Why SA240 304H Excels in Corrosion Resistance

In aggressive environments, ASME SA240 304H TP304H(S30409) stainless steel plates outperform competitors. The high chromium content (18-20%) forms a stable passive oxide layer, providing excellent resistance to oxidation at temperatures up to 870°C, far surpassing carbon steels. This makes it perfect for boiler applications and petrochemical furnaces. Independent tests by NACE confirm its resistance to intergranular corrosion post-welding, thanks to the controlled carbon design.

At Gangsteel, we leverage advanced pickling lines to enhance surface passivation, ensuring your SA240 304H plates arrive ready for immediate use. Compare with sa240/a240 uns s31609.

FAQ: Common Questions About ASME SA240 304H TP304H(S30409) Stainless Steel Plate

 

What is SA240 304H stainless steel used for?

SA240 304H(304H) is a high-carbon austenitic stainless steel primarily used in high-temperature applications like boiler tubes, superheaters, and pressure vessels in power generation and petrochemical industries. Its elevated C (0.04-0.10%) provides superior creep resistance up to 870°C, while maintaining corrosion resistance in mildly oxidizing environments. Gangsteel supplies ASME/ASTM plates for heat exchangers, with use in steam lines reducing failures 25% vs. standard 304. For low-temp, see sa240/a240 uns s30403.

 

What are the differences between SA240 304H and 304 stainless steel?

SA240 304H(304H) differs from 304 (S30400) with higher C (0.04-0.10% vs. ≤0.08%) for better creep at 600-870°C, while matching corrosion resistance (PREN ~18). 304 is general; 304H high-temp. Cost: 304H 5% higher for C. Gangsteel recommends for boilers. Equiv: sa240/a240 uns s31008.

 

Is SA240 304H stainless steel weldable?

Yes, SA240 304H welds well with GTAW/SMAW using ER308H fillers; high C risks sensitization, so preheat 100°C, no PWHT needed but optional 1050°C for heavy sections. ASTM A262 confirms no IGA post-weld. Gangsteel certs for cyclic, thick-plate with low distortion. Protocols: sa240/a240 uns s31609.

 

What is the density of SA240 304H stainless steel?

The density of ASME SA240 304H TP304H(S30409) stainless steel plate is 8.0 g/cm³ (0.289 lb/in³), typical for austenitics, enabling lightweight designs in boilers without compromising strength. Gangsteel optimizes shipping.

 

How much does SA240 304H stainless steel cost per kg?

Gangsteel offers SA240 304H at approximately $1.25-$1.75 per kg for standard plates (FOB basis). Thicker or custom adds 10-15%. Contact admin@gangsteel.com for rates, influenced by carbon surcharges. Bulk 15% off. Compare sa240/a240 uns s30400.

 

Can SA240 304H be heat treated?

SA240 304Hsolution anneals at 1050-1120°C (quench) for carbide dissolution; high C boosts creep, no hardening, stress-relieve 650-850°C post-form. Avoid 425-860°C sensitization. Gangsteel treats with verification. Consult for sa240/a240 uns s31008.

 

What certifications are available for Gangsteel SA240 304H plates?

Gangsteel's SA240 304H plates include EN 10204/3.1 MTCs, PMI/UT, third-party (SGS/BV) for ASME/ASTM/PED. ISO 9001 traceability; optional high-temp quals like ASTM A262. More: sa240/a240 uns s31609.
