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 […]

What is the reaction of stainless steel plates and hydrogen

Hydrogen corrosion may occur in ammonia synthesis, hydrogen desulfurization and hydrogenation and petroleum refining units. Carbon steel is not suitable for high pressure hydrogen installations at temperatures above 232 C. Hydrogen can spread into the stainless steel plate and form methane at the grain boundary or in the pearlite zone with the iron carbide. Methane can not […]

Several processes of pickling and passivation on the surface of stainless steel plate

When the surface of the stainless steel plate is not annealed (for example, the surface after welding), drilling mud residue, rust-proof film, or ferrite impregnated with stainless steel after the molding process, the corrosion resistance of the stainless steel material will be directly affected. At this point you need to use acidic oil cleaning agent to do […]

What harm does salt spray corrosion cause to passivation film on the surface of stainless steel plate?

Salt spray corrosion will destroy the passivation film on the surface of the stainless steel plate, so that the decorative nature of the plate will be lost, and the mechanical strength of the material will be reduced. Some electronic components and electrical wiring will cause the power line to be interrupted due to corrosion, especially in […]

Combination of tensile stress and specific corrosive environment may rupture stainless steel plates

The combination of tensile stress and a specific corrosive environment can cause the stainless steel plate to break. This type of attack is called Stress Corrosion Cracking (SCC). The most common environmental exposure condition that causes SCC in stainless steel is the presence of chloride. Although the degree of stainless steel immunity to chloride SCC is large, […]
