Tailored for engineers and procurement specialists, UNS S46800 offers a cost-effective solution for moderately corrosive environments. Explore related grades like sa240/a240 uns s41003to meet diverse project requirements.
ASME SA240/ASTM A240 UNS S46800, a ferritic stainless steel, features 18.0-20.0% chromium and titanium stabilization (0.10-0.60%), delivering excellent corrosion resistance, superior weldability, and moderate strength. Designed for applications requiring durability in moderately corrosive environments, such as automotive exhaust systems and industrial equipment, it benefits from titanium stabilization and low carbon content (≤ 0.03%) to prevent carbide precipitation during welding, outperforming non-stabilized grades like sa240/a240 uns s43000. Its ferritic structure ensures robust scaling resistance up to 850°C (1562°F).
Gangsteel highlights that UNS S46800 offers superior corrosion resistance compared to sa240/a240 uns s41008 due to higher chromium content and stabilization, and it is more cost-effective than high-alloy grades like sa240/a240 uns s44400. Its weldability and affordability make it ideal for automotive and industrial applications.
Key benefits include:
Case Study: An Indian automotive manufacturer used UNS S46800 sheets for exhaust components, achieving a 20% reduction in welding defects compared to sa240/a240 uns s43035 due to its titanium stabilization.

Q: How does UNS S46800 compare to UNS S44400 in corrosion resistance and applications?
A: UNS S46800, with 18.0-20.0% chromium and titanium stabilization, offers excellent corrosion resistance (PREN ~18.0-20.0) but is less resistant than sa240/a240 uns s44400 (PREN ~20.5-24.5) due to the latter’s molybdenum content. UNS S46800 is ideal for automotive exhausts and industrial equipment, while UNS S44400 suits chemical processing due to enhanced chloride resistance.
Q: Is UNS S46800 suitable for automotive exhaust systems, and how does it compare to UNS S41003?
A: Yes, sa240/a240 uns s46800 is highly suitable for automotive exhaust systems due to its excellent corrosion resistance and superior weldability up to 850°C (1562°F). Compared to sa240/a240 uns s41003, with lower chromium (10.5-12.5%), UNS S46800 offers better corrosion resistance and weldability, making it ideal for exhausts, while UNS S41003 is better for structural applications.
Q: What is the price difference between UNS S46800 and UNS S44700, and what drives this difference?
A: UNS S46800 is priced at USD 3-5 per kg (FOB), significantly lower than sa240/a240 uns s44700 (USD 5-7.5 per kg) due to its lower chromium (18.0-20.0% vs. 28.0-30.0%) and lack of molybdenum. Factors like alloy content, market demand, and production complexity drive the price difference.
