There are some differences in the properties of stainless steel and brass sieves, while stainless steel is usually the superior.
Stainless Steel test sieves are constructed of stainless steel frame (AISI 304) and stainless steel woven wire mesh (either AISI 304 or 316):
- more durable
- non corrosive properties are not altered by water
- preferable for wet sieving, food applications, aggregates, mining, pharmaceuticals etc.
- required for large diameters: 315 mm, 350mm, 400mm, 450mm & 18"
Brass test sieves are constructed of brass frame (Cu:Zn) and stainless steel woven wire mesh (either AISI 304 or 316):
- was more cost efficient in the past
- less durable
- only very few applications where brass is chosen over stainless steel
- in some markets brass frame sieves are primarily requested due to tradition (South America for instance)
