The 300 MPa grade enamel steel is with low-carbon composition design, such alloy elements as Mn, Nb and Ti are added, tapping temperature of heating furnace in hot rolling is controlled at 1 200~1 230 ℃, finishing temperature≥890 ℃, coiling temperature≤580 ℃, cold rolling reduction ratio≥65% as well as continuous annealing temperature is selected to be 830 ℃. The yield strength of developed high strength enamel steel is 367 MPa, which is still over 300 MPa after enameling as well as its microstructure mainly consists of uniform equiaxed ferrite with Fe3C and dispersed TiC precipitates. The TiC could effectively pin grain boundaries to prevent grain coarsening during high temperature treatment process. TH (sensitivity of resistance to scute burst) is 6.80~7.23 min/mm2, which could meet the requirements of EN 10209—2013 standard (TH>6.7 min/mm2).

300 MPa级搪瓷钢采用低碳成分设计,添加Mn、Nb、Ti等合金元素,热轧加热炉出炉温度控制在1 200~1 230 ℃,终轧温度≥890 ℃,卷取温度≤580 ℃,冷轧压下率≥65%,连续退火温度选择830 ℃。开发的高强搪瓷钢屈服强度为367 MPa,搪烧后屈服强度仍大于300 MPa,其微观组织主要由均匀的等轴铁素体构成,并伴随有Fe3C及弥散分布的TiC析出相,TiC可有效钉扎晶界,抑制高温处理过程中的晶粒粗化。产品抗鳞爆敏感性TH值为6.80~7.23 min/mm2,满足EN 10209—2013标准(TH>6.7 min/mm2)要求。

300 MPa级搪瓷钢采用低碳成分设计,添加Mn、Nb、Ti等合金元素,热轧加热炉出炉温度控制在1 200~1 230 ℃,终轧温度≥890 ℃,卷取温度≤580 ℃,冷轧压下率≥65%,连续退火温度选择830 ℃。开发的高强搪瓷钢屈服强度为367 MPa,搪烧后屈服强度仍大于300 MPa,其微观组织主要由均匀的等轴铁素体构成,并伴随有Fe3C及弥散分布的TiC析出相,TiC可有效钉扎晶界,抑制高温处理过程中的晶粒粗化。产品抗鳞爆敏感性TH值为6.80~7.23 min/mm2,满足EN 10209—2013标准(TH>6.7 min/mm2)要求。

300 MPa级搪瓷钢  /  力学性能  /  抗鳞爆性能

The 300 MPa grade enamel steel is with low-carbon composition design, such alloy elements as Mn, Nb and Ti are added, tapping temperature of heating furnace in hot rolling is controlled at 1 200~1 230 ℃, finishing temperature≥890 ℃, coiling temperature≤580 ℃, cold rolling reduction ratio≥65% as well as continuous annealing temperature is selected to be 830 ℃. The yield strength of developed high strength enamel steel is 367 MPa, which is still over 300 MPa after enameling as well as its microstructure mainly consists of uniform equiaxed ferrite with Fe3C and dispersed TiC precipitates. The TiC could effectively pin grain boundaries to prevent grain coarsening during high temperature treatment process. TH (sensitivity of resistance to scute burst) is 6.80~7.23 min/mm2, which could meet the requirements of EN 10209—2013 standard (TH>6.7 min/mm2).
