Reliable supplier of EN steel grade S235J0 plates

SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, EN steel grade S235J0 plates with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, EN steel grade S235J0 plates seamless steel pipes for ships and petroleum cracking EN steel grade S235J0 plates steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many EN steel grade S235J0 plates products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Laser cutting, it is a specific way of cutting EN steel grade S235J0 plates steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting EN steel grade S235J0 plates speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In EN steel grade S235J0 plates, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

Both parties shall confirm the EN steel grade S235J0 plates material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the EN steel grade S235J0 plates steel plant.
