Why Consider Stainless Steel Mesh
Traditionally, it is common to find test Sieves made from three different material combinations: all stainless steel, all brass, or brass frames with stainless steel cloths. It is becoming more common to see companies discontinuing the production of brass test Sieves: both all brass and brass and steel mixed. There are multiple reasons why this is the case, but it all boils down to the quality and abilities of stainless steel. One of the main reasons that brass was ever used was because of its price point. Historically, brass was cheaper than steel; however, the metal market is different today and the price for both is much closer.
A big problem with brass is that it oxidizes. This will lead to tarnishing over time. Tarnishing can also lead to rust. For those still using brass Sieves, it is important to continually polish and clean the metal. This will extend the life of the brass, although stainless steel users do not have to worry about this problem.
Another added benefit of using stainless steel is that the product is more durable than brass could ever be. This is the case when it comes to abrasion resistance. Brass is a soft metal. Stainless steel is also sustainably more durable in terms of corrosion resistance. Stainless steel is preferable when using wet Sieves for the pharmaceutical and food industry. Because of the strength and durability of stainless steel, it is possible to create test sieves with large diameters. This makes stainless steel much more versatile.
Standard stainless steel test sieves are manufactured using 300 series, while the frame is made from 304 SS (this can change is specified). Other fabrication series include 304L SS, 316 SS, and finally 316L SS. Each of these series would constitute as a special order. The actual Sieve cloth (ASTM E11) is made from 304 SS, but it is available in other series as well. Each different type has different levels of carbon, magnesium, phosphorus, sulfur, and silicon. The steel also contains chromium, nickel, and nitrogen. 316L SS and 316 SS contain molybdenum.
Stainless steel screen mesh allows many different industries to easily conduct basic applications. Whether you are using stainless steel strainers or test Sieves, stainless steel is the way to go.
