Hot-worked Tool steel having superior hot workability and high strength for slab sizing press anvil

摘要

The present invention relates to relates to a tool steel is used as a sizing press anvil used to reduce to a certain range of the width of the hot rolled slab of steel mills, in particular the part is hot-formability superior and strong wear resistance to be suitable for hot forming high-strength hot tool steel . ; The present invention in weight%, C: 0.36 ~ 0.6%, Si: 0.3 ~ 1.5%, Mn: 0.2-2.0%, Cr: 7.0 ~ 10.0%, Ni: 0.5-1.5%, Co: 0.8% or less, Mo: 0.6-1.8%, W: 0.3-2.0%, V: 0.4-1.5%, Nb: 0.8% or less, Ta: 0.8% or less and remainder Fe and other excellent hot rolling the hot slab formability characterized in that a composition as inevitable impurities It provides a high strength tool steel for hot sizing press anvil.
