Technical information - stainless steel 926
- old-rolled, rust-resistant spring steel 926
- cold-rolled, rust-resistant strip steel 926 annealed
Basic information and applications 926
Due to the addition of 6.0 to 6.5% molybdenum and an increased nickel content of over 24%, this material is extremely corrosion-resistant and suitable for many applications in the food industry and environmental protection and partly suitable for use in medical technology. The material 926 is sea water resistant, even at elevated temperatures in heat exchangers and at elevated salt concentrations such as in desalination plants. Since this material is almost non-magnetizable even in the hard-rolled state, it can be used for components that are exposed to strong magnetic fields.
Further application examples:
- Components in phosphoric acid production
- Components for the bleaching stage in the pulp industry
- Pressure vessels in the temperature range from -196 to 400°; Celsius
- Tanks for storing and transporting aggressive chemical substances
- Building authority approval for components and fasteners in the indoor area of swimming pools (approved by the German Institute for Building Technology, September 1998)
The material 926 is not listed in DIN EN 10 151 as a spring material.

Surface: 2R, roughness Ra maximum 0.3 µm (imprint of the work roll)
Tensile strength: 650-900 N/mm²
Yield strength Rp0.2: at least 300 N/mm²
Tolerances:
Thickness tolerance: DIN EN 9445 Table 1
Width tolerance: according to DIN EN 9445
Straightness: normal
Flatness: Wave height max. 1.0 mm
Additional mechanical data:
The following values apply to the hard-rolled version: With good edge processing after cutting (e.g. vibratory grinding), the reverse bending strength is around 35% of the tensile strength, with bending perpendicular to the rolling direction.
Because the reverse bending strength depends on various factors such as environmental conditions and the nature of the edges, no values can be guaranteed. Depending on the stress, the maximum application temperature is between 120 and 250 °C (cf. DIN 17224 - spring band made of stainless steel). Please note that Young's modulus values decrease with increasing temperature.

Editing information 926
Punching: This material is easy to punch. In the annealed state, this material can even be deep-drawn due to the high proportion of nickel of over 24%.
Laser cutting: The material 926 can be laser cut very well.
Etching: The material 926 is very easy to etch.
Bending in the hard-rolled condition: Since the strength of the material is achieved through the cold deformation during rolling, the rolling direction has a major influence on the bending.
Bending transverse (perpendicular) to the rolling direction:
| F1250-1600 N/mm² | |
| Up to 0.25mm | 1.0 x t |
| 0.25 - 0.50mm | 1.0 x t |
| 0.50 - 075mm | 2.0 x t |
| 0.75 - 1.00mm | 2.5 x t |
t = tape thickness
Bend along (parallel) to the direction of rolling:
| F1250-1600 N/mm² | |
| Up to 0.25mm | 2.5 x t |
| 0.25 - 0.50mm | 3.0 x t |
| 0.50 - 0.75mm | 4.0 x t |
| 0.75 - 1.00mm | 5.0 x t |
t = tape thickness
Bending in the annealed condition: Due to the high nickel content of over 24%, the material 926 can be folded and deep-drawn very well in the annealed condition.
Surface grinding: The material 926 has a purely austenitic structure in both the annealed and hard-rolled condition and is therefore practically non-magnetic.
Welding: The material 926, like other austenitic stainless steels, is very easy to weld. The heat input in the hard-rolled state can lead to a vascular change at the weld seam, which reduces the strength there. Due to the very low carbon content of max. 0.02%, corrosion on the weld seam is not to be expected on the material side. The materials Alloy 59 (material number 2.4605) and Alloy 625 (material number 2.) are recommended as filler metals.
Chemical Resistance 926
The material 926 is not included in the Nirosta table for the chemical resistance of stainless steels (see www.nirosta.de/Publikationen). Due to a high molybdenum content of over 6% and an increased nitrogen content of over 0.15%, material 1.4529 has significantly better corrosion resistance than material 1.4539 (in a separate group in the Nirosta publication , with a PRE value of 37) and many other stainless steels. With a PRE value of 45, the material 926 is comparable to the material 1.4565S (the best possible material in the Nirosta publication). Please check there or by means of a test whether the material 926 is sufficiently resistant for your application. Nirosta is a registered trademark of ThyssenKrupp AG. If material 1.4529 is not sufficient, nickel alloys such as material Alloy 59 (material number 2.4605) or material Alloy 2120 (material number 2.4700) must be used.

Precision feeler gauge tape Precision tapes / backing foils made of carbon steel C100S - 1095 are used among others in mechanical engineering as underlay foils, for aligning workpieces in grinding machines or for setting and measuring gap dimensions. Properties material 1095 With a carbon content of over 1%, this material is very well suited for feeler gauges and underlay foils as well as for highly stressed springs, which are not subject to any corrosion requirements. Compared to the materials 1.1231 (C67S), 1.1248 (C75S) and 1.1269 (C85S), which have a lower carbon content, the material 1095 is also suitable for high mechanical loads and has a high fatigue strength. Technical information The thickness tolerance is defined according to DIN EN 9445 table 1 or T3. The material 1095 is magnetizable and can therefore be clamped on magnetic chucks of grinding machines. The structure of the strip is changed by the hardening process. This means that the rolling direction does not have to be taken into account when edging. Bending radius: at least 10 times the strip thickness. The unalloyed steels must be estimated from corrosion by an oil film. Tinning or galvanizing or painting these steels can withstand corrosion permanently. Further applications / properties: Wear strips Printing racks very easy to etch magnetizable

Precision feeler gauge tape Precision tapes or metal foils made of spring steel CrNi - hard steel - 301 are used inter alia. in mechanical engineering as underlay foils, for aligning workpieces in grinding machines, adjusting games (assembly of workpieces) or measuring gap dimensions. Properties material 301 With this material, high strength is achieved by cold rolling. Compared to material 301, a much higher tensile strength can be achieved. Therefore, the material is very well suited for stainless precision gauges and shims as well as for stainless springs and parts with higher strength. Due to the alloy with chrome and nickel, this spring steel has good corrosion resistance. Material 1.4404 should be used in a corrosive environment. If no special requirements are placed on corrosion, the material 1.1274 can also be used. Technical information The thickness tolerance is defined according to DIN EN 9445 table 1 or T3 (for strength class 15-1700 N / mm²). Like other austenitic stainless steels, this steel is very easy to weld. However, the heat input at the weld seam can lead to a structural change (which reduces the strength) and, among other things, local corrosion of the weld seam. With material 301, when bending or bending, make sure that the bends should always run across the rolling direction. When used as a flat spring, the rolling direction must also be observed. Further technical information on our cold-rolled spring steel 301 can be found in our data sheet. Further applications / properties: Welded endless belts conveyor belts very easy to etch weakly magnetizable good corrosion resistance
