30CrMnTi舞阳钢铁品种钢板订购批量优惠,拼单下料有优惠政策|舞钢资讯

1、为合金结构钢板。供应种类:热轧无缝管、冷拔管、精密钢管、热扩管、冷旋压管、挤压管、有缝管合金钢主要用钛渗碳钢。有时也可作为调质钢使用,渗碳及淬火后具有耐磨性好,静强度高的特点,热处理工艺性好,渗碳后可直接降温淬火,且淬火变形很小,高温回火时有回火脆性。 舞阳钢铁品种钢板订购批量优惠,拼单下料有优惠政策|舞钢资讯

2、执行标准:GB/、交货状态:以热处理(正火、退火或高温回火)或不热处理状态交货,交货状态应在合同中注明;热处理规范及金相组织:热处理规范:淬火:第一次880℃,第二次850℃,油冷;回火200℃,水冷、空冷;金相组织:回火马氏体。4、化学成分:C含量0.24-0.32之间,Mn含量0.80-1.10之间,Si含量0.17-0.37之间,P含量不大于0.035,S含量不大于0.035,Cr含量1.00-1.30之间,Ni含量不大于0.030,Cu含量待定,Ti含量0.04-0.10之间。5、力学性能: 抗拉强度不小于1470;伸长率不小于9;延伸率不小于18.     6、应用范围:

主要用作渗碳钢,渗碳后可降温直接淬火,弯曲强度较高、耐磨性能好;可在淬火低温回火或调质后使用,切削加工性中等;用于制造心部强度特高的渗碳零件,如齿轮轴,齿轮,蜗杆等,也可制造调质零件,如汽车、拖拉机上较大截面的主动齿轮等。用于制造拖拉机行业中截面较大的重负荷渗碳件及受力较大的齿轮、齿轮轴、蜗杆等。
