品有限公司欢迎广大客户来电咨询订购。电话：021-57886296传真：021-57886095***:894551548)
