Stainless steel electrode using the Note
2012-06-01 by seoer8
A chromium stainless steel with corrosion (oxidation acid, organic acids, cavitation), heat and abrasion resistance. Typically used in power plants, chemical, oil and other equipment and materials. Chromium stainless steelWelding Electrodepoor, should pay attention to the welding process, heat treatment conditions and selection of suitable welding.
2, chrome 13 stainless steel welding, hardening of large, prone to crack. The use of the same type of chromium stainless steel electrode (G202, G207) welding, preheat and post weld more than 300 ℃, 700 ℃ about slow cooling processing. Weldment can not weld heat treatment, you should make use of chrome-nickel stainless steel electrode (A107, A207).
3 17 stainless steel, chrome, to improve corrosion resistance and weldability appropriate increase in the amount of stability elements of Ti, Nb, Mo, welding better than the chrome 13 stainless steel. Using the same type of chromium stainless steel electrode (G302, G307) should be carried out more than 200 ℃ preheat and post weld tempering around 800 ℃. Weldment can not be heat treated, you should make use of chrome-nickel stainless steel electrode (A107, A207).
By repeated heating, chrome-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical equipment manufacturing, chrome-nickel stainless steel welded carbide precipitation and reduce the corrosion resistance and mechanical properties .
6, drug skin of chrome-nickel stainless steel with titanium calcium type and low-hydrogen type. Titanium calcium type can be used for AC-DC, AC Welding Supplies penetration is shallow, and easy to redness, so as far as possible with DC power supply. Diameter of 4.0 and below can be used for all position welding of 5.0 and above for flat butt and fillet weld.
