Applications：

When quenching and heating (up to 800℃), the fine grain structure of T10 steel can still be maintained.Have not dissolve excess of carbide in steel after quenching and so is of T8 steel with high abrasion resistance, suitable [TJC STEEL]for cutting edge at work the same hot tools, such as processing wood cutter, hand cross cut saw, sawing machine, hand joinery with fine woodworking saws, twist drill, wire drawing die, die, cold heading die, small size of uniform cold trimming and piercing die and low precision in the shape of a simple card board, fitter scraper, file, etc.
