Description

1.4501 (X2CrNiMoCuWN25-7-4) is a grade of super-duplex based on 25% chromium, 7% nickel with an addition of tungsten which enhances the pitting index (PREN) even further above the 40 minimum and also contributes to alloy strength. This high resistance to pitting is combined with a high tensile strength and higher resistance to stress corrosion cracking at moderate temperatures to that of conventional austenitic stainless steels. A small addition of copper (lower than in S32550/AMAZON 256) enhances its general corrosion resistance. It shows the following features and properties:

Very high strength

Very high resistance to pitting

Very good corrosion resistance

High resistance to erosion and abrasion in flowing systems

High resistance to stress corrosion cracking, fatigue and erosion
