1.4548 (WL 1.4548 : 1989-01)	X5CrNiCuNb17-4-4	1.4548	WL 1.4548 : 1989-01	Valid	Germany	1.1.2	1)
1) Remark: The hardenable stainless chrome-nickel-copper-steel 1.4548 which is permitted for aviation and aerospace is low-distortion, weldable and decarburization-proof. It shows in hardened condition a wide high strength range. Conditions .5 and .6 should be avoided for risk of stress corrosion. The material is cold formable at lower cross-sections in condition .9. Metal-cutting cold forming is more difficult than at usual construction steels. Attention should be paid to appropriate cutting tools and cutting conditions, sufficient cooling and sharp cutting edges. The material is suitable for arc-inert gas shielded welding. It is being welded generally in condition .3 and .4. After welding should be again hardened or precipitated. Application of 1.4548 for components showing high strength and high corrosion resistance at temperatures up to 300 °C. after single heat treatment.
