S355J2G3

S355J2G3 Grade Introduction:

these steel exhibits excellent corrosion resistance. This can be seen in a variety of severe environments. Both reducing and oxidizing environments are not an issue for these steels. They can even resist high levels of chemicals including the most harsh and toxic ones. Nitric, organic, inorganic, sulphuric, acetic, formic, chlorides, hydrochloric acid, and phosphoric acid show no impact on these steels due to their exceptional resisting abilities. Also, they are good to work in stress corrosion cracking, crevice, and pitting environments.
