At Luke Steel, we take pride in supplying Alloy Steel Grade 11 Coils, made from top-notch chromium-molybdenum steel. These coils are known for their impressive strength, thermal resistance, and ability to fend off corrosion. They’re a go-to choice in industries that need materials tough enough to handle high temperatures and harsh conditions. With outstanding creep strength and oxidation resistance, Grade 11 coils shine in power plants, chemical processing, and steam generation systems. We ensure that every coil meets the highest industry standards, providing durable and reliable solutions for applications facing thermal cycling, high pressure, and intense mechanical stress.
Alloy Steel Grade 11 Coil is composed of about 1% chromium and 0.5% molybdenum, which gives it remarkable resistance to high temperatures and oxidation. These coils boast a tensile strength ranging from 620 to 760 MPa, a yield strength of 450 MPa, and an elongation of 20%. Designed to perform at temperatures up to 600°C, they maintain their structural integrity even under significant thermal and mechanical stress. The unique composition of this alloy enhances its resistance to thermal fatigue, creep, and oxidation, making it perfect for demanding applications in power generation, petrochemicals, and other high-performance industries.
