DIN 17100 UST37-2 mild structure steel plates have good toughness and casting properties, and its elongation and strength are well guaranteed. Besides, UST37-2 steel are suitable for stamping and welding. With those strengths, DIN 17100 UST37-2 mild structure steel plates are widely used in building and bridge engineering for production of welding structures.

DIN 17100 UST37-2 mild structure steel plates are rimming steel. When rolling UST37-2 steel plates, it is permissible to exceed the maximum value indicated, provided a phosphorous content per 0.001% N of 0.005% P below the maximum value indicated is maintained.The nitrogen content may not,however,exceed a value of 0.0012% N in the ladle analysis and 0.0014% N in the sample analysis.
