In terms of service, our service is a "one-stop" way of working. We have our own EN10025-4 steel plate processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as EN10025-4 steel plate cutting, welding, drilling, galvanizing, etc., at the lowest cost.

ASTM 36 is the most common alloy steel. It is used for most building components, including columns, beams, decorations, and completion elements. ASTM A36 EN10025-4 steel plate ductility does not allow the alloy to be used as a cable or as reinforcement (reinforcement). However, ASTM A36 is also perfect for most other purposes.

What are the characteristics of medium and thick plate, EN10025-4 steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, EN10025-4 steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used EN10025-4 steel plate, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

EN10025-4 steel plate, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of EN10025-4 steel plate and No. 20 steel is 7.85kg/cm3

The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think! Our quality is better for the EN10025-4 steel plate same products, our price is lower for the same quality, and our service is better for the same price. welcome to purchase steel materials from our company. we have the professional team and good after-sale system to customers. our company EN10025-4 steel plate is your best choose.
