Test method and test error of Brinell and Vivtorinox hardness for stainless steel plate and other metals

Brinell test was designed by Swedish researchers in early twentieth Century. As shown in Fig. 1 (a), the test involves pressing the hardened steel ball indenter into the surface of the sample using standard load. Select the diameter / load ratio to provide impressions of acceptable diameter. The diameter of the ball can be 10,5 […]

Attention to precipitation or aging hardening of stainless steel plates

Several methods can be used to increase the strength of stainless steel plates, which are alloying, quenching, working hardening, and a very common form of heat treatment, namely, precipitation or aging hardening. The so-called age hardening is in fact dependent on the formation of precipitates. In order to achieve the best combination of mechanical properties, the […]

Several defects and solutions occurred during the welding of stainless steel plate

When stainless steel plates are welded, defects often occur. The causes of these defects are different. This article describes some of the defect classification and avoidance methods. Stoma The pores formed by the stainless steel plate weld can be divided into internal pores, surface pores, and joint pores. There are two types of internal pores, one is […]

Introduction of the processing technology of S phase permeation layer on austenitic stainless steel plate

The performance characteristics of austenitic stainless steels are corrosion resistance, high toughness, and good processing performance is widely used in many fields, but the abrasion resistance and fatigue resistance of austenitic stainless steel is poor, which greatly affects the application life of the material products. Practice has proved that the austenitic stainless steel in high temperature nitriding […]

What are the preparations before welding stainless steel plates?

Stainless steel plate is a kind of composite plate with excellent corrosion resistance and corrosion resistance. Before welding, it needs a lot of preparation process, such as materials, tools, processing technology and so on. First of all, the stainless steel plate should be cleaned up before and after welding, and the surface of stainless steel plate […]
