Tool Steel Supplier

Basic properties that cutting must posses are: Tool material must be at least 30 to 50% harder than the work piece material. Tool material must have high hot hardness temperature. High toughness High wear resistance High thermal conductivity Lower  coefficient of friction Easiness in fabrication and cheap Different elements used in cutting tool materials and their properties are Element Properties Tungsten Increases hot hardness Hard carbides formed Abrasion resistance Molybdenum Increases hot hardness Hard carbides formed Improving resistance Chromium Depth hardenability during heat treat hard carbides are formed improving abrasion resistance some corrosion resistance Vanadium combines with carbon for wear resistance retards grain growth for better toughness Cobalt Increases hot hardness, toughness Carbon Hardening element forms carbides Different cutting tool materials used for cutting operations in practice are high carbon steel, high speed steel, non -ferro

Alloying elements are used to alter the mechanical and chemical properties of steel to give them advantages over standard  carbon steel . While there are many alloying elements used to achieve various enhanced properties, certain elements are much more common than others. These are 5 common alloying elements: 1. Chromium Chromium Chromium added to carbon steel in percentages usually greater than 11% creates stainless steel. At this percentage and greater, the corrosion resistance of a steel vastly increases and oxidation of the iron is prevented in many conditions. The iron does not oxidize because the chromium will oxidize first and form a protective layer over the steel. Chromium also helps to improve mechanical properties, even in smaller amounts. It will increase the steel’s strength, hardness, and ability to be heat treated. Common steels with high amounts of chromium include grades 439, 309, 2205 stainless steels. Grade D2 tool steel also has significant amounts of chromiu

What is oil  O1  Steel?  AISI /  ASTM A681  O1  tool steel  is a low alloy cold work tool steel that must be oil-quenched in heat treatment. Tools and dies made from O1 tool steel flat or rounds will have good wearing and abrasive qualities since the tungsten and higher chromium content gives improved wear resistance. ASTM O1 tool steel has deep hardening properties with fine grain structure with unusual toughness. AISI O1 tool steel offers good durability, gives excellent wear resistance and holds a good cutting edge. O1 cold work tool steels also have a good response to heat treatment with small dimensional changes. We are a better choice of O1 oil tool steel materials supplier with reliable quality and sales service. AISI Tool steel O1 is available in standard de-carb free rounds, flats, and squares, as well as the largest size selection in O1 oil steel ground flat stock and drill rod of all the tool steel grades, or as per customized requirements. 1.

AISI  8620 Steel  is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as-rolled condition with a maximum hardness of HB 255max. SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant. AISI 8620 steel has a higher core strength than grades 8615 and 8617. SAE 8620 alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. Pre-hardened and tempered (un carburized) 8620 can be further surface hardened by nitriding but will not respond satisfactorily to flame or induction hardening due to its low carbon content. Steel 8620 is suited for applications which require a combination of toughness and wear resistance. This grade is commonly supplied in round bar. 1. AISI 8620 Steel Supply Range 8620 Round Bar: diameter 8mm – 3000mm 8620 Steel Plate: thickness 10mm – 1500mm x width 200mm – 3000mm 8620 Square Bar: 20mm – 500mm 8620 tubes are also availabl
