In order to enhance the surface quality of stainless steel pipelines, optimization of the surface morphology and application of structure, reduce the energy level and the number of dielectric layers, need to do some processing on stainless steel pipeline system, mainly divided into mechanical drawing, mechanical grinding, polishing, pickling and passivation, feather cloth light burning blunt, […]
Strength difference of various kinds of stainless steel materials
The strength of stainless steel is affected by various factors, and the most important and basic is the chemical elements added to the chemical composition. Therefore, the strength of the ferrite, martensite and austenitic stainless steel is different because of the differences in their chemical composition. Martensitic stainless steel has the characteristics of hardening by quenching, so […]
Reasons and preventive measures for magnetic properties of austenitic stainless steel in cold processing
It is well known that the vast majority of stainless steel materials are suitable for cold forming. Austenitic stainless steel itself is not magnetic, but cold processed austenitic stainless steel will have strong magnetic properties, especially those made of austenitic stainless steel, such as head, elbow and so….. Why will the austenitic stainless steel suddenly appear to […]
The reason for the performance of stainless steel pipes in refining furnace are stronger than that of medium frequency furnace
At present, there are mainly two kinds of stainless steel pipes smelting furnaces on the market. They are mainly refining furnaces and intermediate frequency furnaces. The quality of stainless steel pipes produced by them is obviously different, and the stainless steel pipes produced by refining furnaces are superior in performance. What is the refining furnace? Refining under […]
Performance comparison of stainless steel welded pipe with polished welded pipe
At present, industrial stainless steel welded pipe is widely used in the application market of stainless steel at home and abroad. Among them, because of the difference of surface processing technology, the stainless steel industrial welded pipe is mainly divided into two kinds of welded pipe and polished welded pipe. The following are the principles and advantages […]
Causes of stress corrosion on the surface of stainless steel pipe
When the stainless steel pipe is used for a long time, some oxidation phenomena will appear on the surface of the pipe. Good maintenance is only the extension of the oxidation. So why does the surface of the stainless steel pipe appear to be oxidizing? In fact, these surface oxidation is caused by corrosion of stainless steel […]
Surface defects and preventive measures of stainless steel plates
In the use of stainless steel plate, in order to ensure that the results meet the requirements, need to pay attention to board surface defects may occur, such as small crack, crack, crack, edge peak shaped inclusions and scabs all will have a negative impact on the surface quality of stainless steel plate, and ultimately reduce […]
Causes of tensile cracking of stainless steel pipes and preventive measures
Sometimes the cracking phenomenon of tensile stainless steel pipe, the scene appears diversified, there are four kinds of common, respectively after tensile deformation, from the die exit occurs immediately after tensile deformation, impact or vibration occurs after tensile deformation, there is a section of time or in use. The main reasons are low ductility, high modulus […]
Characteristics and applications of hot rolled stainless steel plate
Although the conventional hot rolling stainless steel plate surface quality is poor, but in fact only for surface oxidation and finish low, other performance is good, such as plasticity, toughness and mechanical strength were higher, to corrosion of acid and alkaline gas and solution medium, and is also a kind of not easy rusty alloy steel material. […]
Selection and analysis of stainless steel fasteners
There are many available to make the fasteners material, which are made of stainless steel fasteners not only the appearance of texture better, higher strength and better corrosion resistance, which can also better machining and welding, and stainless steel fasteners can be electroplated or heat treatment, in order to obtain higher performance, in addition to be 100% […]
