16Mo3
1.Standard :EN10028 EN10222-2 2017(European standard, foreign standard)
2.Naming: is based on the content of C(carbon) and Mo(molybdenum) to name, refers to the carbon content of the steel plate in about 160, and the content of molybdenum in about 300
3.heat treatment: normalizing or normalizing + tempering
16Mo3 steel plate Manganese is also an important alloy element in steel, but also an important element of hardenability, it has a great impact on the toughness of weld metal
16Mo3 steel plate when Mn content < The toughness of the weld metal is very high at 0.05%;
16Mo3 steel plate when Mn content > After 3%, it is very brittle; When Mn content = 0.6~1.8%,TEL:180~377~99127% Weld metal has higher strength and toughness. What is the effect of sulfur (S) element on weldability.
16MO3 steel plate? Sulfur often exists in the form of iron sulfide in steel and is distributed in a network at grain boundaries, which significantly reduces the eutectic temperature (985) of ductile iron and iron sulfide in steel. Therefore, during hot processing, the starting temperature of processing is generally 1150~1200 , and the iron and iron sulfide eutectic melting, already causing cracking when processing.
this phenomenon is called "sulfur brittleness" make this nature of sulfur steel produced during welding hot crack Therefore, generally in the sulfur content in the steel are strictly controlled ordinary carbon steel quality carbon steel and high quality steel main difference lies in how much sulfur phosphorus content Common specifications and dimensions.
15Mo3
15Mo3 Common implementation standards:
GB/T8162---- China national standard
GB5310
ASME SA210 ASME boiler and pressure vessel code
ASME SA213 ASME boiler and pressure vessel code
DIN17175 Federal German Industrial Standard
19Mn6
The German standard number of 19Mn6 high temperature structural steel is equivalent to national standard Q345R and European standard P355GH. 19Mn6 high temperature and high pressure boiler steel plate is mainly used for the production of power station boiler drum drum. It is produced according to the requirements of DIN17155 standard.
