1. Not stainless steel. 2. Because 35CrMo is an alloy steel, the main components are carbon, chromium, molybdenum and manganese and other elements, with high strength and hardness, suitable for the manufacture of high strength and high hardness parts. But it does not contain enough chromium to form the passivation layer required for stainless steel, so it does not belong to the category of stainless steel. 3. If you need to use stainless steel materials, you can choose other materials that contain enough chromium elements, such as 304 stainless steel or 316 stainless steel, which have good corrosion resistance.
