S355N steel plate application:
S355N steel plate is especially intended for use in heavily loaded parts of welded structures such as bridges, flood gates, storages tanks, water supply tanks ect, for service at ambient and low temperatures.
S355N steel plate also used to manufacture the plants of factory ,the common constructure and construction machinery and equipment; for example:Drilling machine ,Excavator,Tip lorry, Grab,Conweigh belt,Bulldozer ,all kinds of Chain Block, and other machiney equipments.
Katalor could provide S355N steel plate max thickness to 350mm . Max width 3800mm, we also could do the UT test, impact test, Chemical analysis, mechanical test, and Simulated may treatment according to our customer requirement.
