A chromium stainless steel with corrosion (oxidizing acids, organic acids, cavitation), heat-resistant and wear-resistant function. Typically used in power plants, chemical, oil and other equipment and materials. The welding of chromium stainless steel is poor, should pay attention to the welding process, heat the premise and the selection of suitable welding.

2, chrome 13 stainless steel welding, hardening of large, easily cracks. The use of the same type of chromium stainless steel electrode (G202, G207) welding, necessary to carry out about 700 ℃ preheat and post weld slow cooling processing more than 300 ℃. 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 the corrosion function and welding appropriate increase in the right amount of chaos 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).

4, chrome-nickel stainless steel electrode has good resistance to corrosion and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.

5, the chrome-nickel stainless steel welded carbide precipitation by repeated heating and reduce the corrosion resistance and mechanical function.

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 penetration is shallow, while easily 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.

7, the electrode should be used to keep dry, lime-titania type shall be approved by the dry one hour of 150 ° C, low hydrogen type should be dried by 200-250 ° C 1 hour (can not be repeated drying, or medicine skin cracks easily peel off) to prevent the  Welding Electrode drug skin sticky oil and other dirt, so as to avoid causing the weld to increase the carbon content and impact of welding quality.

8, in order to prevent the heating eyes erosion, welding current is not too large, about 20% less than the Carbon Steel Electrode , the arc should not be too long, rapid cooling layer, a narrow welding Road is appropriate.
