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.

16MnDR
16MnDR is a kind of low temperature pressure vessel steel plate. 16Mn- means that the carbon content in the steel plate is about 0.16%,D- means low temperature, and R- means pressure vessel (Usually, when the content of some chemical elements in steel is higher, it needs to be marked in the material, such as 1.6% manganese is written as 16Mn,16MnDR is used for -40 degrees pressure vessel steel plate 16MnDR delivery state normalizing level three or above defect detection.

10CrMo9-10
1.10CrMO9-10 is an alloy special steel with high temperature performance, implementation standard :EN10028-2, number: 1. 7380, used for manufacturing reactor heat exchanger separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor, pressure completion, liquefied petroleum steam hall, turbine volute.
2.10CRMO9-10 steel plate is high temperature and high pressure vessel steel plate, often used in power station boiler drum drum steam boiler equipment pressure vessel large pressure pipe and other equipment manufacturing and components 10 in 10CrMO9-10 grade represents the carbon content.
3.10CRMO9-10 Delivery status: the delivery status is normalizing and tempering (N+T) or tempering (Q+T), different delivery status can be selected according to the demand, or additional inspection standard requirements, inspection grade requirements, Z, performance requirements, special alloy elements, classification society certification requirements, etc.
4.10CrMO9-10 steel plate is usually delivered in normalizing and tempering state with thickness below 60mm, normalizing and tempering or tempering state with thickness greater than 60mm to 100mm, and tempering and tempering state with thickness greater than 100mm to 250mm can be delivered without processing state according to negotiation between the supply and demand parties.
