5CrNiMo Hot Working Tool Steel Plates: Characteristics and Applications

5CrNiMo hot working die steel plates are a type of high-quality, high-strength, low-alloy structural steel with numerous notable characteristics and a wide range of applications across multiple industrial sectors.
Characteristics
Chemical Composition: The chemical composition of 5CrNiMo steel is meticulously balanced, consisting primarily of carbon (C) at 0.50%~0.60%, silicon (Si) ≤ 0.40%, manganese (Mn) at 0.50%~0.80%, phosphorus (P) ≤ 0.03%, sulfur (S) ≤ 0.03%, chromium (Cr) at 0.5%~0.8%, nickel (Ni) at 1.4%~1.8%, and molybdenum (Mo) at 0.15%~0.30%. These elements collectively contribute to the steel's exceptional properties.
Excellent Mechanical Properties: This steel grade exhibits high strength, high hardness, good toughness, and wear resistance. Its tensile strength is ≥980MPa, yield strength is ≥785MPa, elongation is ≥12%, and impact toughness is ≥55J. After appropriate heat treatment, the hardness can be increased to HRC53~58.
Good Hardenability: Large-sized 5CrNiMo steel materials can maintain uniform hardness across their cross-sections after heat treatment, which is particularly important for manufacturing large, complex-shaped molds.
Insensitive to Temper Brittleness: After slow cooling at 600℃, the impact toughness of 5CrNiMo steel decreases only slightly, broadening its application range.
Good Thermal Stability: At room temperature and temperatures between 500~600℃, its mechanical properties remain almost unchanged, making it suitable for manufacturing molds that need to withstand high temperatures and complex stress environments.
Good Processability and Weldability: 5CrNiMo steel can be welded using common welding methods and exhibits good plasticity and machinability.
Applications
Manufacturing Large and Medium-sized Forging Dies: Such as hammer forging dies, trimming dies, etc. These dies play a crucial role in industrial production, capable of enduring high-intensity impact loads and complex working environments.
Manufacturing Wear-resistant Parts: Utilizing the good wear resistance of 5CrNiMo steel, various wear-resistant mechanical parts can be manufactured.
Manufacturing Parts for High-temperature Operations: With its high thermal stability, 5CrNiMo steel is suitable for manufacturing parts that need to operate in high-temperature environments.
Other Application Areas: Additionally, 5CrNiMo steel can be used to manufacture extrusion dies, die-casting molds, plastic molds, stamping dies, etc., with widespread applications in the automotive, aerospace, machinery manufacturing, and other industries.
5CrNiMo hot working die steel plates occupy an important position in the fields of metal processing and mold manufacturing due to their exceptional performance and wide range of applications.
