Requirements for chemical composition of EN steel grade S235J0 plates

Specification range of available steel EN steel grade S235J0 plates: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates EN steel grade S235J0 plates can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

In 2010, the 87th session of the International Maritime Organization (IMO) Maritime Committee passed the "Performance Standards for Alternative Anticorrosion Measures for Crude Oil Cargo Tanks". It is mandatory that the cargo tanks of large oil tankers above 5,000 dwt need to be protected or used The construction of corrosion-resistant steel promotes the rapid development of the research and application of corrosion-resistant steel for oil tankers in China. At present, the performance of domestic corrosion-resistant steel has reached the world's leading level and can meet the requirements of large-scale applications.

A572 grade can be divided into five levels: EN steel grade S235J0 plates, A572 grade 42 (290), 50 (345), 55 (380) for riveted, bolted or welded structural parts; A572 grade 60 (415) and 65 (450) for bridge riveted and bolted structural parts or welded structural parts for other purposes. Chemical composition of A572 Gr50 steel: C: ≤ 0.20, Si: ≤ 0.40, Mn: ≤ 1.50, P: ≤ 0.04, S: ≤ 0.05, Nb: ≤ 0.005-0.05.
