설명
알루미늄 도금 강철 유형 1 is a carbon steel product coated with an aluminum-silicon alloy through a hot-dip process. The coating typically contains aluminum with approximately 5–11% silicon, which improves coating adhesion and enhances resistance to oxidation at elevated temperatures. This material is widely used in automotive exhaust systems, 산업용 난방 장비, and heat-resistant components.
Chemical Composition of the Coating
The coating composition plays a critical role in the performance of this material.
| 요소 | 일반적인 내용 (%) |
|---|---|
| 알류미늄 (알) | 89–95 |
| 규소 (그리고) | 5-11 |
| 철 (철) | 균형 (from substrate interaction) |
The aluminum-rich coating forms a protective oxide layer on the surface, while silicon reduces brittleness and improves coating uniformity during production.
기계적 성질
The mechanical properties mainly depend on the steel substrate grade used beneath the coating.
| 재산 | 일반적인 값 |
| 인장강도 | 270–450 MPa |
| 항복 강도 | 140–300 MPa |
| 연장 | 20–38% |
| 경도 | 55–85 HRB |
These properties provide a good balance between formability, 힘, and durability for fabrication processes such as stamping, 굽힘, 그리고 용접.
주요 성능 특성
우수한 내열성
The aluminum-rich surface can withstand continuous exposure to elevated temperatures. The protective aluminum oxide film reduces scaling and oxidation, making the material suitable for high-temperature service environments.
우수한 내식성
일반 탄소강에 비해, the aluminum-silicon coating provides significantly improved resistance to atmospheric corrosion. The coating acts as a barrier that protects the steel substrate from moisture and oxygen.
좋은 성형성
The coating remains strongly bonded to the steel surface during forming operations. Components can be rolled, 굽은, 스탬프가 찍힌, and fabricated without significant coating damage when proper processing methods are used.
반사율
The bright metallic surface reflects radiant heat effectively, which is beneficial for thermal shields, 오븐, 용광로, and heat-management applications.
