h21 tool steel
Aug 13, 2021 · H21 (3Cr2W8V) steel has been applied widely to manufacture various types of hot-work dies. It has high thermostability and hot strength, suitable heat treatment, good castability, and forgeability [
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 H21 / AISI H21 / DIN 1.2581 Die Steel and Tool 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 and bolts. Die casting tools, forming dies, die inserts, hot shear blades.
H21 is a hot work tool steel suitable for applications where red hardness, high compressive strength and wear resistance at elevated temperatures are required. These features together with good impact resistance provide a steel with excellent properties for general purposes, hot working conditions. Preheating prior to use in service will considerably improve tool life. H21 Steel DIN 1.2581 Hot Work Tool Steel Verified China 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.
H21 tool Steel there are different types of tungsten hot work steels like, H21 to H26 types. They are resistant to deformity when they are air-hardened. Have better hardening temperature while in comparison to chromium hot-work steels. X30WCrV9-3, 1.2581, Z30WCV9 - tool steelX30WCrV9, 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
