st45 material is a kind of material used for boiler and pressure vessel steels. It is characterized by minimum yield strength of 220 – 295 MPa.
DIN 2391 ST45 Carbon Steel Pipes has good weldability so it is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids. Along with good welding it also has superior impact strength as well.
ST45 DIN 2391 Carbon Steel Seamless Pipes is used as construction element with special requirements in dimension accuracy, small wall thicknesses and good surface condition.
ST45 DIN 2391 Carbon Steel Welded Tubes are last longer and has high ductility. It is available in different finishes such as polished, annealed, pickles and bright annealed. It is highly thermally conductive and transfers heat faster than the austenitic steels.
Carbon Steel DIN 2391 ST45 Piping has noticeable features such as corrosion resistant, leak proof, dimensional accuracy, durable structure, smooth finish, high temperature & pressure enduring capacity.
