H13 (Hot Work) — Machining & Properties
Typical properties, what H13 (Hot Work) is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.
Machining H13 (Hot Work)
Machinability is rated difficult — a genuinely demanding material — rigid setups, premium tooling and conservative parameters, with cycle time and tool wear to match. Tool and die steels (H13, D2, M2) are typically rough-machined in the annealed condition, hardened and tempered to working hardness, then finish ground or EDM’d to final dimension. Engaging us early in your design allows the sequence to be optimised for minimum distortion.
Our standard achievable tolerance on H13 (Hot Work) is ±0.020mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Nitriding, PVD, polishing. Full material traceability with MTR and CoC documentation on every order.
Typical applications
Die casting inserts, injection mould tooling, forging dies, extrusion dies.
