Forged Mold Steel – Precision, Durability, and High Performance for Mold Manufacturing
Overview:
Forged mold steel is a high-performance material designed for the creation of molds in industries like automotive, plastics, aerospace, and more. This steel is processed through a forging technique, enhancing its mechanical properties and providing superior performance compared to traditional cast steel. Known for its durability and precision, this material is ideal for producing molds that withstand rigorous conditions, ensuring high-quality results over long production cycles.
Key Features:
High Strength and Durability: The forging process significantly improves the material’s strength, making it resistant to wear and capable of handling demanding applications without degradation over time.
Excellent Toughness: This steel is designed to endure high levels of stress and impact, making it ideal for situations where molds are exposed to extreme temperatures and pressures.
Thermal Resistance: Forged steel maintains its integrity under high temperatures, offering resistance to thermal shock and heat deformation. This makes it particularly suitable for processes like injection molding and die casting.
Precision and Stability: Molds made from this material retain their shape even under varying conditions, ensuring accurate parts with minimal dimensional changes throughout production.
Corrosion Protection: While not as corrosion-resistant as stainless steel, forged steel can be treated to provide added protection, extending the lifespan of the mold in tough environments.
C45 steel is an unalloyed medium carbon engineering steel which has 0.42%-0.5% Carbon. It offers moderate tensile strengths, wear resistance and good machinability. this material is capable of through hardening by quenching and tempering on limited sections, and also can be flame or induction hardened to surface hardness Min 55HRC. C45 is generally supplied in an untreated or normalised condition with a typical tensile strength range 570 – 700 Mpa and Brinell hardness range 170 – 210.
