供应东北特钢M2，，价格合理！质量保证！
M2是钼系高速钢,具有碳化物不均匀性小和韧性较高的优点.易于过热,故应严格控制淬火加热温度,对热处理保护要求较严.由于其硬度和耐磨性好,多用于制造切削较难切削材料的刀具.M2高速钢具有碳化物倾向性较大,故对热处理保护要求较严,适合承受震动和冲击荷载的模具.
主要用途:
冷锻模、精冲模、粉末压制模等，剪切机模，添加玻纤之塑料模等。适合承受震动和冲击荷载的模具：深拉模具、冲孔模。金属切割锯刃，冷镦和挤出工具等。

The supply of Dongbei special steel M2, M2 steel, M2 steel, the price is reasonable! Quality assurance!
M2 is molybdenum high speed steel, carbides and higher toughness of the advantages with. Easy to overheating. Therefore, it should be strict control of quenching temperature, the thermal protection requirements more stringent. Due to its hardness and wear resistance, used for manufacturing cutting harder material cutting tool.M2 high-speed steel carbide tend to have larger, so on the thermal protection requirements more stringent, suitable to withstand vibration and shock load of the mold.
Main purpose:
Cold forging die, precision die, powder pressing die, die cutting machine, the addition of glass fiber plastic mould etc.. Suitable for bearing vibration and impact load of the mold: deep drawing die, punching die. The metal cutting saw blade, cold forging and extrusion tools etc..
