你好！我想问下具体哪种钢强度、韧性、抗拉强度好？越详细越好！谢谢
推荐回答（3个）
YW1——红硬性较好，能承受一定的的冲击负荷，是通用性较好的 合金.适于耐热钢高锰钢不锈钢等难加工钢材的加工，也 适于普通钢和铸铁的加工.
YW2——耐磨性仅次于YW1，单其使用强度较高，能承受较大的冲 击负荷，适于耐热钢高锰钢不锈钢及高级合金钢的粗加工 半精加工，也适于普通钢和铸钢.
YT30——耐磨性和运行的切削速度较YT15高，但使用强度抗冲击韧 性较差。适于碳素钢与合金钢的精加工，如小断面的精车 精镗，精扩等.
YT15——耐磨性优于YT15合金，但抗冲击韧性较YT5差。适于钢， 铸钢，合金钢中切削断面的半精加工或小切削断面精加工.
YT14——使用强度高，抗冲击和抗震性好，近次于YT5合金，但耐 磨性较YT5好，适于碳素钢与合金钢连续切削时的粗车粗 铣，间断切削时的半精车和精车。
YT5——在钨钴钛合金中强度，抗冲击及抗震性最好，但耐磨性较 差。适于碳素钢与合金钢（包括锻件，冲压件，铸铁表皮 ）间断切削时的粗车粗刨半精刨。
YG3X——在钨钴钛合金中耐磨性最好，但冲击韧性较差，适于铸铁 有色金属及其合金，碎火钢，合金钢小切面的高速精加工.
YG3——耐磨性仅次于YG3X，对冲击和震动较敏感，适于铸铁有色 金属及其合金连续切削时的精车半精车，精车螺纹与扩孔
YG6A——属细颗粒合金，耐磨性好，适于冷硬铸铁，有色金属及其 合金的半精加工，亦适于碎火钢合金钢的半精加工及精加 工。
YG6X——属细颗粒碳化钨合金，其耐磨性较YG6高，使用强度近似 于YG6合金，适于加工冷硬合金铸铁与耐热合金钢，也适 于普通铸铁的精加工.
YG6——耐磨性较高，但低于YG3，抗冲击和震动比YG3X为好。适 于铸铁，有色金属及合金，非金属材料中等切削速度的半 精加工和精加工。
YG8——使用强度高，抗冲击，抗震性较YG6好，但耐磨性和允许 的切削速度较低。适于铸铁，有色金属及合金，非金属材 料低速粗加工。
YD201——适用于铸铁、轻合金的半精加工、粗加工、亦可作为铸铁 、低合金钢的铣削加工.
含铝的钢韧性都好的，含硅的挠度、弹性都好，含锰、钒的强度可以的
