Products Description
DIN 1.2355 tool steel is a Shock-Resisting Steel with the highest hardenability and elevated temperature softening resistance of the S-series steels. Due to these properties, S7 material is popular in shock-resistant applications. They are moderately resistant to decarburization and grain growth.
Product characteristics
1. High impact toughness, good wear resistance
2. Excellent toughness under high strength
3. High hardenability and softening resistance
4. Excellent mechanical fatigue resistance
1.2355 Steel Applications
Mak impact and softening resistant tools, such as: tool industry - punch, forging die, hammer, chisel, clamp die, cutting tool, sword;
Also Suitable for impact tools and plastic moulds for hot and cold work.
