Equivalent Materials for Different Steel Products according to DIN/EN and ASTM/ASME


Manufacturing internationally can be difficult. Not only the language barrier can cause confusion. Also, common material standards often vary from country to country. While it is still possible to produce the same quality with materials following a different standard it is still necessary to use the right equivalent materials. Especially for steel materials, it is important to use the right equivalent material for DIN/EN and ASTM/ASME pipes, tubes, plates, sheets, round bars, flanges, fittings and so on.

On this page, we have listed the most common materials for which we often need the equivalent material. These are all materials with which we produce our heat exchangers, thermal oil heaters, boilers, piping systems, skid installations and more.

Sheet / Plates S235J2 A36
P355GH A516 Gr. 70
Round Bars C45E S45C
Flanges C22.8 A105
Fittings P265GH A234 WPB
