Carbon steel flange refers to a flange or end flange connector made of carbon steel as the main body material. The flange containing carbon steel material is called a carbon steel flange. Common materials include cast carbon steel grade WCB, forgings A105, or Q235B, A3, 10 #, # 20 steel, 16 manganese, 45 # steel Q345B, etc.
Usually, to prevent rusting, the surface of the flange is coated with electroplated coatings (yellow zinc, white zinc, etc.), or treated with anti rust oil and spray anti rust paint.
