Pressure vessel steel plate 16mo3


Pressure vessel steel plate 16mo3 is under europen steel standard en10028-2 which is for boiler used steel.Steel grade 16Mo3 specified as Chrome molybdenum steel alloy for use in elevated working temperatures. In German standard,the steel sheet 15Mo3 is the best equivalent steel grade for 16Mo3 steel plate.For rolling such steel grade 16Mo3,our engineers suggest that the end users to accept at least A435/A435M ultrasonic test,and for A578/A578M ultrasonic test standard we also can offer when rolling,such as A578 Level A,A578 Level B,A578 Level C.

Machinability of this material is similar to that of mild steel.

Technical Requirements & Additional Services:

  • High tension test
  • Low temperature impacting test
  • Simulated post-welded heat treatment (PWHT)
  • Ultrasonic test under EN 10160,ASTM A435,A577,A578
  • Issued Orginal Mill test certificate under EN 10204 FORMAT 3.1/3.2
  • Shot blasting and Painting,Cutting and welding as per end user’s demands

EN 10028-2 is the European steel standard which includes chrome moly plate for pressure vessel purposes.
