15CrMoR Pressure Vessel Steel Plate- SCALE STEEL.

15CrMoR steel plate is used for pressure vessel.  It is a kind of medium temperature hydrogen resistant steel, 15CrMoR is Chinese grade name, [SCALE STEEL]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 [SCALE STEEL]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.
