Our Steel Grades Stainless steel
Stainless steel strip for corrosion resistance, formability, and precision—austenitic, ferritic, and martensitic steels in coils, rings, cut-to-length pieces, or sheet metal.
Choose the Right Stainless Steel Strip Chromium provides corrosion resistance
Stainless steel is resistant to corrosion because it contains chromium, which forms a thin layer of chromium oxide on the surface. A chromium content of at least 12–13% is typically required for the steel to be classified as stainless steel.
This makes it well-suited for use in environments where it may be exposed to external factors such as moisture, acids, heat, etc. It is important to select the correct grade of stainless steel depending on the environment to which it will be exposed. Highly corrosive environments require higher-alloyed stainless steels. Stainless steels generally withstand higher temperatures, but even in this case, the correct grade must be selected based on the specific temperature range.
The material has a surface that many people find well-suited for applications where visual appeal is an important factor. It is also hygienic and easy to clean, which is why it is used in the medical, food, and automotive industries.
In this area, we offer stainless steel spring strips/spring steel, acid-resistant strip steel, hardenable martensitic strip steel, and stainless steel strip for both difficult forming and deep drawing. We can supply these products in coils, rings, cut-to-length pieces, or sheets, with cut edges, planed round edges, and other finishes—all according to your specifications.

Our Stainless Steel Three groups of stainless steel
Austenitic stainless steels
Austenitic stainless steels are alloyed with other metals, such as chromium, manganese, and nickel, among others. The material offers good to excellent corrosion resistance combined with very good weldability and formability. This steel is used in applications where there are high demands for spring performance and high strength. Austenitic steel is also common in applications where good formability is important, such as in bending and deep drawing. The austenitic structure offers good creep resistance and good oxidation resistance, making it suitable for use at elevated temperatures. Austenitic steel can also be used in cryogenic applications, i.e., at very low temperatures.
The material is normally nonmagnetic, but becomes weakly magnetic when cold-rolled, such as spring steel 1.4310.
Ferritic stainless steels
Ferritic stainless steels offer good resistance to stress corrosion in particular and are also magnetic. They have good heat resistance and resistance to oxidation. They have a low carbon content and little or no nickel, and do not have the same formability and weldability as austenitic stainless steels. However, weldability can be improved through the addition of alloying elements. Due to their low nickel content, ferritic steels are generally less expensive than austenitic steels and are used primarily in applications where good formability and weldability are of lesser importance—including components in exhaust systems, commercial kitchen equipment, and household appliances such as refrigerators and freezers.
Martensitic hardenable steels
Martensitic stainless steels are hardenable and, after hardening, exhibit high hardness and wear resistance, as well as high tensile and yield strengths. The hardness after hardening is determined by the carbon content and the heat treatment parameters. It is used, among other things, for various types of cutting applications, such as knives and cutting tools, gardening tools, surgical instruments, and measuring tools. We supply martensitic steels in both the unhardened and hardened states, available on a made-to-order basis. Just as with hardened carbon steel, the formability of hardened stainless steel is severely limited. These steels are magnetic.
