When it comes to Alloy Steel Grade 12 Coil, you’re looking at a material that’s mainly made up of chromium (0.80–1.25%) and molybdenum (0.44–0.65%), with just the right touch of carbon (≤0.05%), manganese, phosphorus, sulfur, and silicon. This alloy is known for its fantastic resistance to corrosion and oxidation, especially when the heat is on. In terms of mechanical properties, it boasts a tensile strength between 415 and 585 MPa, a yield strength of about 205 MPa, and an elongation of roughly 20%. Plus, it’s got good weldability, toughness, and can handle thermal fatigue, making it a go-to choice for tough applications that deal with high temperatures and pressure.
You’ll find Alloy Steel Grade 12 Coil widely used in industries that demand top-notch thermal and mechanical performance. It’s a staple in power generation, petrochemical, and chemical processing sectors, often used for making components like boilers, pressure vessels, superheaters, and heat exchangers. Its impressive resistance to scaling and creep makes it perfect for piping systems and structural parts that operate in high-temperature settings. On top of that, its durability and formability allow for efficient fabrication and a long service life, ensuring reliable performance in critical industrial operations.
