| titleOfInvention | A kind of preparation method of nanosizing low-alloy heat-resistant high-strength steel mould |
| abstract | The invention discloses a kind of preparation method of nanosizing low-alloy heat-resistant high-strength steel mould, comprise the following steps：(1) mould raw material is carried out to smelting cast, rolling successively, low-alloy steel is obtained；(2) low-alloy steel is processed, obtains low-alloy steel mould；(3) low-alloy steel mould is carried out to nanosizing processing, nitrogen treatment, oxidation processes, immersion oil processing successively, making Nano surface low-alloy steel mould is obtained；Mould raw material in the step (1), is made up of the raw material of following mass percents：C 0.09 0.15%, Cr 1.35 1.55%, Si 0.22 0.28%, Mn 0.33 0.38%, Mo 0.17 0.24%, Ni 0.05 0.15%, Nb 0.05 0.08%, V 0.15 0.35%, P 0.002 0.008%, S 0.002 0.008%, surplus is Fe.Present invention process is simple, and with low cost, energy-conserving and environment-protective are nuisanceless, working environment cleaning, the features such as appearance looks elegant；Every environmental protection index is determined through environmental administration and is up to state standards, while making the wearability of metal surface, corrosion resistance and mechanical property hardness strength have raising by a larger margin. |
