CS Heavy Forgings supplies H12 and H13 tool-steel forgings for dies, tooling, inserts and selected hot-work components used in forging, extrusion and other high-temperature manufacturing operations.
H12 and H13 belong to the chromium-molybdenum hot-work tool-steel family. Grade selection should consider thermal fatigue, hot strength, toughness, wear, section size and heat-treatment practice. These grades should be marketed primarily for tooling and hot-work components rather than as general-purpose shaft or crankshaft steels.
Review the broader steel grades for heavy forgings guide before comparing material families. Final selection remains the responsibility of the purchaser or component designer and must follow the complete drawing and specification.
Target applications
- Forging dies and tooling components
- Extrusion and hot-work tooling
- Die inserts, blocks and support components
- Selected high-temperature rolls and wear parts
Custom forging and supply options
Enquiries can be reviewed for as-forged, heat-treated, rough-machined or finished-machined supply according to the drawing. State the required material condition, machining allowance, tolerances, surface requirements and inspection stage when requesting a quotation.
Relevant CS Heavy Forgings capabilities include flats and die blocks, forgings for die-forging units, extrusion-tool forgings.

Frequently asked questions
Are H12 and H13 ordinary alloy steels for shafts?
They are hot-work tool steels designed around tooling requirements such as hot strength, toughness and resistance to thermal fatigue. They should only be used for a shaft when the engineering specification explicitly requires that grade.
What information is required for an H13 forging enquiry?
Provide the exact standard, drawing, starting and finished dimensions, delivery condition, hardness, heat treatment, machining, ultrasonic testing and quantity.
