Advantages and disadvantages of adding titanium in austenitic stainless steel

When chromium – nickel austenitic stainless steel is heated to the temperature range of 450-800 C, corrosion often occurs along the grain boundary, which is called intergranular corrosion. Generally speaking, intergranular corrosion is actually carbon element precipitated from Cr23C6 in the metallographic structure of saturated austenite, resulting in poor austenite structure at grain boundaries. Therefore, it is […]

Factors to be paid attention to in the process of solid solution processing for stainless steel pipes

During the process of solid solution treatment, stainless steel pipes need to pay attention to the influence of protective atmosphere, temperature and cooling speed. The first is the light online solution treatment procedures, stainless steel pipe in the production process caused by rolling, drawing and welding heat effect, will lead to pipe structure and mechanical property will […]

What are the difficulties in the welding process of the duplex stainless steel 2205

There are some technological difficulties in the actual welding of duplex stainless steel 2205, but in fact, if we grasp 2205 of the related material characteristics, many problems will be solved when welding is processed. Here are the following aspects. First, compared with the first generation duplex stainless steel, 2205 has further increased the nitrogen content, […]

Performance comparison between stainless steel pipe and other water supply pipe materials

At present, most of the water pipes are concealed and pipe wells. If the material selection is wrong, it is likely to cause huge losses. The common water supply materials include stainless steel pipes, copper pipes, galvanized pipes, composite pipes and plastic pipes. Next, we will compare these materials to see which material is the most suitable. […]

Surface treatment process of stainless steel pipeline

Improving the surface quality of stainless steel pipelines, including improving the surface morphology and structure, and reducing the number of layers, the common surface treatment methods at present are mechanical drawing, mechanical lapping, polishing and burning. Mechanical drawing The mechanical drawing is to increase the surface roughness of the pipeline by using the plug bolt precision […]

What are the production characteristics of stainless steel seamless steel pipes

There are four kinds of stainless steel seamless steel pipe production methods: hot rolling, hot extrusion, cold rolling and cold drawing. Their production characteristics from plastic deformation resistance, and spread, several aspects of this application and the sensitive degree of thermal conductivity and oxidation resistance of observation. The following are described in detail. Plasticity Martensitic stainless steel […]
