Why are there material numbers for steel?
In an international context it is important that steel designations can be understood clearly and independently of the trade name. While for example ‘1.2312’ has the same meaning globally, the trade name may differ depending on the manufacturer.
The material number:
creates clarity,
facilitates comparability,
enables international classification,
prevents incorrect orders.
The first digit: The main material group
In mould and die making, the most commonly used material is steel, which is classified as material group ‘1’. This is why our list of materials is made up almost entirely of material numbers that start with a 1; only two aluminium materials start with a 3:
0 = crude iron
1 = steel
2 = non-ferrous heavy metals
3 = non-ferrous light metals
4–8 = non-metallic materials
The steel group number
The steel group number distinguishes between unalloyed and alloyed steels. Both steel groups are divided within their respective groups into high grade steel and stainless steel.
The sequential number
Within a steel group each steel is given a specific sequential number, which ultimately allows the material to be clearly identified. The complete steel material number is assigned by the Steel Institute VDEh in Düsseldorf.

Meusburger steel grades at a glance
As a standard parts manufacturer it is of central importance to us to make the right steel grade for almost every application available. Because selecting the right material is dependent on many factors such as load, environment and function.
Cold-work steels
Cold-work steels are used for moulds which generally don’t reach temperatures higher than 200 °C while in operation.

Hot-work steel
The continuous operating temperature of hot-work steel is over 200 °C, which is why hot-work steel offers the best properties for die casting moulds as well as moulds with which high performance plastics are worked.
Hot-work steel from Meusburger
| 1.2343 / 1.2343 ESR | Hot-work steel | Cavity plates and inserts for plastic injection moulds; *ESR for die casting applications (Al, Mg, Zn) |
| 1.2344 / 1.2344 ESR | Hot-work steel | Standard material for hot-work tools, extrusion dies, dies, moulds for plastic processing |
| 1.2714 | Steel for through hardening | Extrusion dies, hot-forging tools, die plates for processing tin, lead and zinc alloys |
Steel for quenching and tempering
Thanks to their carbon content between 0.20% and 0.65%, these steels are especially suited for quenching and tempering through heat treatment, which results in an optimum combination of strength and toughness.
Steel for quenching and tempering from Meusburger
| 1.7225 | Steel for quenching and tempering | Jigs and fixtures, base plates, axes, gear shafts, gear wheels |
High-speed steel
High-speed steel, or HSS for short, is a high-alloy tool steel with large amounts of alloying elements such as tungsten, molybdenum, chromium, and vanadium. They offer high resistance to adhesive and abrasive wear with high toughness as well as high resistance to pressure and high temperatures.
High-speed steel from Meusburger
| 1.3343 (HSS) | High speed steel (HSS) | Blocks for eroding, cold-forming tools such as cutting or fine blanking punches, impact extrusion punches, and die plates Mould inserts with very high wear resistance |
| 1.3344 PM | Powder metallurgical steel | Blocks for eroding, cutting punches and die plates with maximum edge stability Mould inserts with maximum wear resistance |
| M CR8 PM | Powder metallurgical steel | Blocks for eroding, die plates and cutting punches with high requirements on compressive strength, pressure and form rolls, thread rolling dies, impact extrusion punches and embossing tools |
| M V10 PM | Powder metallurgical steel | Blocks for eroding, die plates and cutting punches with extreme requirements, fine blanking punches, pressing punches for sinter press tools |
| M W10 PM | Powder metallurgical steel | Blocks for eroding, die plates, cutting punches and cutting tools for extremely high requirements, fine blanking punches, embossing tools, cold solid forming |
Steel for case hardening
Due to the low carbon content of steels for case-hardening, they are ‘inserted’ into an atmosphere with high carbon content and heated. The result is a piece with high core toughness and surface hardness.
Steel for case hardening from Meusburger
| 1.2162 | Steel for case hardening | Machine parts and cavity plates with a high surface hardness, synthetic resin press moulds for the processing of thermoplastics and thermosetting plastics |
| 1.7131 | Steel for case hardening | Machine parts and cavity plates with a high surface hardness, synthetic resin press moulds for the processing of thermoplastics and thermosetting plastics |
Steel for through hardening
Steels for through hardening are delivered in a soft condition. They are good for further hardening processes, in order to change the mechanical properties of the steel.
