EN 10025-6 S460QL1 high strength steel heavy plate boiler steel

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 10025-6 S460QL1 high strength steel 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 10025-6 S460QL1 high strength steel materials and specifications can be ordered in advance.

The company can provide the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, markings and quality certificates of high-quality carbon structural steel hot-rolled steel plates and strips. Carbon and alloy steel grades 15Cr, 20Cr, EN 10025-6 S460QL1 high strength steel, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMo, 15CrMo, 20CrMo, 25CrMo, 30CrMo, 35CrMo, 42CrMo, 50CrMo, 12CrMoV, 35CrMoV, 12Cr1MoV, 25Cr2Mo1V, 38CrMoA1, 40CrV, 50CrV , 15CrMn, 20CrMn.

The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate EN 10025-6 S460QL1 high strength steelis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

The purpose of EN 10025-6 S460QL1 high strength steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of EN 10025-6 S460QL1 high strength steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

EN 10025-6 S460QL1 high strength steel, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality EN 10025-6 S460QL1 high strength steel products and more satisfactory services.
