2 Applications

This steel is ideal for large plastic molds that have deep engravings and endure significant impacts on their cores. The evolution of pre-hardened Plastic Mold Steel, like P20+Ni, is a logical step for developing robust molds that require high core strength. The nickel inclusion (1%) enhances hardening capabilities. Formadur, known for being a micro-alloyed, vacuum-degassed steel, presents remarkable features such as excellent machinability, exceptional polishability, and great texturing properties.

mold steel is primarily utilized in low-temperature applications like die casting and injection molds. It is particularly advantageous for manufacturing large plastic molds that are highly stressed in the core, including hydroforming tools capable of handling dimensions up to 400 mm.

DIN 1. steel is classified as a type of plastic mold steel, equivalent to AISI P20+Ni tool steel. Nickel, chromium, and molybdenum serve as alloying elements that contribute to enhanced hardness and toughness. This steel is specifically designed for the plastic mold industry, particularly in the production of larger steel mold components.

Typically supplied in a pre-hardened condition with a hardness level of 280 to 320 HB, DIN 1. steel provides superior machinability and better polishability compared to the standard AISI P20+S. The material can undergo nitriding and flame hardening treatments to enhance the hardness and wear resistance of the mold surface. The melting process occurs in an electric furnace, refined through VOD or DH methods.
