Aluminized stainless steel features high corrosion resistance, outstanding sacrificial anode reaction, excellent resistance to corrosion in salt and condensed water, red rust resistance up to 472℃, oxidation resistance up to 843℃, and a beautiful decorative appearance.
It is commonly used in automobile exhaust systems (specifically cold-end parts like center pipes, mufflers, and tail pipes), building interior/exterior architectural elements, and fuel cell or solar cell panel modules.
Yes, one of its primary advantages is excellent weldability and ease of fabrication. It can be easily formed, bent, and shaped to meet complex design requirements, making it a cost-effective choice for various manufacturing applications.
It offers outstanding red rust resistance up to 472℃ and high-temperature oxidation resistance up to 843℃ due to its protective coated layer.
According to industry standards, FSS Type 409 (A-STS 409L) has a Yield Strength (YP) of 170-345 N/mm² and Elongation (EL) of ≥20%. FSS Type 439 (A-STS 439) offers higher strength with a Yield Strength of 205~415 N/mm² and Elongation of ≥22%.
