Carbon steel
- Low carbon cold forming steels, micro-alloyed steels, case hardening steels,
quenching and tempering steels, spring steels and special steels.
Carbon steel, as the name suggests, has a proportion of carbon in its alloy. The carbon content is controlled to give unique properties to different types of steel, making it popular for a variety of applications.
We have a very wide range of different carbon steels. We deliver in both coil, ring and also in lengths or sheets. See edge designs below.
Edge designs
All steel grades can be supplied with cut edge, planed round, planed straight, profile planed edge. Round edge may be preferable for a dynamically loaded spring, i.e. a spring subjected to a large number of load cycles. Round planing removes most of the minimal edge defects normally found on a cut edge and a round edge normally results in a longer service life for fatigue loaded springs with alternating or pulsating loading
Isotropic bands - gives you advantages in deep drawing.
The mechanical properties differ slightly along and across the rolling direction in cold-rolled strip steel, known as anisotropy. This can result in e.g. ear formation during deep drawing. Furthermore, the shape tolerances can be negatively affected. Our NZ strip has been given a very high degree of isotropy via continuous annealing, i.e. the properties along and across the rolling direction are almost identical. Even the grain structure of the material has advantages, allowing you to eliminate polishing. NZ strip gives you advantages in deep drawing. NZ strips give you advantages in deep drawing.

Carbon steel in different ways
Case hardening steel
Case hardening gives steel a hard surface that is resistant to wear and abrasion. In case hardening, carbon is added to the surface, causing the surface to harden. The core still has a low carbon content and remains soft after case hardening, which means you get a steel with good toughness.
Low carbon steels for cold forming
Low carbon steel cold forming has a low carbon content, relatively low strength with a high elongation at break giving it very good formability. It can be bent into tight radii and also used for deep drawing. The low carbon content also makes it suitable for welding.
Quenching and tempering steel
Quenched and tempered steels have a higher carbon content than quenched and tempered steels and take hardening without adding carbon during the hardening process and become through-hardened. Quenched and tempered steels are able to withstand high stresses and are used, for example, for edge applications and certain types of resilient components.
Micro-alloyed steels
By adding small amounts of micro-alloying elements such as niobium, titanium or vanadium, low-carbon steels can achieve higher strength and good formability. The low carbon content means that the material is easy to weld. Our special steel RAWAEL is a micro-alloyed steel with the possibility of high strength up to 1200 MPa. In some applications, it can replace case-hardened steel while maintaining tight dimensional tolerances thanks to the elimination of hardening.
Spring steel
Spring steel can be used for edge applications, various types of knives, saws, springs, etc. The strip steel or plate can be supplied in annealed condition for hardening after punching/forming. The strip can also be supplied in a pre-hardened condition. Formability in the martensitic hardened condition is severely limited. However, we can also supply bainitic hardened spring steel with high strength combined with good formability. This steel is called PT-BAND and replaces case hardened components.
