H1 Tool Steel Chemical Composition Properties, Grade, Chart and Online Pdf
H1 tool steel is a robust and resilient tool for industrial use that is superbly resistant to various wear and tear, thus suitable for many applications. A typical carbon percentage varies from 0.4%, while the chromium composition is about 5.25%, vanadium is 1.3% and other minor alloying elements like manganese, silicon, and molybdenum. In this case, the chromium provides for a solid carbide that is highly hard, strong in abrasion resistance, and somewhat tough. Machine tool steel H1 is typically applied in cutting tool manufacturing, dies, and machinery parts where utmost wear resistance, dimensional stability, and operational precision are needed. The quality of the product is improved when the heat application is done by a carefully controlled heating process. Engineers and manufacturers frequently resort to sources of comprehensive table, charts and online materials to find exactly what information they need about the H1 tool steel grades and their specifications.
H1 Tool Steel Chemical Composition And Grade Table
H1 tool steel is a chromium-based steel, with its predominant usage being its outstanding toughness and wear resistance, which places it in a unique position to serve in high-stress tooling and machinery. Its chemical composition resembles 0.40% carbon, 4.75% chromium, 1.0% vanadium, and 0.55% to 2.05% molybdenum, tungsten, and manganese. H1 steel belongs to the group of high carbon, high chromium steels lists in the H series-almost same as other tool steels. The grade table in its table demonstrates it's usefulness for cutting tools, dies, punches and other tools where toughness and hardness is of prime importance.
