Material Description: Unalloyed mould steel, readily machinable, surface hardenable. The difference from C 45 steel is that it has a cleaner and homogeneous microstructure due to the normalization process.
Chemical composition:
(Typical analysis in %)
| C | Si | Mn | P | S |
| 0,42 – 0,50 | 0,15 – 0, 40 | 0, 60 - 0,80 | ≤ 0,03 | ≤ 0,03 |
Steel properties: High machinability and weldability, Surface can be hardened up to 57 HRC, It has high metal removing property.
Applications: Mould plates for plastic moulds, injection mold and dies, hand tools, agricultural
Condition of delivery: Normalized, annealed 180 – 220HB.
