15CrMoR steel plate is used for pressure vessel.  It is a kind of medium temperature hydrogen resistant steel, 15CrMoR is Chinese grade name, which is equivalent with EN10028-2 13CrMo4-5 alloy steel.

 

Chinese Name:  

15 CrMoR Steel Plate  

Main Application:

Pressure Vessel Building 

Heat Treatment:  

Normalizing and Tempering  

 

15 CrMoR Steel Plate  

"15" is 0.15% of the carbon content  

"Cr" is the composition contains a certain chemical element - chromium  

"Mo" is the composition contains a certain chemical element - molybdenum  

"R" is the first letter of the container  

15CrMoR, heat treatment is often adopted as normalizing and tempering  

When under the temperature of 550℃, 15CrMoR has high durable strength.
