EN 10025-6 grade S690QL plates Pressure Vessel Quality, PVQ Plate

50Mn2 seamless steel pipe is a kind of high-strength medium-carbon quenched and tempered manganese steel. It has high strength, elasticity and wear resistance. At the same time, EN 10025-6 grade S690QL plates product has high hardenability. The critical hardenable diameter in oil is 10-28mm. The critical hardening diameter is 24～49mm, and the machinability is fair.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, EN 10025-6 grade S690QL plates weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

The hot rolling method is to heat the EN 10025-6 grade S690QL plates steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of EN 10025-6 grade S690QL plates rolling process is usually called semi-finished product production, also called blank production.
