State-of-the-art technologies in steel production and development as well as application-specific knowhow are the hallmarks of Deutsche Edelstahlwerke. One of the most challenging and functionally most important components in the shipbuilding industry is the boat shaft.
There is a high demand for high-quality, turned or precision-ground steel bars, especially in construction of passenger ships, yachts and tugboats.For reliable use in seawater, high corrosion resistance is essential.
To withstand the high processing loads during propulusion of the propeller, excellent toughness and strength are required. The special steels of the Deutsche Edelstahlwerke meet these requirements.
|Acidur 4301||1.4301 / 1.4307||304 / 304 L|
|Acidur 4404||1.4401 / 1.4404||316 / 316L|
|Acidur 4462||1.4462||F51 / F60|
Best straightness, is essential for a precise installation and perfect functionality of boat shafts. Due to the straightness of 2 mm/m to 0.5mm/m, Deutsche Edelstahlwerke is the technology-leading supplier for boat shafts. In a diameter range of 50 mm - 270 mm (2 inch - 11.4 inch), and lengths up to 26 m, bars with the best straightness are available.
|2 mm/m||standard, available in full dimension range|
|1 mm/m||straightened by reeling, available up to 130 mm|
|0.5 mm/m||straightened by high performance straightening press, available from 90 mm to 250 mm|
In addition to a wide range of dimensions and narrow tolerances in straightness, three different surface finishes are available.
|peeled||standard, available in full dimension range|
|polished||available up to 325 mm round|
|belt ground||available from 90 mm – 245 mm round|
