Mechanical properties of boiler steel pressure vessel plate 16Mo3

16MO3 steel plate is a foreign brand steel plate, used to make boilers and pressure vessels. It is different from other raw materials during welding. It must be preheated first, and the welding seam should be kept for about 30 minutes after the welding is completed. 16MO3 manganese steel plate is also an important alloying element steel, it is an important hardenability element, it has a great influence on the patience of the weld metal. The 16Mo3 executive standard is: European standard EN10028-2.

Mechanical properties of 16Mo3 steel plate:

Yield strength R/MPa: ≥260

Tensile strength R/MPa: 440-490

Elongation after breaking (%): ≥22

Impact temperature (℃): 20

Impact energy small value (J): 31

Chemical composition of 16Mo3 steel plate

Grade C Si Mn P S Cu Ni Cr Ai N
16Mo3 steel plate 0.12-0.20 ≤0.35 0.40-0.90 ≤0.025 ≤0.01 ≤0.3 ≤0.3 ≤0.3 ≥0.02 ≤0.012

Features of 16Mo3 steel plate:

Heat resistance and corrosion resistance.

When the Mn content is less than 5%, the patience of the weld metal is very high;

When the Mn content is greater than 3%, then it is very brittle;

When the Mn content is between 60% and 180%, the weld metal has higher strength and resistance.
