DIN17100 St50-2 steel plate applies to steel sections (including wide flange beams), steel bars,wire rod, flat products(strip, plate, wide flats) seamless and welded, square and rectangular hollow sections, forgings and semi-finished products in the general structural steels.
DIN 17100 St50-2 steel plate is similar with the steel grade S355J2 under steel standard EN 10025. Katalor rolling St50-2, the maximum thickness can reach till 400mm now, for the thickness above 40mm of low alloy steel plate St50-2, normally our engineers recommend doing Normalized heat treatment for plate steel St50-2. For the unit weight above 16 tons, steel mill would roll steel plate St50-2 from steel ingots for guarantee the steel property.Steel specification St50-2, Steel grade St50-2 and Grade steel plate St50-2.
