H13 Steel

ALL

Product Overview

H13 Steel is a chromium-molybdenum-vanadium hot-work tool steel identified as AISI H13 and UNS T20813, and is publicly associated with ASTM A681. It is documented for hot-work tooling applications, while the specific product form, delivery condition, and premium refining route must be defined separately for the material actually supplied.

Manufacturing & Supply

Attribute	Details
Wrought Manufacturing	ASTM A681-covered wrought alloy tool steel is made by an electric melting process and from ingots reduced sufficiently for refinement of ingot structure.
Gautier Processing	Gautier lists Hot Rolled, Thermal Condition Cycled, Flattened and Cut Ends as standard processes for its H13 steel.
Powder Atomization	Sandvik Osprey H13 powder is produced by inert-gas atomization.

Inspection & Quality

Sandvik Osprey metal powders are supplied with a certificate of analysis containing chemical-composition and particle-size-distribution information.

Key Features & Advantages

Feature	Explanation
Hot-Work Performance	Designed primarily as a 5% chromium hot-work tool steel for elevated temperature tooling.
Alloy Composition	Chromium-molybdenum-vanadium alloying provides resistance to thermal fatigue and softening.
Toughness	Offers high toughness and thermal shock resistance suitable for die casting and extrusion.
Versatility	Used in demanding tooling applications such as forging dies, extrusion tools, and plastic molds.

Applications

Application	Description
Die-Casting Dies	Used for aluminium die casting and die-casting tool applications.
Forging & Extrusion	Employed in hot extrusion tools and forging dies.
Shear & Trim Tooling	Suitable for hot shear blades and trim dies.
Molding Tools	Applied in plastic molds, injection molding, and blanking/forming dies.

Important Notes

Product form is unresolved in the generic catalog identity, spanning wrought material and metal powder. Designations such as EN 1.2344, X40CrMoV5-1, and SKD61 do not automatically imply universal interchangeability without specific manufacturer or standard alignment. Premium ESR variants like Uddeholm Orvar Supreme possess specific properties and quality grades that do not apply to standard generic H13 supply.
