0,00%K41 – 1.4509
K41 – 1.4509
Our KARA range. A 17% chromium Ferritic Stainless Steel stabilised with titanium and niobium.
Main features
Good weldability; ease of forming; suitable for surface finishing (polishing, brushing, scotch bright); good resistance to corrosion (in boiler and gas environments), pitting corrosion, and high temperature oxidation (up to 950°C); enhanced hot mechanical properties (without risk of σ phase formation at intermediate temperatures); greater thermal conductivity and lower expansion coefficient than austenitic grades.
Applications
- Catering kitchen cladding, trolleys, work surfaces
- Extractor hoods, hobs, oven casings and linings
- Sinks
