Exceptional corrosion resistance for very high or very low application temperatures
Resistance to corrosion, for low and high temperature applications with excellent machinability - BGH austenitic steels are very versatile.
With our precise heat treatment, we create a precipitation-free and homogeneous microstructure, the basis for reliable workability and optimal operating properties, e.g. as an efficiently machinable material for shafts in kitchen machines or as a temperature-resistant wire conveyor belt in industrial continuous furnaces. In medical technology, BGH austenitic grades are used for components for asthma inhalers, among other things.

Properties
1.4305 is an austenitic Cr-Ni steel with added sulfur for optimal machinability (free-cutting steel).
Due to the sulfur addition, corrosion resistance in acidic and chloride-containing media is limited; however, the steel is resistant to steam up to 400 °C.
Due to its susceptibility to hot cracking, 1.4305 should not be welded.
Delivery Condition
- solution annealed (+AT) max. 230 HBW
Application Area
Machined components for use in mildly to moderately corrosive environments.
Typical Applications
- Automotive industry
- Valves and fittings
- Mechanical and plant engineering
- Decorative elements

Properties
1.4310 is an austenitic Cr-Ni steel with good corrosion resistance (PREN ≈ 18). The formation of chromium-depleted areas as a result of additional heat treatment beyond the as-supplied condition creates a risk of intergranular corrosion.
Polishing the surface achieves the best possible corrosion resistance.
During cold forming, the material work-hardens through the transformation of metastable austenite into martensite; this reduces its resistance to corrosion.
Delivery Condition
- solution annealed (+AT)
Application Area
Used in the cold-formed state in spring components with operating temperatures of up to 300 °C.
Typical Applications
- Spring components
- Clamping springs (electrical industry)
- Food industry
- Stamped and deep-drawn parts
