Common chemical elements in stainless steel plate

There are more than 10 kinds of common elements in stainless steel plate. In addition to the basic element iron, the most important elements affecting the performance and microstructure of stainless steel plates are carbon, chromium, nickel, manganese, silicon, molybdenum, titanium, niobium, titanium, manganese, nitrogen, copper, cobalt and so on. When some elements coexist in the […]

Introduction of mechanical properties and stamping process of stainless steel plate

Stainless steel plate can be used to make a lot of daily necessities, stainless steel processing technology is diverse, such as stamping, bending, shear folding, etc., this paper focuses on stamping process. The common stamping forming processes of stainless steel sheet include drawing process, bulging process, flanging process (including reaming) and bending process. The corresponding material […]

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 […]

Two types of development and application of duplex stainless steel

The advantage of duplex stainless steel is its excellent corrosion resistance, especially local corrosion resistance. In addition, its strength is equivalent to two times of austenitic stainless steel, toughness is also very good, not only for the traditional paper-making and chemical processing industry equipment, but also used in important public engineering fields, such as bridges and highway […]

Pickling process of stainless steel materials

Because of its excellent mechanical properties, high hardness and wear resistance, stainless steel has been widely used in the military parts processing field. Their surface treatment is carried out after heat treatment, solid solution and aging, because the heat treatment process of those thicker oxide skin and material itself has some particularity, resulting in pickling passivation processing […]

The condition of stress corrosion cracking is caused by stainless steel

Chromium martensitic stainless steel and ferritic stainless steel according to different conditions can cause stress corrosion cracking (mainly intergranular cracking) or hydrogen embrittlement, but this kind of stainless steel in MgCI2 or NaCI solution, resisting performance is far stronger than austenitic stainless steel, and under the condition of load stress is not strong, will not cause cracking. The austenitic stainless […]

Performance analysis of series 317 series stainless steel

317LXN, 317LX and 317L are austenitic stainless steels containing alloying element molybdenum, which have better corrosion resistance than common chromium nickel austenitic stainless steel. In addition, the creep resistance and stress cracking resistance of 317XN, 317LX and 317L stainless steel at high temperature are better than that of 304 stainless steel. The comprehensive performance of the […]

The role of various major chemical elements in stainless steel

The chemical elements are often used in the steel industry, there are about more than 20 species, isstainless steel, commonly used elements of a dozen, in addition to iron, can affect the microstructure and properties of stainless steel elements are carbon, chromium, nickel, manganese, silicon, molybdenum, titanium, niobium, titanium, manganese, cobalt, copper, nitrogen etc.. When […]
