The O1 tool steel is a cold work steel with high levels of carbon in its composition It is part of the O group of steels which means it is oil hardening This group of steels contains O2 O6 O7 and O1 tool steels O1 is a general purpose steel suitable for various applications It has high machinability and requires lower hardening The hardenability of a metal alloy is the depth to which a material is hardened after putting it through a heat treatment process It should not be confused with hardness which is a measure of a sample s resistance to indentation or scratching It is an important property for welding since it is inversely proportional to weldability that is the ease of welding a material Tight Tolerance Multipurpose Oil Hardening O1 Tool Steel Rods Yield Strength 50 000 psi Hardness Rockwell B90 Medium Heat Treatable Yes Max Hardness After Heat Treatment Inch sizes Rockwell C65 Metric sizes Rockwell C62 Specifications Met ASTM A681 McMaster Carr is the complete source for your plant with over 700 000 products 98 of products ordered ship from stock and deliver same or next day Tempering temperature 150 230 176 C for 2 4 hours Rockwell hardness 58 64 HRC As quenched Rockwell hardness after heat treatment is typically 64 67 HRC Applications 52100 bearing steel mainly used for bearings bearing races seal rings balls rollers guide bars sleeves knives and blades etc Equivalent Grades

O1 tool steel is an oil hardening cold work general purpose steel with easy machining properties and low hardening temperatures compared to other grades O1 provides good wear resistance and toughness sufficient for standard tool and die applications making it a suitable choice for tooling with good tool life and econimcal production In Finland German silver steel was and still is widely used for Puukko knives The composition is defined by the British Standard BS 1407 and is given below In the annealed state it has a hardness of 27 HRC It can be hardened to 64 HRC The European Werkstoff equivalent is 1 2210 115CrV3 which also includes some vanadium All testers come with a steel test block If you are checking aluminum you need an aluminum test block We have them Just call and tell us what scale you need HRBW Vickers HRE etc 1 978 897 1795 x Hardness as applied to most materials and in particular metals is a valuable revealing and commonly employed mechanical test that has been in use in various forms for Absolute hardness Image 1 Talc Mg 3 Si 4 O 10 OH 2 1 2 Gypsum CaSO 4 183 2H 2 O 2 3 Calcite CaCO 3 14 4 Fluorite CaF 2 21 5 Apatite Ca 5 PO 4 3 OH − Cl − F − 48 6 Orthoclase feldspar KAlSi 3 O 8 72 7 Quartz SiO 2 100 8 Topaz Al 2 SiO 4 OH − F − 2 200 9 Corundum Al 2 O 3 400 10 Diamond C 1500 On the Mohs scale a streak plate unglazed O1 OIL HARDENING TOOL STEEL ANNEALING Heat slowly and uniformly to 1140 176 F soak thoroughly and then allow to cool slowly in the furnace to below 1000 186 F STRESS RELIEVING When heavy machining cuts are employed the resultant stresses may be relieved by heating the material to 1200 1250 176 F for one hour and cooling in still air
