06Ni7DR belongs to steel plate for low temperature pressure vessel.
The executive standard of 06Ni7DR is GB/T713.1-2023.
The usual delivery condition of 06Ni7DR is: normalized or normalized+tempered. If there is an agreement in the inquiry and order, it can also be delivered without heat treatment.2. 06Ni7DR is recommended to be normalized at a temperature of (890℃-950℃) in the heat treatment. And normalizing, when the entire cross-section to get the required temperature, there is no need to continue to hold and usually should be avoided.
European Standard EN10028-2:2003 High-temperature performance steel plates for the manufacture of vessel equipment. Tensile strength Rm360-630MPa, yield strength ReH: 235-355MPa, elongation small 20-24%, small impact KV J °C -20°C --27J, 0°C --34J, +20°C --40J: European Standard EN10028-2:2003 products up to a thickness of 8-260mm. condition: +N normalized, +NT normalized plus tempering, +QT quenching and tempering.
