DIN 2393 precision welded steel tubes undergo a variety of processing and heat treatment processes, such as internal and external burr removal, annealing and pickling, cold rolling, bright annealing, etc., to obtain the required dimensional accuracy and mechanical properties.
DIN 2393 specifies the marking method of steel tubes, which usually includes information such as material, delivery status, outer diameter, inner diameter, etc. For example, DIN 2393 – St 52-3 BK 18×ID 13, the material is St 52-3, the delivery status is BK (bright drawn), the outer diameter is 18mm, and the inner diameter is 13mm.
DIN 2393 precision steel tubes are widely used in the fields of automobiles, solar energy, metal products, structural pipe making, etc. due to their high precision and good mechanical properties.
