ASME SA210 GR A1 Carbon Steel Seamless Tube For Boilers Application

ASME SA210 GR.A1 Carbon Steel Seamless Tube For Boilers Application

ASME SA210 GR.A1: This refers to a specific grade of carbon steel that meets the requirements of the American Society of Mechanical Engineers (ASME) for pressure vessel and boiler tubing. This alloy primarily consists of iron and carbon, with small amounts of other elements like manganese and silicon. For GR.A1, carbon content is generally around 0.25–0.35% with specific allowances for manganese, phosphorus, sulfur, and silicon.

It conforms to ASME SA210, which is designed for use in the production of carbon steel tubes for boilers and other high-temperature services.

The material is also subject to certain mechanical testing, including tensile, hardness, and impact tests, to ensure reliability under operational conditions.

Chemical Composition:

• Carbon (C): 0.25% to 0.35%
• Manganese (Mn): 0.30% to 0.60%
• Silicon (Si): 0.10% to 0.35%
• Phosphorus (P): ≤ 0.035%
• Sulfur (S): ≤ 0.035%

Mechanical Properties:

• Tensile Strength:Range: 415 - 550 MPa (60 - 80 ksi)
• Yield Strength (or Yield Point): Minimum: 240 MPa (35 ksi)
• Elongation:Minimum: 35% in 8 inches (200 mm) or 40% in 200 mm
• Hardness:Brinell Hardness: Maximum value of 160 HB
• Modulus of Elasticity:Range: Typically 200 GPa (29 × 10⁶ psi)

Applications:

Boilers: The tubes are widely used in the construction of heat exchangers and boilers for generating steam in power plants.

Pressure Vessels: Often found in pressure vessels where high-temperature resistance and strength are critical.

Heat Exchangers: These tubes are also used in the construction of heat exchangers for fluid heating or cooling.
