EN steel grade S275J2 plates thickness with 12-50mm

ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the EN steel grade S275J2 plates mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.

After adding a small amount of niobium, vanadium and titanium to EN steel grade S275J2 plates etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

The quality of EN steel grade S275J2 plates shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of EN steel grade S275J2 plates buyer, such as packaging, delivery time, etc.. On the basis of the quality of EN steel grade S275J2 plates in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements.

The Metals Industry Organization last week discussed two things on the Article 232 of the U.S. Trade Expansion Act of 1962 “25% and 10% tariffs on imported EN steel grade S275J2 plates, steel and aluminum products, respectively”implemented in March 2018, and CBP - US Customs and Border Protection Administrative Office considered to delay the payment of import tariffs.
