Frequently Asked Questions
Q: What is A-STS (Aluminized Stainless Steel)?
A: A-STS refers to aluminized stainless steel, which is stainless steel coated with an aluminum-silicon alloy. This combination offers excellent sacrificial anode protection and superior corrosion resistance.
Q: What are the primary applications of A-STS 409L and 439?
A: They are widely used in automotive exhaust systems (specifically cold-end parts like mufflers, tail pipes, and center pipes), building interior/exterior materials, and solar cell or fuel cell panel modules.
Q: How does A-STS perform under high temperatures?
A: Thanks to the specialized coating layer, A-STS exhibits outstanding red rust resistance up to 472℃ and excellent oxidation resistance up to 843℃.
Q: What standards do A-STS 409L and 439 comply with?
A: These products comply with the ASTM A 463 order specifications for Ferritic Stainless Steel (FSS) Type 409 and Type 439.
Q: What are the mechanical property differences between A-STS 409L and A-STS 439?
A: A-STS 409L features a yield strength (YP) of 170-345 N/mm² and elongation (EL) of ≥20%. A-STS 439 offers a higher yield strength of 205-415 N/mm² and elongation of ≥22%.
