Product Description

ASME SA423 GR.1 Low Alloy Steel Welded Tube For Boiler and Superheater Application

ASME SA423 Grade 1 Electric Resistance Welded (ERW) tube is a low-alloy steel tube that is manufactured using the electric resistance welding process. This type of tube is part of the ASME (American Society of Mechanical Engineers) SA423 specification, which deals with low-alloy steel tubes that are intended for use in applications that require resistance to atmospheric corrosion. It is also designed for high-temperature and high-pressure service, particularly in boilers and heat exchangers.

Key Features:

1. Material Composition:

Chemical Requirements
Composition, %
	Grade 1	Grade 2	Grade 3
Carbon, max	0.15	0.15	0.15
Manganese	0.55 max	0.50–1.00	0.70–1.40
Phosphorus	0.06–0.16	0.04 max	0.020 max
Sulfur, max	0.060	0.05	0.020
Silicon	0.10 min	...	0.55 max
Copper	0.20–0.60	0.30–1.00	0.25–0.45
Chromium	0.24–1.31	...	...
Nickel	0.20–0.70	0.40–1.10	0.50 max
Molybdenum	...	0.10 min	0.20 max
Antimony	...	...	0.05–0.15

2. Mechanical Properties of ASME SA423 Grade 1 ERW Tubes

Property	Grades 1 and 2	Grade 3
Tensile Strength	415 MPa (60,000 psi)	380 MPa (55,000 psi)
Yield Strength	255 MPa (37,000 psi)	230 MPa (33,000 psi)
Elongation, min (%), (in 50 mm / 2 in)	25	35
Hardness (Brinell/Rockwell)	≤ 170 HBW / ≤ 87 HRB

3. Standards & Specifications:

ASME SA423: Standard specification for seamless and welded low-alloy steel tubes for boilers and superheaters.
Grade 1: A specific grade under this standard, optimized for high-temperature service.
Complies with ASME Boiler and Pressure Vessel Code (BPVC) Section II for material properties.

4. Testing & Inspection:

Hydrostatic testing, ultrasonic testing (UT), or eddy current testing to ensure weld integrity.
Chemical and mechanical property verification per ASTM/ASME standards.

5. Advantages of SA423 Grade 1 ERW Tubes

Advantage	Description
Cost-Effective	Cheaper than seamless tubes while maintaining high strength and durability.
High-Temperature Resistance	Chromium-molybdenum (Cr-Mo) alloy provides excellent creep resistance at temperatures up to 450°C (850°F).
Good Weldability	ERW process ensures a strong, uniform weld without filler metals, reducing defects.
Consistent Quality	Precise dimensional control (OD, wall thickness) for reliable performance in pressure applications.
Corrosion Resistance	Low-alloy steel composition resists oxidation and scaling in steam/high-heat environments.
Easier Fabrication	ERW tubes can be easily bent, flared, and welded into complex systems.
Faster Production	ERW manufacturing is quicker than seamless tube production, ensuring better availability.
ASME Compliance	Meets strict Boiler & Pressure Vessel Code (BPVC) standards for safety and reliability.

Comparison with Other Grades:

SA423 Grade 1 vs. SA213 T11/T22: While SA213 covers similar Cr-Mo alloys, SA423 Grade 1 is specifically for ERW tubes, offering a balance of performance and affordability.
