Eternal
105V (ISO numeric designation 1.2834) is a high-carbon, micro-alloyed cold-work tool steel made according to the standard ISO 4957:2018 Tool Steels. It falls under the group of unalloyed or low-alloy cold-work tool steels.
This material is suitable for cold-work applications where the surface working temperature is generally below 200°C. It offers a good combination of:
excellent hardenability,
good wear resistance,
and good toughness
Element | Content(wt%) | Description |
C | 1.00 – 1.10 | Ensure high hardness and wear resistance after quenching |
Si | 0.10 – 0.30 | Decarburizing agent, enhances hardenability |
Mn | 0.10 – 0.40 | Improve hardenability to enhance strength and hardenability |
P | ≤ 0.030 | Harmful elements, strictly controlled |
S | ≤ 0.030 | Harmful elements, strictly controlled |
V | 0.10 – 0.20 | Refine the crystal grains to enhance the wear resistance and toughness |

Electric arc furnace (EAF) + LF refining + VD vacuum degassing. For high-end requirements, electroslag remelting (ESR) can be adopted to enhance purity.
The initial forging temperature is 1020℃, and the final forging temperature is 800℃.
Carburizing annealing (slow cooling at 750–800℃) results in a uniform spheroidized pearlite structure, improving the machinability of the material.
Our goal is to work closely with partners to help customers achieve greater success in multiple fields.
Inspection certificate 3.1 or 3.2 in accordance with ISO 10474 is available upon request.
Brinell hardness test per ISO 6506-1; Rockwell hardness test per ISO 6508-1.
Non-destructive testing (NDT) can be performed in accordance with ISO 17577 (acceptance class B1).
Hot-rolled bars meet surface class A per ISO 9443; plates comply with ISO 7788.
