Frequently Asked Questions
This product is a highly corrosion-resistant STS featuring an outstanding sacrificial anode reaction, beautiful appearance, and exceptional resistance to corrosion in salt and condensed water.
The material offers outstanding red rust resistance at temperatures up to 472℃ and oxidation resistance up to 843℃, thanks to its protective coating layer.
It is primarily used in automobile exhaust systems (cold-end parts like center pipes, mufflers, and tail pipes), building interior/exterior structural components, and fuel cell or solar cell panel modules.
ASTM A 463 FSS Type 409 (A-STS 409L) has a Yield Point (YP) of 170-345 N/mm² and Elongation (EL) of ≥20%. In comparison, FSS Type 439 (A-STS 439) offers a higher YP of 205-415 N/mm² and EL of ≥22%.
Yes, besides providing excellent oxidation and corrosion barriers, the coating layer delivers an outstanding decorative tendency suitable for visible building interior and exterior designs.
