What are the top 5 EN steel grade S275J2 plates mills in Iran

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of EN steel grade S275J2 plates steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special EN steel grade S275J2 plates materials and specifications can be ordered in advance.

The company produces and export steel plates and steel section products of various materials all year round. The width of the EN steel grade S275J2 plates thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel EN steel grade S275J2 plates is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The EN steel grade S275J2 plates, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. EN steel grade S275J2 plates, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
