Definitions
- the present invention relates to an abrasion-resistant steel and its method of manufacture.
- quenching may be followed by tempering at a temperature below 350 ° C, and preferably below 250 ° C.
- the hardness is between 280 HB and 450 HB.
- VS * VS - Ti / 4 - Zr / 8 + 7 ⁇ NOT / 8 ⁇ 0 , 095 %
- the chemical composition is chosen so that the quenchability of the steel is sufficient, given the thickness of the sheet that is to be manufactured.
- the steel is made, cast in the form of a slab or ingot.
- the slab or slug is hot-rolled to obtain a sheet which is subjected to a heat treatment which makes it possible at the same time to obtain the desired structure and a good flatness without subsequent planing or with limited planing.
- the heat treatment can be carried out in the hot rolling or later, possibly after a cold or mid-heat planing.
- the sheets A to D have a martensite-bainitic self-regenerating structure containing about 10% retained austenite, as well as titanium carbides, while the plates E to G have a completely martensitic structure, the sheets G and H also containing large titanium carbides.
