DIN2440 St33.2 steel pipe is a medium-heavy threaded steel pipe or seamless steel pipe material produced in accordance with the German industrial standard DIN 2440.
The inner and outer surface quality of DIN2440 St33.2 carbon steel pipe has strict requirements and must be smooth and free of defects such as fins, pits, stratification, etc., and the wall thickness and outer diameter of the steel pipe must meet the specified allowable deviation.
DIN2440 St33.2 low-carbon steel pipe is used in some low-requirement mechanical processing, mechanical structural parts, building structures, and low-pressure transmission systems due to its good toughness and plasticity.
