Which prawns can help give an answer, all kinds of stainless steel electrode guarantee period is how long, this has specific standards can be found? Thank youThe best hope for friends to answer, you can attach the standard name.
Stainless steel welding rod shelf life, good preservation for two years, do not damp. Stainless steel electrode can be divided into chromium stainless steel electrode and chromium nickel stainless steel electrode, these two kinds of welding rod in accordance with national standards, according to the national standard GB/T983-1995 examination. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation erosion), heat resistance and corrosion resistance. It is usually chosen as power station, chemical, petroleum and other equipment materials. But chromium stainless steel generally weldability is poor, should pay attention to welding process, heat treatment conditions and choose the appropriate welding rod. Chromium nickel stainless steel electrode has good corrosion resistance and oxidation resistance. It is widely used in chemical, chemical fertilizer, petroleum and medical machinery manufacturing. In order to prevent intergranular corrosion due to heating, the welding current should not be too large, less than 20% of the carbon steel electrode, the arc should not be too long, the inter layer is cold, and the narrow welding bead is suitable.
Save good words is two years, do not damp, and if it is relatively high requirements, the use of baking, remove moisture.
