1350H19

1350H19 is a designation used in certain steel catalogs to denote a hot-work tool steel in the H19 family. This class of alloys is intended for tooling that operates at elevated temperatures, such as dies and molds used in stamping, extrusion, and hot forming processes. The exact meaning of the 1350 prefix is not standardized across manufacturers and generally reflects a vendor-specific catalog number rather than a universal chemical specification.

Composition and properties of 1350H19 are derived from the H19 hot-work steel alloy, but the precise chemical makeup can vary by supplier. Consequently, the material’s mechanical properties—such as hardness, toughness, and thermal shock resistance—are also dependent on the heat-treatment regime applied by the producer. In practice, hot-work tool steels in this family are treated to achieve high hardness at elevated temperatures while maintaining sufficient toughness, with common heat-treatment routes involving austenitizing, quenching, and tempering to target hardness levels.

Applications for 1350H19 align with typical hot-work tooling needs. It is used for components that must withstand repeated exposure to high temperatures and slugging forces, including dies for metal stamping, extrusion tooling, and other mold and die applications where thermal resistance is important.

Availability and standards for 1350H19 are supplier-specific. There is no single international standard that universally defines this exact designation. For reliable specifications, performance data, and heat-treatment guidance, engineers should consult the exact datasheet provided by the relevant manufacturer or supplier.
