Excellent toughness, even at low temperatures
Corrosion resistance
The material 2.4360 is insensitive to chloride-induced stress corrosion cracking and is characterised by excellent resistance to neutral and alkaline salts. Alloy 400 is one of the few materials that can be used in contact with fluorine, hydrofluoric acid and hydrogen fluoride or their compounds. Furthermore, this material is highly resistant to highly diluted mineral acids (sulphuric and hydrochloric acid), provided they are not aerated, as well as alkaline media and seawater.

Weldability
The material 2.4360 is easy to weld using conventional welding processes. These include TIG, TIG hot wire, plasma, MIG/MAG and SAW. The workpiece should be welded in a soft-annealed and dirt-free condition. Low heat input and targeted heat conduction are recommended. The line bead technique should be used. The temperature of the intermediate layers should not exceed 150°C. Annealing colours should be removed directly after welding, i.e. while still warm, using a stainless steel brush.
Machinability
Alloy 400 has good machining properties compared to other nickel alloys. Work-hardened, stress-relieved annealed material favours the machining process. However, due to the tendency to work hardening, a low cutting speed and a low feed rate should be selected. The tool should be in constant engagement. A sufficient cutting depth should be selected so that the previously created work-hardened zone can be undercut. To ensure a stable cutting process, heat dissipation should be optimised by using large quantities of suitable, water-based cooling lubricants.
Cold forming
The material 2.4360 can be cold formed very well. Although this material tends to increase work hardening, this also increases the strength. However, a final stress-relief heat treatment should be carried out. Intermediate annealing should be carried out for heavy cold forming.
