    2Cr13 is a martensitic stainless steel, which is magnetic and has good hardness, and should be preheated for welding. The austenitic stainless steel electrode for welding with Q235 does not need to be preheated, and a smaller current is used for welding. 2Cr13 welding consumables can be selected:
    Choose G202 and G207 for atmospheric corrosion resistance, preheat at 150-300 degrees, and temper at 700-730 degrees after welding;
    2. Organic acid resistance and heat resistance: G211, need to be preheated at 150-300 degrees;
    3. Good plasticity: A102, A107, A202, A207, A302, A307, preheating for repair welding, preheating for thick and large pieces.

    2Cr13 scope of application
    2Cr13 stainless steel has high hardness and good corrosion resistance in the quenched state. Many of them are used to make knives. They are "cutting tool grade" martensitic steels, and are also used for surgical knives. Similar to Brinell's high-chromium steel, the earliest stainless steel, it is also used as steam turbine blades, etc., and has a wide range of applications.
    2Cr13 density is 7.75g/cm3
    2Cr13 quenching hardness: Generally, the quenching temperature of 2Cr13 is 980~1050℃. When quenching with 980℃ oil, the hardness is obviously lower than that of 1050℃ heating oil quenching. The hardness after 980℃ oil quenching is 45~50HRC, and the hardness after 1050℃ oil quenching is 45~50HRC. 2HRC higher. However, the microstructure obtained after quenching at 1050 °C is coarser and more brittle. It is recommended to use 1000 ℃ heating and quenching to obtain better structure and hardness.
