IS 2002 Grade 2 (Carbon-Manganese Steel for Boilers & Pressure Vessels) IS 2002 Grade 2 is a medium-strength carbon-manganese steel grade specified under the Indian Standard IS 2002, primarily used for the construction of pressure vessels, boilers, heat exchangers, and related equipment. Known for its higher tensile strength compared to Grade 1, this grade is typically supplied in a normalized condition, ensuring improved mechanical properties and resistance to thermal and pressure-induced stress. It is well-suited for use in elevated temperature environments, such as power plants, refineries, and chemical processing units, where consistent performance and material integrity under pressure are essential. Key Features: Enhanced tensile strength compared to Grade 1 Good weldability and formability for vessel fabrication Delivered in normalized condition for structural stability Complies with IS standards for pressure-containing equipment Mechanical Properties: Property IS 2002 Grade 2 Yield Strength ≥ 240 MPa Tensile Strength 450–600 MPa Elongation ≥ 22% Temperature Resistance Suitable for up to ~400°C Weldability Very good Common Applications: Boilers, economizers, and superheaters Pressure vessels and storage tanks Reactors and heat exchanger components Drums and piping in thermal systems Power generation and chemical processing units Summary: IS 2002 Grade 2 offers a combination of higher strength, good weldability, and thermal endurance, making it a trusted choice for critical pressure-bearing equipment in various industrial sectors. It is ideal for use in equipment that demands safe operation under sustained pressure and temperature conditions.
