DC01 – DC06, DD11 – DD14, S235JR, S355JR, E295, E355
Dimensional spectrum:
- thickness: 1,00 – 13 mm
- width: 30,00 – 650 mm
Properties
- Many implementation options in hot and cold strip possible – levelled, annealed or cold-rolled
- High flexibility in scope of application
- Special deep drawing properties of cold-rolled grades DC01 – DC06 [especially in LC versions with a rising trend]
- Good to very good weldability due to a low concentration of the alloying elements
- Improved corrosion resistance due to surface treatments like galvanizing
HC260LA – HC420LA, S260MC – S700MC
Dimensional spectrum:
- thickness: 1,00 – 10 mm
- width: 30,00 – 650 mm
Properties
- High-strength steel – tough and fine-grained, can be formed and welded
- Limited carbon content to increase the strength to max. 0,2% / no reduction of the toughness and weldability
- Increased toughness by adding manganese, chrome and Molybdan / tensions in the ferritic atomic lattice
- Further increased stability through age-hardening [addition of aluminium, titanium, niobium or vanadium]
C10E, C15E, 15Cr3, 17Cr3, 16MnCr5, 20MnCr5, 15CrNi6, 17CrNiMo6
Dimensional spectrum:
- thickness: 1,00 – 12 mm
- width: 30,00 – 650 mm
Properties
- Low carbon steel [C < 0,25%] for case hardening – complex formed workpiece with a wear resistant surface and a tough core
- Execution of geometrically complex forms, as materials in a soft annealed condition exhibit an ideal tensile strength ratio
- Targeted enrichment of the surface with carbon combined with heat treatment / high hardness around the edges
C22E – C60E, 46Cr1, 25CrM04 – 42CrMo4, 50CrMo4, 22MnB4 – 40MnB5, 27MnCrB5-2
Dimensional spectrum:
- thickness: 1,00 – 12 mm
- width: 30,00 – 650 mm
Properties
- Similar to case-hardening steels – improved wear resistance as it obtains its hardness over the entire cross section
- Increased toughness by adding manganese, chrome and Molybdan / tensions in the ferritic atomic lattice
- Limited carbon content to increase the strength to max. 0,2% / no reduction of the toughness and weldability
- Carbon steels with min. 0,25%, which are refined by adding other alloying elements such as molybdenum, chrome, nickel, manganese; increased hardening depth [chrome] or increased thermal resistance [nickel]
- The first step [hardening] includes a change of the martensite microstructure / hard and tough structure; in the second step [tempering] the hardness is reduced / the toughness is increased
C55S – C100S, 75Cr1, 51CrV4, 58CrV4, 80CrV2, 48Si7, 56Si7, 75Ni8, 125Cr2, 102Cr6
Dimensional spectrum:
- thickness: 1,00 – 12 mm
- width: 30,00 – 650 mm
Properties
- Special group of Q & T steels – higher elasticity and tensile strength by adding chrome, vanadium and silicon; grain refinement and sinking critical rate of cooling
- The combination with a clean, cold-rolled surface texture results in a considerable improved endurance resistance
- Flat steel diaphragm spring [51CrV4 / 58CrV4] gain a more effective storage of work capacity
