자동 머플을위한 ASTM A463 T1 40 AS240 AS300coil, 예 Aluminized 실리콘 스틸 하우스 파이프

Aluminized steel is carbon steel coated, through the hot-dip process, with an aluminum-silicon alloy. The aluminum coating provides resistance to high temperatures and a bright appearance. The silicon promotes better adherence of the coating to the base metal. Aluminized sheet and coil will maintain their bright appearance and provide long-term service at temperatures up to 900 degrees F – a higher temperature than comparable zinc-coated products can withstand. Even though aluminum corrodes faster than zinc, the oxide that forms on aluminum adheres tightly, protecting the base metal.

APPLICATIONS

Used for high heat applications, A463 is used for firewalls, heaters, incinerators, ovens, dryers and their housings.

Aluminized sheet and coil will maintain their bright appearance and provide long-term service at temperatures up to 900 degrees F – a higher temperature than comparable zinc-coated products can withstand. Even though aluminum corrodes faster than zinc, the oxide that forms on aluminum adheres tightly, protecting the base metal.

1.Automobile exhaust pipe, Fuel tank

2.Combustion furnace, heat exchanger, dryer, air conditioner, etc

3.Household water heater, gas stove, bread box, chimney, microwave oven

Advantages & characters of aluminium silicon steel:

1.High temperature resistance: due to the specific combination of steel plate substrate and coating structure, an iron-aluminum alloy is formed, which makes the coated aluminum plate have excellent high temperature resistance.  High reflectivity can be guaranteed at 450℃.

2.Thermal reflectivity: at 480 ℃, the plate can reflect 80% of the incident heat.  Therefore, the aluminum-silicon plate can be made into an efficient heat insulation barrier or a heat reflector in high-temperature application, and the temperature in the furnace can be rapidly increased through effective heat reflection.

3.Mechanical strength: under room temperature, the mechanical strength of the aluminum plating plate is consistent with that of its base material.  At the same high temperature of 480℃, the strength of aluminized steel plate is 10 times that of aluminum plate, so the thickness of steel plate can be reduced by at least 30%

4.Corrosion resistance: In the hot dip plating process, molten aluminum reacts with oxygen in the air to form an Al2O3 protective layer, which passivates the surface of the steel plate immediately.

5. 생태 학적 특성 : 화학적 부동태 화가 없는 알루미늄 도금 판은 건강에 영향을 미치지 않으므로 식품 가공에 사용할 수 있습니다. 많은 전문가 그룹의 테스트 보고서는 인체에 ​​무해하며 환경 보호 제품임을 확인했습니다. 알루미늄 도금은 스테인레스 스틸 과 비교할 수   있지만 가격은 스테인레스 스틸보다 약 1/3에 불과합니다.
