1.3952, 1.4910, 1.4429 – High-alloy steel

1.3952, 1.4910, 1.4429 – high-alloy steel grades also known under the AISI single standard designation as 316LN. They are characterised by very high corrosion resistance. These materials are known for their excellent properties and wide range of applications in various industries. The materials contain high levels of chromium and nickel to ensure their corrosion resistance. In addition, they are alloyed with molybdenum, which increases the resistance to various local corrosion types such as pitting and crevice corrosion. Another alloying element is nitrogen, which increases strength and resistance to corrosion cracking. A low carbon content (abbreviated to L) minimises the risk of intergranular corrosion after welding.

Peeled, polished round bars in diameters of 16, 25, 32, 40, 45 mm, tolerance h11 on stock. Other dimensions on request.
