ASTM A423 / ASME SA423 Grade 1 ERW Carbon Steel Tube Heat Exchanger Tube

ASTM A423 / A423M Grade 1 is a standard specification for seamless and electric-resistance-welded (ERW) low-alloy steel tubes intended primarily for heat exchangers, condensers, and similar pressure vessels. The "Grade 1" is a carbon-manganese-copper steel known for its improved atmospheric corrosion resistance compared to plain carbon steel, while being more cost-effective than stainless steels.

Comparison with Other Common Heat Exchanger Tubes

Material	Pros	Cons	Best For
ASTM A423 Gr.1	Good atmospheric corrosion resistance, cost-effective, good weldability/ductility.	Not for highly corrosive environments. Lower strength than some alloys.	Mildly corrosive cooling water, environments where condensation causes carbon steel to rust.
ASTM A179 (C.S.)	Low cost, excellent thermal conductivity, readily available.	Poor corrosion resistance, prone to rust.	Non-corrosive services (closed-loop cooling, oil).
ASTM A423 Gr.2	Better corrosion resistance than Gr.1 due to added Nickel.	Slightly higher cost than Gr.1.	More aggressive environments than Gr.1, but not severe enough for stainless.
ASTM A249 TP304 (SS)	Excellent corrosion resistance, high strength.	Higher cost, prone to stress cor

Why Choose ASTM A423 Gr.1 ERW Tube?

You would specify this material when:

The service environment (air or water) causes premature failure of carbon steel tubes due to rusting.
The operational cost of unexpected downtime and tube replacement outweighs the slightly higher initial material cost compared to A179.
The corrosion conditions are not severe enough to justify the expense of stainless steel (A249) or copper-nickel alloys.
You need a reliable, code-compliant (ASME SA423) material that offers a proven balance of performance, fabricability, and life-cycle cost.

Applications

This material is selected for specific service conditions where carbon steel isn't enough, but stainless is overkill.

Power Plant Feedwater Heaters
Condensers (especially with cooling water that is mildly corrosive)
Industrial Heat Exchangers in chemical and petrochemical plants
General Service Heat Exchangers exposed to atmospheric corrosion or where longer life is desired over carbon steel.
