ASTM a992 steel EN 10025-6 grade S690QL is recognized as the most suitable steel for wide flange beam in the world. It contains a variety of alloy elements, such as vanadium, niobium, copper, nickel, chromium and molybdenum, which greatly improve EN 10025-6 grade S690QL its strength and other properties. For example, the mechanical properties are much better than the tensile strength 65ksi and yield strength 65ksi of a572-50 and A36. Therefore, a992 wide flange beam (H beam) generally replaces a572-50.

Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate EN 10025-6 grade S690QL should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.

Try to use EN 10025-6 grade S690QL high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the EN 10025-6 grade S690QL temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

EN 10025-6 grade S690QL, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.
