30ХН3М2ФА俄标高强合金耐压耐热结构钢,该钢多呈现棒料、带材、厚板、实心环等。可用于制造工作温度高达+350°C的蒸汽轮机盘的坯料。 是,在这边库存少有,但依据标准在(高高兴晟特)可协议生产。
调质后该可用于均是领域特殊部件。之前常用的27ХН3М2ФА退出历史舞台。
碳±0.010%,硅+ 0.030%。
在制造轮毂高度为450至650毫米的轮坯时,钢中磷和硫的含量应不超过0.018%;对于VAR和ELP金属,锰含量的偏差为+0.10%。
在ESR钢中,硫含量不应超过0.015%。
在制造轮毂高度超过 300 毫米的圆盘坯料时,必须测定金属中的氢含量。

30ХСНВФА (ВП30)可代替之前多用的 25ХСНВФА (25CrNiWVSiA)
如果你小批量的复杂合金钢,如果没人生产您的钢,您 《高高特钢 。
If you need a small batch of complex alloy steel, if no one produces the steel you need.
支持小小批量试单;
支持第三方机构检测。30 ХН 3 М 2 Φ А Russian standard high-strength alloy pressure resistant and heat-resistant structural steel, which is mostly presented in bar, strip, thick plate, solid ring, etc. Can be used to manufacture blanks for steam turbine discs with working temperatures up to+350 ° C. Yes, there is limited inventory here, but according to the standards, it can be produced through an agreement with (Gaoxin Shengte).
After quenching and tempering, it can be used for special components in various fields. The previously commonly used 27 ХН 3 М 2 Φ А has exited the historical stage.
