What is 07Cr2AlMoR vessel plate

07Cr2AlMoR is one of the newly added grades in GB / T713 standard. The thickness range of 07Cr2AlMoR vessel plate is generally 6-60mm. 07Cr2AlMoR plate delivery status: normalizing and tempering. 07Cr2AlMoR steel is smelted by oxygen converter or electric furnace, and should be refined outside the furnace.

Chemical composition of 07Cr2AlMoR vessel plate (%):
C: Less than or equal to 0.09, Si: 0.20-0.50, Mn: 0.40-0.90, P: less than or equal to 0.020, S: Less than or equal to 0.010, Cr: 2.00-2.40, Ni: less than or equal to 0.30, Cu: less than or equal to 0.30, Mo: 0.30-0.50, Alt: 0.30-0.50.
Remarks: according to the requirements of the demander, appropriate amount of rare earth elements can be added to 07Cr2AlMoR steel plate.

07Cr2AlMoR vessel plate mechanical properties:
For thickness 6-36mm, the yield strength is greater than or equal to 260Mpa, the tensile strength is 420-580Mpa, the elongation is not less than 21%, and the V-type impact energy at 20℃ is not less than 47J. Thickness > 36-60mm, yield strength ≥ 250Mpa, tensile strength 410-570Mpa, elongation not less than 21%, 20℃ V-impact energy not less than 47J.

07Cr2AlMoR vessel plate is mainly used for manufacturing spherical storage tanks, and can also be used for manufacturing single-layer welding vessel, multi-layer hot sleeve welding vessel, multi-layer binding vessel and low temperature pressure vessel.
