Yingdu supplies York 326, York 431, York 931 Style 316L stainless steel demister pads

SS 316 and SS 304 are the most commonly used stainless steel alloys for manufacturing demister pads. Stainless Steel 316 Demister Pad is a better option for applications in corrosive and high-temperature environments while ss304 demister pad is applied for projects requiring less resistance and strength.

Differences between SS 316 demister pads and SS 304 demister pads:

1, SS 316 pad demister is more corrosion resistant than SS 304 product. This makes it ideal for use in environments with high chemical concentrations, such as oil refineries, chemical plants, and power plants.
2, SS 316 demister pad can be used in temperatures up to 900°F (482°C), whereas SS 304 demisters can only tolerate temperatures up to 600°F (316°C).

3, SS 316 also offers greater mechanical strength than SS 304 due to its higher chromium content. SS 316 contains at least 16% chromium and 10% nickel, while SS 304 contains at least 18% chromium and 8% nickel. Consequently, SS 316 is better able to resist environmental and mechanical pressures without bending or deforming.

4, SS 316 is more expensive than SS 304 due to its higher resistance and strength.

5,SS 316 material offers a smoother surface than SS 304, with a higher "luster" finish. This makes it more attractive to some users and projects.
