O1 Flat Ground - Tool Steel

Tool Steel Flat - O1

O1 Flat Ground, is an oil-hardening, non-deforming tool steel which can be hardened at relatively low temperatures. Tools and dies made from O1 Flat Ground will have good wearing and abrasive qualities since the tungsten and higher chromium content gives improved wear resistance. O1 Flat Ground is ground to a surface finish of up to 35Ra on six sides and is free from defects and decarburization. Sold in annealed state to be heat-treated.
