タイトルまたは説明

Stellite is a kind of surfacing electrode with the welding core of casting alloy, which is  titanium calcium coating type. AC/DC, approprite DC reverse connection, and electrode to the positive. Arc stability, good slag coverage ang beautiful shape. Hardfacing layer has excellent comprehensive mechanical properties under **0 ºC high temperature range, and has good corrosion resistance, oxidation resistance, stained between metals resistence and wear resistence. Surfacing layer can be machined.
Usage: Used on the accasion requiring high temperature wear resistance and corrosion resistance, such as high temperature and high presure valve, valve, thermal cutting blade and hot forging die, etc.
Hardness of surfacing welding layer: HRC*8
License: XK***********0
Brand: Stellite
Note: 1. Electrode welding must be baked under the temperature around **0 ºC for 1 hour before welding; 
           2. Appropriate small current, short arc welding, to avoid increasing penetration of parent metal and reducing the performance of surfacing welding alloy;
           3. According to the types of parent material and size of workpiece, choosing ******0 ºC preheat temperature and **0 ºC interlayer temperature for surfacing welding;
           4. According to the working conditions, generally choosing ******0 ºC, heat preservation for 1 to 2 hours and then slow cooling furnace, or putting the workpiece under dry and hot sand cylinder or pulverin and then slowly cool.
