How to use the table

Enter the steel grade in the search field - in any format: Cyrillic (40Х, ШХ15, 45, Р6М5), Latin (42CrMo4, 4140, H13, 316L) or by W.Nr. (1.7225, 1.2379). The tool searches for a fragment simultaneously in all standards. Refine your search using filters: material group, ISO processing class (P/M/H) or main standard.

The “CSV (filter)” button uploads filtered rows - convenient for specifications and queries.

Database covers

Structural steels (ISO P): carbon (45, C45/1.0503/1045), improved alloy (40Х, 40ХН2МА, 42CrMo4/1.7225/4140/4340), cemented (16MnCr5, 18CrNiMo7-6), spring-spring (51CrV4/6150, 60С2А/9260, 65G), nitrated (31CrMoV9, 41CrAlMo7).

Tool steels (ISO H): cold forging (Х12МФ/D2/1.2379, 9ХС/O2*), hot forging (H13/1.2344, H11/1.2343), bearing (ШХ15/100Cr6/52100/SUJ2), high-speed (Р6М5/M2/SKH51, Р6М5К5/M35).

Stainless steels (ISO M): austenitic (304/304L/316L/321), ferritic (430), martensitic (420, 440C), precipitation-hardening (17-4PH/1.4542).

Frequently Asked Questions

Why is UM% (Ultimate Machinability) important? It is relative machinability compared to the benchmark (1112/12L14 = 100%). Affects the choice of cutting modes, speed and tool. The higher the UM%, the better the machinability.

What does ISO P/M/H mean in the table? Classification according to ISO 513 for choosing a tool alloy: P - steels, M - stainless steels, H - hardened and tool steels. Linked to the Alloy Analogue calculator.

Is it possible to directly replace one brand with an analogue? The correspondence is “closest”, not always complete. Before replacing, check the chemical composition, delivery condition (Q+T/Annealed), HB/HRC hardness and drawing requirements.
