X5CrNiMoTi15-2 Ferritic Stainless Steel Introduction
X5CrNiMoTi15-2 (material number 1.4589) is a ferritic stainless steel specified in EN 10088-1. It contains chromium, nickel, molybdenum, and titanium, which provide improved corrosion resistance, particularly against stress corrosion cracking, and good weldability. The titanium addition stabilizes the structure and prevents intergranular corrosion. This grade is typically supplied in the annealed condition and is used in moderately corrosive environments, such as automotive exhaust systems, chemical equipment, and architectural components where a combination of strength, corrosion resistance, and cost-effectiveness is required. It offers good formability and can be readily welded.
X5CrNiMoTi15-2 Ferritic Stainless Steel Chemical Composition
The chemical composition conforms to EN 10088-1:2014 for grade X5CrNiMoTi15-2 (1.4589). Titanium content must be at least 7 times the sum of carbon and nitrogen content to ensure stabilization. All values are maximum unless a range is given.

Notes:
Welding consumables should be selected with matching composition (e.g., EN 1600 E 15 9 L or similar for dissimilar welding). The material is ferromagnetic. For applications requiring higher toughness at low temperatures, ferritic steels may not be suitable. Consult the standard for specific product forms and thickness ranges as mechanical properties may vary.
