What is 09MnNiDR steel plate

Introduction of 09MnNiDR steel plate:
09MnNiDR steel plate is steel for low temperature pressure vessel. It is used for manufacturing pressure equipment and structures used below - 20℃. Low alloy steel plate for low temperature pressure vessel has good comprehensive mechanical properties, cold bending and welding properties. It is necessary to ensure not only the strength, plasticity and toughness requirements under working conditions (temperature and pressure), but also the good processing performance in the process of vessel manufacturing. According to different temperature, low-temperature pressure vessel steel mainly includes low-alloy high strength steel, nickel steel and austenitic stainless steel.

09MnNiDR steel plate executive standard: GB3531.

Delivery status of 09MnNiDR steel plate: normalizing or normalizing + tempering, quenching + tempering, - 70℃ low temperature impact.

The package, mark and quality certificate of 09MnNiDR steel plate shall comply with standard GB / T247.
