Description
H21 Round Bars / DIN 1.2581 Round Bars
H21 Round Bars Sae / AISI H21 Tool Steel is a high quality Hot work tool steel, It belong to the high quality high carbon alloy tool steel. Oil Quenched & Tempered Hardenss is 28-34 HRc. AISI H21 steel Annealing delivery hardenss less than 250HB.
SAE H21 / AISI H21 Steel is a tool steel. H21 is the designation in both the SAE and AISI systems for this material. T20821 is the UNS number Tungsten Hot-Work Steel.
H21 Steel is a hot work tool steel for oil or air hardening to develop high hot quality, support of hardness, and warmth checking resistance.This is mostly utilized as hot work devices, instruments for manufacture of hollows, screws, rivets, nuts bolts. Die casting tools, forming dies, die inserts, hot shear blades.
ASTM AISI H21 tool steel, we can supply the round bar. AISI H21 steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces.
We Textron Steel & Alloys is the biggest Stockiest & Supplier of Hot Work Steel AISI H21 Round Bar.
Tungsten hot work tool steels are of different types, namely, H21 to H26 types. These hot work tool steel have similar characteristics to that of high speed tool steel. The primary alloying elements in tungsten hot work tool steel include tungsten, chromium, carbon, and vanadium. They are resistant to distortion when they are air hardened, and have higher hardening temperature when compared to chromium hot work tool steel. Breakage of the tungsten hot work tool steel can be reduced if they are preheated to operating temperature before use. Thermal shock resistance and toughness of these hot work tool steel can be improved by reducing the carbon content.

Applications of H21 Round Bar :
H21 hot work tool steel is particularly useful for hot forging and blanking dies and punches for making nuts, bolts and other similar small components. Dies, cores, inserts, pins, etc for the die casting of copper base alloys are also prime applications for this steel. Other uses include forming dies, shear blades, hot extrusion dies, mandrels, punches, die holders, ejector discs and extrusion liners. AISI H21 tungsten hot-work tool steels are mainly used for hot-working dies and toolings, e.g., die casting, extrusion and hot-forming of parts.
