Specifications for Stainless Steel Grinding Jar 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 (BA0725) specifically designed for this jar.

Note: Other types of stainless steel are available upon request 316 or 316L for food and pharmaceutical applications, contact us today.
