AISI H21 is a hot work tool steel for oil or air solidifying to grow high hot quality, maintenance of hardness and warmth checking resistance. This is mostly utilized as hot work devices, instruments for manufacture of hollows, screws, rivets, nuts and bolts. Annealed H21 Tool Steel ::MakeItFromMay 30, 2020 · Annealed SAE-AISI H21 is SAE-AISI H21 steel in the annealed condition. The graph bars on the material properties cards below compare annealed SAE-AISI H21 to:tool steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is
Tool Steels & Die Steels refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). Tool steel is generally used in a heat-treated state. H21 - Walter MetalsOct 02, 2013 · H-21 is perhaps the most widely used of the Tungsten hot work steels. The 9.5% tungsten content imparts good resistance to softening at service temperatures while still maintaining adequate toughness. Unlike the higher tungsten grades, H-21 may be cooled by continuous flow of water if the design of the die will permit. H21 Round Bar, Hot Die Steel, Tool Steel, Working SteelH21 / 2581 Steel has about 2.5-3.2% Chromium, 8.5-9.5% Tungsten, 0.3-0.5% Vanadium. Thermal shock resistance and toughness of DIN 1.2581 steels can be improved by reducing the carbon content. SAE H21 Hot Working Tool Steel Bar can be avail as Concast (CC), Rolled, Forged in normalized, spheroidized annealed, hardened (quenched) & tempered
2 H21 Steel Applications: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. Most Common Tool Steel Grades with Applications - Fushun Feb 24, 2021 · Oil Hardening tool steel or O-Grades (Cold-Working) This tool steels group has great resistance to abrasion and high toughness properties. It is considered to be a general-purpose steel, making it very versatile. Like 1.3520, 1.2419, O2, O1 Most of the applications are similar to those of A-grade and D-grade tool steels, but also include:Bushings Wear and Fatigue Behaviour of Deep Cryogenically Treated Nov 07, 2019 · The AISI H21 tool steel is widely used to manufacture hot forging and hot extrusion dies for non-ferrous metals. In these applications, dies are exposed to high impact load, thermal conditions and contact pressure. Such working conditions may increase the surface roughness, wear rate and decrease the fatigue strength of the hot forging die.
X30WCrV9, 1.2581 steel is used as:Steel for high-load dies for making bolts, nuts and rivets. Steel for presses for extruding rods. Steel for inserts for dies and stamps. Steel for extrusion tools. Steel on matrices for extrusion of copper alloys. Steel for knives for hot-working scissors. Steel on the dies for pressing and forging hot brass h21 tool steel, h21 tool steel Suppliers and Manufacturers A wide variety of h21 tool steel options are available to you, such as aisi, astm, and jis. You can also choose from bending, cutting h21 tool steel, as well as from tool steel bar, structural steel bar, and die steel bar h21 tool steel, and whether h21 tool steel is is alloy, or non-alloy.H21 - Ellwood Specialty SteelOct 02, 2013 · H21 is perhaps the most widely used of the Tungsten hot work steels. The 9.5% tungsten content imparts good resistance to softening at service temperatures while still maintaining adequate toughness. Unlike the higher tungsten grades, H-21 may be cooled by continuous flow of water if the design of the die will permit.
