TC128 Steel Plate
TC128 steel is a high-strength, low-alloy steel designed specifically for applications that require high toughness at low temperatures. It is commonly used for energy-industry components—particularly in pressure vessels and components for nuclear plants and other critical applications.
TC128 is a low-alloy structural steel that provides excellent toughness, tensile strength, and resistance to deformation—even at extremely low temperatures. It is well-suited for equipment operating in severe conditions, including oil and gas processing, pressure vessel construction, and other critical structures requiring high impact resistance.
- High low-temperature strength: Ideal for cold environments without loss of mechanical properties.
- Excellent toughness: Resists fracture and impact in extreme conditions.
- Good weldability: Suitable for welded fabrication, enabling complex components.
- Impact resistance: Ideal where shock and fracture resistance are critical.
- Versatility: Used in energy, nuclear, petrochemical, and heavy machinery applications.
- Energy industry: Pressure vessels, nuclear equipment, and power plant components.
- Petrochemical industry: Gas and oil processing plant components, especially under extreme pressure and temperature conditions.
- Construction: Metal structures subjected to high stress and low temperatures.
- Heavy machinery: Structural components operating in severe environments.
