S690QL specification pdf Material Specification

EN10025-3 S460N high-strength steel has high strength, especially in normalizing or normalizing and tempering state. It has higher comprehensive mechanical properties. S460N plates are mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. S460N mechanical properties: tensile strength Rm500-680MPa, yield strength: 420-320MPa, elongation after fracture 18-19%.

Weather-resistant steel plate has excellent hot-rolled steel plate with resistance to sulfuric acid dew point corrosion. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials S690QL specification pdf that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance and is in line with today's high efficiency, long life and energy saving.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S690QL specification pdf steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
