Nowadays, the industrial sector places great emphasis on the corrosion resistance materials when making selections, among which 904L high temperature alloy coil stands out for its excellent corrosion resistance and reliability. So, what characteristics make 904 high temperature alloy coil the best material for various industries?
904L high temperature alloy coil enhances its corrosion resistance by adding copper elements. Compared to other stainless steel coils,904L contains a higher proportion of nickel and chromium, which not only endows 904L high temperature alloy coil with better resistance to chloride attack but improves its stability, acid resistance, and alkali resistance in extreme environments. These properties allow 904L to exhibit excellent corrosion resistance in sulfuric and phosphoric acid environments enabling it to perform well under high concentration and high temperature conditions.
904L is a low-carbon, high-nickel, high-molybdenumustenitic type. 904L has an excellent ability to transition from activation to passivation. The higher nickel content and molybdenum content greatly reduce the rate of 904L. The addition of alloy element copper gives 904L strong resistance to acid, especially for chloride gap corrosion and resistance to cracking corrosion It has excellent corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and good pitting resistance neutral chloride-containing media. It also has good resistance to crevice corrosion and stress corrosion cracking. It is suitable for various concentrations of sulfuric acid below 70℃ Its corrosion resistance is also very good in acetic acid, formic acid, and mixed acid of acetic acid at any concentration and any temperature at atmospheric pressure.
904L high temperature alloy coil also has excellent welding and forming capabilities, which allows it not only to play a role in industries such as petrochemicals but also in industries that require precision processing. 904L high temperature alloy coil has many advantages and can be applied to many fields, making it a very good material.
