It is necessary to conduct preheating above 300 ℃ and slow cooling at about 700 ℃ after welding. If the weldment cannot be subject to Caron Steel Welding Neck Flanges post weld heat treatment, the welding rod for flange fittings (aa207) shall be selected. In order to improve the corrosion resistance and weldability of flange, appropriate stability elements such as Ti, Nb and Mo are added, and the weldability is better than that of chromium Caron Steel Welding Neck Flanges.
When the same type of chromium Caron Steel Welding Neck Flanges welding rod (gg307) is selected, it shall be preheated above 200 ℃ and tempered at about 800 ℃ after welding. If the weldment cannot be heat treated, the welding rod for flange fittings (aa207) shall be selected.
Flange elbow fittings and welding rods for Caron Steel Welding Neck Flanges have good corrosion resistance and oxidation resistance, and are widely used in chemical industry, chemical fertilizer, petroleum and machinery manufacturing.
