Product Description

ASME SA423 GR1 Carbon Steel Boiler Tube For Boilers , Steam Generators

ASME SA423 Gr. 1 is a carbon steel alloy, specifically formulated for high-pressure and temperature applications such as in steam boilers, heat exchangers, and other critical systems.

The material primarily consists of carbon, with trace elements like manganese, silicon, phosphorus, sulfur, and others, depending on the specific alloy grade.

This material conforms to the ASME SA423 specification, which defines the requirements for carbon steel tubes used in the construction of heat exchangers, superheaters, and other heat transfer equipment in power plants and industrial applications.

SA423 Gr. 1 carbon steel tubes typically exhibit good tensile strength, yield strength, and toughness at elevated temperatures.

The material is designed to withstand high-pressure conditions, with good resistance to internal and external stresses.

Chemical Composition:

Carbon: 0.18% - 0.23%
Manganese: 0.30% - 0.60%
Phosphorus: ≤ 0.035%
Sulfur: ≤ 0.035%
Silicon: 0.10–0.35%
Copper:≤ 0.25%
Chromium:≤ 0.20%
Nickel:≤ 0.20%

Mechanical Properties:

Tensile Strength: 415 - 550 MPa (60 - 80 ksi)
Yield Strength: 205 MPa (30 ksi) min.
Elongation: 30% min. (in 8 inches)
Hardness: 150 HB (Brinell Hardness) max.
Impact Toughness: Not typically specified, but the material is designed to withstand impacts at elevated temperatures.

Applications:

1. Boiler Systems

2. Heat Exchangers

3. Pressure Vessels

4. Power Plants

5. Chemical and Petrochemical Industries

6. Waste Heat Recovery Systems

7. Marine and Shipbuilding

8. Industrial Heating Equipment

With our humidity and year-round high temps, corrosion resistance and heat transfer are always a concern. These tubes have been performing nicely.

It's hot and humid here, and our old wrap-on tubes used to rust like crazy. Switched to your extruded ones—the aluminum fin covers the steel pipe perfectly, so corrosion shouldn't be an issue.

Really good quality, the ASME SA249 standard is the real deal. I was worried about the fins getting crushed during the long trip, but the packaging was top-notch—not a single one was bent.
