A kind of van container hull boxboard steel and preparation method |
| abstract |
A kind of van container hull boxboard steel, component and wt% are：C：0.06~0.14%、Si：0.20~0.25%、Mn：2.51~2.79%、P≤0.015%、S≤0.005%、Mo：0.09~0.18%、Ce：0.095~0.22%.Preparation method：Base is casting continuously to form after smelting；Roughing；Finish rolling is simultaneously rolled to product thickness；It is cooling；Hole is cooled to room temperature.Chemical composition and production technology of the present invention are relatively easy, and procedure parameter is easy to control；In optics metallographic pattern lower strip thickness≤2 μm；Yield strength >=475MPa, fracture toughness Indexes Cracks tip opening displacement CTOD >=3mm；Non-plastic drop hammer test NDT≤65 DEG C, institute will not produce fracture problem in construction van container hull boxboard, can be in extremely cold Arctic safe navigation, and service life was up to 45 years. |
