Baja X6CrNiNb18-10 (+AT) – Resistensi Korosi Superior & Keawetan Las (EN 10216-5)
Baja X6CrNiNb18-10 setara dengan X 6 CrNiNb 18 10 sesuai DIN 17440: 1985-07. Sifat korosinya setara dengan 1.4541. Baja ini tahan terhadap korosi interkristal juga dalam kondisi sensitif, namun menunjukkan kecenderungan pecah panas pada kondisi las tertentu.
Aplikasi luas untuk bagian las dalam rekayasa aparatur kimia, industri makanan dan mewah, industri film dan foto, serta peralatan rumah tangga. Baja ini tidak cocok untuk finishing permukaan cermin karena kandungan niobium (Nb)nya.
