StE255 is mainly used to fabricate boiler and pressure vessel.
So ,same the other boiler and pressure vessel using steel plate, StE255 steel has the good grain and Mechanical properties.
DIN17102 StE255 steel yield strength is 470 MPa, StE355 tensile strength is from 560MPa. (different min strength point at the different thickness.)
More detailed information about DIN17102 StE255 steel as follows.

DIN 17102 WStE255 steel plate/sheet under DIN standard, we can regard WStE255 steel plate/sheet for boilers and Pressure Vessels steels.
DIN 17102 WStE255 steel plate/sheet is for boilers and Pressure Vessels steels,
DIN 17102 WStE255 is a normalized steel plate and sheet which is mainly used for building pressure vessels and boilers and pipes for hot liquid.
The followings are the chemical composition and the mechanical properties of DIN17102 WStE255 steel.
This standard DIN 17102 StE255/WStE255/TStE255/EStE255 applies to hot rolled products in the form of flats(plate, strip, wide, flats), sections and bars of weldable fine grain structural steels exhibiting.
Its minimum yield strength of 225 to 255 n/mm referred to the lowest thickness.
