H10 is a molybdenum hot-work tool steel from ASTM A681. With 2.5-3.5 % molybdenum and lower chromium than the H11/H13 family, it combines high hot hardness with good toughness — used for hot-forging dies, punches and die inserts subjected to heavy mechanical load at elevated temperature.

Hot forging — forging dies, punches, die inserts for hammer and press
Extrusion — extrusion tooling subjected to heavy load
Die casting — die-casting dies where higher toughness than H13 is needed
Punching — hot punching and piercing tools
H10 is hardened from 1000-1040 °C in air and double tempered at 540-620 °C. The molybdenum content gives good hot hardness and resistance to thermal fatigue. Double tempering is required to transform retained austenite and stabilise dimension.
Most suppliers in this business are traders who subcontract everything. We run our own processes, which means shorter cycles and one point of accountability when something needs fixing.
Heat treatment shop — quenching, tempering and vacuum heat treatment to your target hardness, with furnace charts recorded per batch
Machining shop — rough turning, peeling, milling and cutting to length, so your bar or block arrives ready for finish machining
Testing — ultrasonic per ASTM A388 / EN 10228-3, hardness mapping across the section, microstructure on request
Certification — EN 10204 3.1 as standard, 3.2 available with third-party witness (ABS, BV, CCS, GL)
Export packing — bundled, end-capped and rust-protected for sea freight
H10 is a molybdenum grade (2.5-3.5 % Mo) chosen when higher toughness is needed at the working temperature than the H13 chromium grade provides. H13 is more common for die casting; H10 is preferred for heavy-load forging punches and inserts. See our H13 page.
Yes. We quench and temper in our own shop to your target hardness, with hardness mapping and furnace charts.
EN 10204 3.1 mill certificate as standard. 3.2 with third-party witness on request.
