Hydrogen cracks in stainless steel welding defects

The causes of hydrogen crack formation in welding arc welding of stainless steel are mainly caused by three factors, namely, the brittle and brittle hard and brittle structure of hydrogen produced by the welding process, the tensile stress acting on ...

Lamellar tearing defect of stainless steel plate in welding

Stratified tears may sometimes occur in rolled steel plates with poor thickness ductility. The main characteristic of lamellar tear is that it appears in the base metal parallel to the weld fusion boundary and the surface of the plate, usually ...

Creep reaction and test experiment of stainless steel plate

Creep is a slow failure mechanism, which may occur when stainless steel plates are exposed to higher than the elastic limit for a long time. Creep is very slow and not obvious at most ambient temperatures. For stainless steel plates, ...

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 ...

The effect of mechanical testing on stainless steel plates

Mechanical testing of stainless steel plates are used to generate data that can be used for design purposes or as part of the material connection procedure or operator acceptance procedure. The most important function may be to provide design data, ...

Factors influencing heat treatment of stainless steel plates after welding

In the heat treatment of stainless steel plates, tempering is mainly used to soften any hard microstructures that may be formed during the previous heat treatment, improve the ductility and toughness of the material. In addition, the tempering can also ...

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 ...

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 ...

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 ...

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 ...
