50 ml Stainless Steel Planetary Milling Jars with Media - 304 Grade
Specifications for Stainless Steel Grinding Jars with Milling Media
- Grade 304 is the most widely used austenite steel, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless (not to be confused with A2 grade steel, also named Tool steel, a steel).
- The grinding jars are extensively applied to in the fields of Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection, Paint, Ink, geology and so on.
- Each jar set includes grinding jar, jar lid, rubber sealing gasket, and a milling media set (BA0723) specifically designed for this jar.
Note: Other types of stainless steel are available upon request: 316 SS or 316L for food and pharmaceutical applications, contact us today.
