Various industries report that some manufacturers have planned to cut production capacity due to the soaring cost of energy and raw materials. In the next year or two, European industrial manufacturing may not be able to meet the original demand.

Rockwell hardness Use diamond cone or quenched steel ball indenter to press the indenter into the material surface under the action of test pressure F. After holding for a specified time, remove the main test force and maintain the initial test force. Calculate the hardness value with the residual indentation depth increment. During actual measurement, the Rockwell hardness value can be directly read out through the dial of the testing machine. Indenter: a cone with a cone angle equal to 120 °, or a quenched steel ball with a diameter of D=1.588mm.

1.304 stainless steel. It is one of the most widely used austenitic stainless steels with a large amount of applications. It is suitable for manufacturing deep drawing formed parts, acid transmission pipes, vessels, structural parts, various instrument bodies, etc., as well as non-magnetic and low-t

The content of alloying elements. Generally speaking, steel with a chromium content of 10.5% is not easy to rust. The higher the content of chromium and nickel, the better the corrosion resistance. For example, the content of nickel in 304 material is 8-10%, and the content of chromium is 18-20%. In general, such stainless steel will not rust.
