EN 10250-4 Grade X6CrAl13 soft annealed (+A)
EN 10250-4 Grade X6CrAl13 soft annealed (+A) introduction
The make X6CrAl13 is comparable to X 6 CrAl 13 acc. to DIN 17440 : 1985-07. Application predominantly in apparatus engineering of petroleum industry , e.g. for cracking facilities as well as for welded parts in hydroelectric power plant construction. Al-addition prevents hardness increase next to the weld seam and thus crack sensitivity. No resistance to intercrystalline corrosion in delivery condition as well as in welded condition.
