Technical Specifications and Heat Treatment Capabilities
Milano Special Steel provides comprehensive technical support to help customers optimize the performance of EN31 steel through appropriate heat-treatment processes. Standard heat treatment for 100Cr6 steel involves austenitizing at 830-860°C, followed by quenching in oil or salt bath, and tempering at 150-180°C to achieve hardness levels between 58-64 HRC. This quenched-and-tempered condition provides the optimal combination of hardness, wear resistance, and toughness for bearing applications.
For applications requiring deep hardening, such as large bearings or heavy-duty rollers, Milano Special Steel can recommend modified compositions or alternative heat-treatment cycles to maintain high hardness throughout the component. The thermal conductivity of EN31 steel at various temperatures—approximately 44.5 W/(mK) at 20°C, 45.0 W/(mK) at 350°C, and 46.0 W/(m*K) at 700°C—influences heat treatment uniformity and must be considered when processing larger cross-sections. Our technical team provides guidance on annealing treatments to improve machinability before the final heat treatment.
Quality Assurance and Material Certification
Every EN31 steel plate and round supplied by Milano Special Steel undergoes rigorous quality control testing to verify chemical composition, mechanical properties, dimensional accuracy, and surface condition. We provide complete material test certificates documenting carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, and copper content in accordance with JIS G4805, AISI/SAE, EN ISO 683-17, and other applicable standards. Mechanical property certifications include hardness testing per ASTM E18, tensile testing, and impact strength testing per ASTM E23.
Our commitment to quality extends beyond standard certifications to include advanced testing capabilities for critical applications. Non-metallic inclusion ratings, grain size analysis, and decarburization depth measurements ensure that aerospace and high-reliability bearing applications receive material of exceptional purity and uniformity. Third-party inspection and certification services are available to customers who require independent verification of material properties and compliance with international standards.
