Technical properties:
1. High temperature resistance: The 10CrMo910 steel grade is designed to withstand high temperatures, making it suitable for applications such as power plant boilers and heat exchangers.
2. Corrosion resistance: The steel grade has excellent corrosion resistance, which is crucial in environments where chemicals or corrosive substances are present.
3. Weldability: It exhibits good weldability, allowing for easy fabrication and joining of structural components.
Chemical composition:
The chemical composition of the 10CrMo910 steel grade is as follows:
– Carbon (C): 0.08-0.15%
– Silicon (Si): 0.25-0.35%
– Manganese (Mn): 0.30-0.70%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.025% max
– Chromium (Cr): 2.00-2.50%
– Molybdenum (Mo): 0.90-1.10%
– Nickel (Ni): 0.30% max
These chemical elements enhance the steel’s mechanical and technical properties, such as its high temperature and corrosion resistance, by forming various phases and strengthening mechanisms within the steel’s microstructure.
