15MnV钢板归于低合金高强度结构钢，是在碳素结构钢的基础上，参加少数的合金元素发展起来的，原称一般低合金钢。
15MnV钢板功能特色：
强度高于碳素结构钢，然后可下降结构自重、节省钢材；
具有满足的塑性、耐性及杰出的焊接功能；
具有杰出的耐蚀性和低的冷脆改变温度。
15MnV钢板规范:GB/T699-1988
15MnV钢板适用范围:
强度及淬透性15MnV高,冷变形时的塑性中等可切削性好,但焊接性较差。宜调质处理后运用。适用于转轴.螺栓.螺母.螺钉等,心轴.齿轮用于制作中型机械中的螺栓、螺母、杠杆等。淬透性略高于40钢。热处理后,强度.硬度.耐性比40钢稍高,冷变形塑性中等,可切削性好,焊接性低,具有过热敏感性和回火脆性,水淬易裂。适用于耐疲惫
15MnV与20MnV的差异：
两种资料都归于优质碳素结构钢,首要差异是含碳量不同,其他成分都是样的。含碳量的不同跟资料功能有直接关系。15Mnⅴ冷变形时的塑性中等可切削性好,但焊接性较差。宜调质处理后运用。适用于转轴.螺栓螺母.螺钉轴齿也用于制作中型机械中的螺栓、螺母、杠杆等。20Mnⅴ碳素结构钢可在正火状:下运用,也可在淬火和回火状态下运用。切削加工功能好,冷变形时的塑性中等焊接功能不良。用于制作接受疲惫负荷的零件,如轴辊及高应力下作业的螺钉、螺帽理后,焊接性低,具有过热敏感性和回火脆性易裂。适用于耐疲惫件曲轴辊子轴.连杆。
15MnV steel plate belongs to low alloy high strength structural steel, is on the basis of carbon structural steel, participate in a few alloying elements developed, formerly known as general low alloy steel.
15MnV steel Plate Features:
the strength is higher than carbon structural steel, then can reduce the structure weight, save steel;
It has satisfactory plasticity, endurance and excellent welding function;
Excellent corrosion resistance and low cold - brittle change in temperature.
15MnV steel Plate specification :GB/T699-1988
15MnV steel plate applicable scope:
High strength and hardenability 15MnV, plastic medium machinability good cold deformation, but poor weldability.It is advisable to use after tempering.For swivel shaft. Bolts.Nuts, screws, mandrel, etc.Gears are used for making bolts, nuts, levers and so on in medium machinery.It has a hardenability of slightly more than 40 steel.After heat treatment, strength.Hardness. Slightly higher tolerance than 40 steel, moderate cold deformation plasticity, good machinability, low weldability, overheating sensitivity and temper brittleness, water quenching easy crack.Suitable for fatigue resistance
Difference between 15MnV and 20MnV:
Both materials are attributed to high quality carbon structural steel, the primary difference is the different carbon content, other components are the same.The difference of carbon content is directly related to data function.When capable of forming a cold deformation of 15Mn, the capable of intermediate machinability is good, but the capable of welding is poor.It is advisable to use after tempering.For shafts, bolts and nuts.Screw shaft teeth are also used for making bolts, nuts, levers and so on in medium machinery.A 20Mn carbon structural steel can be applied under the condition of normalizing; it can also be applied under the condition of quenching and tempering.Good machining function, poor plastic welding function in cold deformation.Used for making parts that accept fatigue load, such as shaft roller and screws, nuts under high stress, low weldability, overheat sensitivity and temper brittleness easy crack.Suitable for fatigue resistant crankshaft roller shafts.The connecting rod.
