H2 tool steel, due to its high content of carbon and chromium, is regarded as a versatile steel, which is known for combined features: exceptional toughness and resistance to wear. It is the most chosen material for industrial applications. In chemical composition, C, Cr, V, and Mo make up the majority components, therefore H2 steels possess exceptional hardness, strength, and less prone to loss of edge. Often following AISI/ASTM A681 or DIN 1.2379 norms, the assortment comes out with various grade designations. Extensive table, charts and PDF files defining its mechanical properties, heat treatment norms, and machinability enable the brochure to be employee friendly. Manufacturers and suppliers, in turn, make use of this information to guide their tooling, cutting, and forming operations. H2 tool steel, as a matter of fact, is an indispensable material in environments where toughness and accuracy are registered on top of the list of requirements.
H2 tool steel, a super tough, high-quality steel widely used especially for cutting tools thanks to its perfect resistance to wear and abrasion, has its chemical composition based on carbon, chromium, molybdenum, vanadium, and silicon. As a rule of the thumb, it is usually comprised of carbon to the extent of 0.9%, 4.0% chromium, 1.0% molybdenum, 0.4% vanadium and 0.4% silicon. It is hardness, strength and abrasion resistance that makes this combination useful for such applications like the cutting tools, punches, dies , and molds. H2 tool steel matches different international standards, like AISI H2, ASTM A681, DIN 1.2363, and JIS SKD12, the examples, ensuring continuous quality and performance.

Advantages:
High Toughness: Resistant to chipping and cracking under impact, suitable for shock-loading operations.
Good Wear Resistance: Sustains high hardness and wear resistance on the surface.
Good Hardenability: Capable of achieving maximum hardness with proper heat treatment.
Good Machinability: Easier to machine compared to some high-alloy tool steels.
Disadvantages:
Moderate Hot Hardness: May soften at high temperatures, affecting tool firmness in hot applications.
Moderate Corrosion Resistance: Requires regular maintenance to prevent corrosion.
Less Edge Retention: May require more frequent honing compared to steels with higher wear resistance.
