Grade Introduction:

We manufacture these using S355J2G3. This structural steel is non-alloy steel. EN 10025:1990 is the steel standard. The current standard for these steel is EN 10025-2:2004. These are thus tested at minus 20 centigrade to test its impact resistance. This universal corrosion resistance material is a widely popular grade for manufacturing.

Our steel thus 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.
