UGIMA® 4541 Annealed
UGIMA® 4541 Annealed introduction
The main property of UGIMA® 4541 is its resistance to intergranular corrosion. It uses titanium as a stabilising element to avoid the formation of chromium carbides in the grade when it is used at high temperature.
The mechanical properties of this stainless steel are better than those of 1.4307.
UGIMA® 4541 is specifically designed for machining and bar turning and provides increased productivity for these operations.
UGIMA® 4541 has excellent oxidation and corrosion resistance and good creep behaviour. It is particularly recommended for applications requiring heat resistance at continuous or cyclic operating temperatures (400 – 850°C).
Equivalent material: DIN 1.4541, DIN X6CrNiTi18-10, UNS S32100, AISI 321, JIS SUS321, ISO 4541-321-00-I, ISO X6CrNiTi18-10, EN 1.4541, EN X6CrNiTi18-10
