If material 1.4529 is our “king” among the special materials, then material 1.4462 is hardly inferior and just one step below it. To stay with the visual language of chess, 1.4462 stainless steel could be considered the “queen” of our special materials due to its versatility. Another name for it is duplex steel or just 1.4462 Duplex. This special material is a stainless, austenitic-ferritic stainless steel. Ferritic stainless steels have a chromium content between 12% and 18% with a very low carbon content of less than 0.2%. The special material demonstrates high strength and good corrosion resistance due to this combination. It is classified in Corrosion Resistance Class (CRC) IV as a result and demonstrates good resistance to intergranular corrosion or pitting.
The combination of the properties of austenite and ferrites in a single material opens up a wide variety of applications. Our customers particularly like to take advantage of our large stock of 1.4462 threaded rods. We can also offer our customers a cutting service for 1.4462 threaded rods on request.
