Description
12Cr1MoV Steel Plate Overview
12Cr1MoV plate is a low-alloy structural steel known for its strength and resilience in high-temperature environments. The alloy consists of elements such as Chromium, Molybdenum, and Vanadium, which contribute to its superior mechanical properties, making it ideal for high-pressure and high-temperature applications.
It is widely utilized in industries like petrochemical, power generation, and manufacturing of boilers and pressure vessels. Its excellent creep resistance, oxidation resistance, and ductility under stress make it suitable for these demanding applications.
Composition and Key Properties
- Chromium (Cr): Enhances oxidation resistance and high-temperature strength.
- Molybdenum (Mo): Increases toughness, creep resistance, and the ability to withstand thermal stress.
- Vanadium (V): Contributes to better ductility and stability at high temperatures.
Together, these elements give 12Cr1MoV steel excellent creep resistance, meaning it maintains its strength and structure under long-term exposure to high temperatures and stress.
12Cr1MoV Plate Features
- Oxidation Resistance: High resistance to oxidation makes it reliable for long-term use in high-temperature environments.
- High-Temperature Strength: Capable of enduring high pressure and stress at elevated temperatures, typically up to 580°C.
- Creep Resistance: Offers excellent resistance to creep, making it ideal for prolonged use under extreme conditions without significant deformation.
- Ductility: Exhibits good ductility under stress, which reduces the likelihood of material failure under prolonged use.
- Weldability: While the material has good weldability, it requires preheating to 300°C before welding and post-welding heat treatment to relieve stress.
- Machinability: The material is easy to machine but can be sensitive to cooling rates during normalizing.
Applications of 12Cr1MoV Steel Plate
The high-temperature resistance and strong mechanical properties of 12Cr1MoV make it suitable for various critical industrial applications, including:
- Boilers: Used in the construction of boiler components that must withstand high temperatures and pressures.
- Pressure Vessels: Fabrication of high-pressure vessels in industries like chemical processing and power generation.
- Power Plants: Essential in power plant elements that operate in extreme heat, such as turbines and heat exchangers.
- Pipelines: Suitable for high-pressure piping systems in environments with temperature fluctuations.
12Cr1MoV Boiler Steel Plate Features
- High Oxidation and Heat Strength: Essential for long-term reliability in high-temperature and high-pressure conditions.
- Ductility Under Pressure: Retains high ductility even under stress, ensuring safe operation under heavy loads.
- Preheating and Post-Welding Treatment: To achieve optimal welding results, preheating to 300°C and post-weld stress-relief are recommended for this material.
While 12Cr1MoV performs well at elevated temperatures, long-term use at 580°C may lead to pearlite spheroidisation, affecting the material’s microstructure and potentially reducing its strength.
