天津华安旭阳全部贸易有限公司供应优质Hastelloy D205高硅耐蚀合金板材、棒材、丝材，厂家直销，价格合理，质量保证，交货期快！

Hastelloy D205作为耐蚀合金的知名度并不高，但是它有较强的耐各种氧化性酸的能力，因为它含有20%的铬和5%的硅，因为它也适用于生产板式换热器。

Hastelloy D205是的高硅合金，其主要优点在于其的加工性能，良好的耐高温脆性能力以及在各种浓度的硫酸中的不错耐腐蚀性能。Hastelloy D205还具有良好的抗应力腐蚀能力，以及比316L不锈钢和Fe-17Cr-20Ni-5Si更好的耐点蚀能力。

由于以上特性，Hastelloy D205是制作硫酸设备和板式换热器的理想材料。同时，也可以作为在具有高氧化性的介质中使用的相关硬件材料。此外，通过时效处理，该合金的屈服强度可以提高一倍以上。

板（带）厚度：0.38~3.规格

棒：直径12.7 ~ 95.2mm

丝：直径0.89~3.18mm

Hastelloy D205 Corrosion Resistant Alloy

HASTELLOY D205 is not a well-known nickel alloy but with 20% chrome and a 5% silicon content is extremely resistant to oxidizing acids and thus well suited to applications such as plate heat exchanges.

HASTELLOY D-205 alloy is an advanced high-silicon alloy based on the Ni-20Cr system. Its chief advantages over high silicon-iron based alloys (e.g. Fe-17Cr-20Ni-5Si) are excellent formability, good resistance to elevated-temperature embrittlement, and superior performance in many concentrations of sulfuric acid. D-205 alloy also possesses high resistance to stress corrosion cracking and is considerably more resistant to pitting corrosion than Type 316L Stainless Steel and Fe-17Cr-20Ni-5Si alloys.

Given these attributes, D-205 alloy constitutes an ideal sulfuric acid, plate-heat-exchanger material. Also, the alloy is very useful for all hardware involved with the processing of highly oxidizing media. An added benefit is that the yield strength of D-205 can be more than doubled (from 49 ksi to 104 ksi) by age-hardening.
