15Mo3 heat resistant steel plate for boiler and pressure vessel executive standard: DIN1715515Mo3 heat resistant steel plate delivery status: normally delivered in normalized status. According to the special agreement at the time of ordering, 15Mo3 heat resistant steel plate also be delivered in non processed status.15Mo3 heat resistant steel plate is mainly used for steam boiler equipment, ASTM A514 alloy steel plate, pressure vessels, large pressure pipes, drum manufacturing of utility boilers and similar components.
After quenching and tempering, 40Cr alloy steel plate and ASTM A514 alloy steel plate sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel ASTM A514 alloy steel plate is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
S355J2 steel plate ASTM A514 alloy steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the ASTM A514 alloy steel plate single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
