Characteristics and application scope of ASTM A572 ms steel coil, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.
The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, ASTM A572 ms steel coil, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the ASTM A572 ms steel coil metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between ASTM A572 ms steel coil strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
