A2 Tool Steel Chemical Composition Properties, Grades, Charts and PDF Online
A2 tool steel steel enjoys a stellar reputation for its outstanding roller-resistance, hardness and versatility across a wide range of industrial settings. Chromium steel is a carbon steel alloy that often composes of 1.00% carbon, 5.00% chromium, 1.00% molybdenum and 0.30% of manganese. Its high chromium content confers to it excellent corrosion and edge retention characteristics, as well as its very reason why it is a good material for tooling and precision instruments. This kind of steel is typically of heat-treatment nature, which is then hardened and toughened in order to achieve a fairly high hardness, around 60 to 62 in HRC after quenching. Due to its chemical structure the A2 steel is used for making a high variety of tools like the dies, cutting tools and it can also be used for the various operations of punching, forming and stamping. Online graphs and the PDF's are available to everyone in the website for detailed reference of A2 tool steel properties and grades.
A2 Tool Steel Chemical Composition And Grade Table
A2 tool steel, with its superior wear resistance and a decent level of toughness, has become an excellent choice for tooling due to its wide application. The material is usually made up of carbon, chromium, manganese, silicon, molybdenum, vanadium and phosphorus, each present in percentages of 1.00% carbon, 5.25% chromium, 1.00% molybdenum, 0.30% manganese, 0.30% silicon, Beside it also has sulfur and copper in smaller quantities. Thus, A2 steel, apart from possessing remarkable cutting edge and stability during heat treatments, enjoys such a premium. A2 is included in the ASTM A681 standard that has air-hardening property and is characterized as medium-alloy, cold-work tool steel grade.
