HASTELLOYC4ndi aloyi wopangidwa ndi Nickel, chromium, ndi molybdenum. Imawonedwa ngati aloyi yosunthika kwambiri polimbana ndi dzimbiri. aloyi izi zikusonyeza kukana mapangidwe tirigu malire precipitates pamene pansi kuwotcherera kutentha, kupanga izo oyenera ntchito zosiyanasiyana mankhwala ndondomeko yake welded boma. Komanso, AlloyC4Imawonetsa kukana kwabwino kwa pitting, kupsinjika-kusweka kwa dzimbiri, ndi mpweya wa oxidizing mpaka 1900 ° F. Ili ndi kukana kwapadera kumadera osiyanasiyana amankhwala.
APPLICATIONS:
1.Paper industry: Digesters ndi bleach zomera.
2.Magawo a mpweya wowawa: Zinthu zomwe zimawonekera ku gasi wowawasa.
3.Flue-gas desulfurization zomera: Zida zogwiritsidwa ntchito mu flue-gas desulfurization zomera.
4.Mapangidwe a sulfuric acid: Ma evaporator, osinthanitsa kutentha, zosefera, ndi zosakaniza zomwe zimagwiritsidwa ntchito m'madera a sulfuric acid.
5.Sulfuric acid reactors: Zida zomwe zimagwiritsidwa ntchito mu sulfuric acid reactors.
6.Organic chloride process: Zida zomwe zimagwiritsidwa ntchito popanga organic chloride.
7.Halide kapena acid catalyst process: Zida zogwiritsidwa ntchito munjira zomwe zimagwiritsa ntchito halide kapena acid catalysts.
