When standard stainless steel such as 1.4401 reaches its limits, it is advisable to use duplex stainless steel. The high-quality stainless steel with the designation 1.4462 offers excellent corrosion resistance and is ideal for chloride-containing, acidic, and alkaline environments. We offer duplex stainless steel cables in the proven 7\u00d77 construction and optionally with end fastenings and coating.<\/p>\n<\/div>
Properties:<\/strong><\/span> Duplex stainless steel 1.4462 can be used at temperatures ranging from \u2013100\u00b0C to +250\u00b0C, is slightly magnetic, and offers impressive strength and resilience. At the same time, it provides excellent corrosion resistance and mechanical properties, ensuring that it remains reliable even under dynamic stress and in aggressive environments.<\/p>\n<\/div><\/div><\/div>Application<\/strong>:<\/span> The material is particularly suitable for applications requiring a high level of corrosion resistance. It is used reliably in industry and construction as well as in offshore and maritime applications.<\/p>\n<\/div><\/div><\/div>Surface<\/strong>:<\/span> As with conventional stainless steel cables, the surface of the duplex stainless steel cables is high quality and can be provided with an additional protective coating if required.
