JIS SM490C plates Pressure Vessel Quality, PVQ Plate

JIS SM490C plates,15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of and 15CrMo alloy plate is obvious and the weldability is poor After welding, local high temperature tempering treatment should be carried out The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling,JIS SM490C plates.

JIS SM490C plates,09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel has a protective effect against corrosion.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
