At Hopman Machinefabriek B.V., we work with a wide range of materials to meet the diverse needs of our customers. Today, we take you into the world of five commonly used materials: S355J2, S355J2+N, 42CrMo4+QT, 34CrNiMo6, and C45. Each of these materials has unique properties and applications, and we are happy to explain what makes them so special.
S355J2 (1.0577)
Application: S355J2 is a non-alloy structural steel widely used in construction and heavy structures. It offers a good combination of strength and toughness, making it ideal for bridges, buildings, and other structural applications.
Machinability: This material has reasonable machinability but may cause tool wear due to the presence of hard inclusions. It is important to use the right tools and cutting parameters to achieve optimal results.
S355J2+N (1.0577)
Application: S355J2+N is similar to S355J2 but is supplied in a normalized condition. This means the material has improved consistency and mechanical properties, making it suitable for critical structural applications.
Machinability: The normalized condition slightly improves machinability, making it easier to process than standard S355J2. This makes it a popular choice for applications where precision and reliability are crucial.
42CrMo4+QT (1.7225)
Application: 42CrMo4+QT is an alloyed steel commonly used for components requiring high strength and toughness, such as shafts, gears, and heavy machine parts. It is hardened and tempered to achieve optimal mechanical properties.
Machinability: This material has good machinability, especially in the tempered condition. However, it can be more challenging to machine than non-alloy steels, so it is important to use the right cutting tools and coolants.
34CrNiMo6 (1.6582)
Application: 34CrNiMo6 is a high-quality alloyed steel used for highly demanding applications such as aerospace components, heavy machinery, and tools. It offers excellent strength and toughness, even at low temperatures.
Machinability: This material has reasonable machinability but requires careful tool selection and machining parameters to achieve optimal results. Maintaining the correct cutting conditions is essential to minimize tool wear.
C45 (1.0503)
Application: C45 is an unalloyed quenched and tempered steel widely used for components requiring higher strength and wear resistance, such as shafts, gears, bolts, and nuts. It is also popular in tool and machine construction.
Machinability: C45 has good machinability in a normalized condition but can be more difficult to machine after heat treatment. It is essential to use the right cutting tools and machining parameters to achieve optimal results.
Each of these materials offers unique benefits and applications, depending on the specific requirements of your project. Do you have any questions about which material best suits your needs? Feel free to contact us!
