Reasoning Behind Material Selection
Mild Steel Coil:
Ideal for less aggressive environments where cost-effectiveness is a priority. Suitable for solutions like acetic acid and salt brine in metal finishing processes.
Stainless Steel 304 Coil:
Chosen for environments that are mildly corrosive, particularly in low-concentration alkaline cleaners. Often preferred for grid coils and general metal finishing applications.
Stainless Steel 316 Coil:
The go-to material for most plating solutions, including those used in grid coils and metal finishing, due to its superior corrosion resistance in environments with higher acid concentrations or chlorides.
Titanium Coil:
Best for highly corrosive environments, especially those involving chlorine gas or hydrochloric acid, where other materials might fail. Ideal for specialized chemical processing solutions in metal finishing.
PVDF (Polyvinylidene Fluoride) Heat Exchanger:
Selected for its high chemical resistance in harsh environments, particularly where metal alternatives might corrode. Suitable for use in aluminum bright dip and chromium plating solutions in grid coils and metal finishing processes.
