DIN 2393 Grade St 44-2 is a low carbon alloy steel, whose primary use is for structural purposes. It is generally used in conjunction with standard DIN 2393 to form different types of seamless and welded tubes. 

st44 steel equivalent EU S275JR, EN 1.0044, A283 Gr D, A529 Gr D, DIN RSt42-2 JIS SS400, AFNOR E28-2, EN Fe430B, UNI Fe430B, GB Q225A, GB Q275Z, SS 1411, SS 1412, NS12142, GOST St4ps, GOST St4sp, ISO E275B, IS2062.

DIN 2393 St 44-2 BK have a tighter tolerance and when used for any application, they are intended to have a snug fit. Hence, DIN 2393 st 44 2 bk is used to improve the functionality of the application.
DIN 2393 st 52.3 is used for Machinery parts, mobile equipment, crane, boom, chassis, buildings, bridges and most structural activities.

DIN 2393 st 52.3 nbk is a low alloy, high strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it provides good cold-forming properties. It can be supplied in normalized or control-rolled condition.

DIN 2393 st 34-2bk are used for thin-walled precision constructional elements with a good surface condition.
DIN 2393 St 44-2 Precision welded steel tube has a special technical characteristic which determine the range of applications. It utilized in different applications such as metal carpentry, automobile parts, structures, farming industry, gates & protections etc.
DIN 2393-2 Grade St 44-2 bright drawn Tubes are essentially black steel tube that has had further processing. It is processed further in cold reduction mills, where the material is cooled at room temperature followed by annealing or tempers rolling. This process will produce closer dimensional tolerances and a wider range of surface finishes.

DIN 2393 Welded Precision Steel Tubes is used for hydraulic system steel tube, auto and motorcycle shock absorber, electric industry, construction machinery, gas spring, heat exchanger and condenser.
DIN 2393 Grade St 44-2 is a kind of structure steel. Its mechanical properties are Yield strength more than 275MPa, tensile strength 430-560Mpa. It is mainly used for welding, riveting, and bolting purposes. Structural Steels like ST 44-2 are used in many applications which need a combination of good welding properties with guaranteed strengths. Hence it is used in varied industries including civil and industrial engineering.
DIN 2393 st37-2 bk is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235. Owing to its chemical content, it doesn't have corrosive resistance. Hence, pre-painting or hot-dip galvanized is often engaged to protecting it from corrosion.
