HastelloyC technical specifications

HastelloyC a high temperature, corrosion-resistant alloy

HastelloyC alloy contains a large number of Cr, Mo and other elements, and has single-phase austenite.

Has many excellent properties of corrosion resistant alloys, on the oxidation and reduction of medium has good resistance to corrosion.

Excellent resistance to stress corrosion cracking resistance capacity and good capacity of local clothing in many chemical process medium is satisfactory corrosion properties, including the erosion of a strong inorganic acid, chlorine, and various media containing chloride, dry chlorine, formic acid and acetic acid, water and salt water, etc..

HastelloyC corrosion resistance

1. At 70 ¡æ any of the following concentrations of sulfuric acid solution are corrosion-resistant, corrosion rate of about 0.1mm / a;

2. Various concentrations of hydrochloric acid at room temperature not higher than the corrosion rate of 0.1mm / a; at 65 ¡æ under various concentrations of hydrochloric acid was also less than 0.5 mm / a, hydrochloric acid is oxygenated, on the corrosion resistance showed a significant impact;

3. In hydrofluoric acid in the corrosion rate of less than 0.25 mm / a, the boiling temperature of 55% H3PO4 +0.8% HF conditions, the corrosion rate of the government more than 0.75 mm / a;

4. At room temperature or higher temperature for all concentrations of dilute nitric acid are corrosion, the corrosion rate of 0.1mm / a at about 60-70 ¡æ and under any of the concentration of organic acids and other chromic acid mixture are good corrosion resistance, corrosion rates were less than 0.125 mm / a and 0.175 mm / a;

5. Is a small capability of dry and wet corrosion of the material for chlorine can dry and wet chlorine gas exchange corrosive conditions;

6. To high temperature corrosion of HF gas at 550 ¡æ under HF gas corrosion rate of 0.04 mm / a, at 750 ¡æ, the corrosion rate of 0.16 mm / a.

HastelloyC processing

Thermal processing

1. Hot working temperature range of 1200 ¡æ ~ 950 ¡æ, cooling or rapid air cooling for the water.

2. To ensure the best corrosion resistance, thermal processing should be carried out after the heat treatment, has been heating up the workpiece should be added directly

Heat treatment furnace.

Cold

1. Hardening rate than austenitic stainless steel, requiring the selection of processing equipment. Workpiece should be solution heat treatment state, and due process in the cold intermediate annealing.

2. If the cold rolling is greater than 15%, you need to carry out the second solution treatment on the workpiece.

HastelloyC welding

Suitable for any conventional welding process welding, such as tungsten inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas welding, metal inert gas welding
