DIN 2391 ST52 carbon steel pipe is an easy to weld low carbon manganese steel pipe carbon content of 0.24%, silicon content of 0.55%, manganese content of up to 1.60%, with good impact resistance and physical properties of its tensile strength of not less than 490MPa, yield point of not less than 345MPa, elongation of not less than 22%.DIN 2391 ST52 seamless pipe is usually supplied untreated or standardised. or supplied under standardised conditions, with workability similar to that of mild steel.
DIN 2391 ST52 Seamless Precision Steel Tube has high tensile strength, structural rigidity, toughness, flexibility, corrosion resistance, durability, ease of use, long life and high temperature resistance. It is also resistant to stress corrosion cracking, pitting, crevice corrosion, oxidation and general corrosion resistance, properties that enable DIN 2391 ST52 steel tubes to maintain stable performance in a variety of extreme environments.
Therefore, DIN 2391 ST52 mild steel pipe is widely used in bridge structure, marine structure, engineering construction, oil and gas industry.
