If you want to test the surface quality of 904L stainless steel plate, you usually have to wait until the pickling process after heat treatment. The pickling process can improve the smoothness and uniformity of the surface of 904L stainless steel plate. If the surface is not cleaned well before heat treatment, the quality will not meet the standard, and it will not meet the standard after pickling. Therefore, in order to improve the surface quality of 904L stainless steel plate, surface cleaning must be carried out before or during heat treatment. When the surface oxide scale of 904L stainless steel plate has uneven thickness, the surface roughness of the base metal surface displayed on various parts of the surface is also different, and in the pickling process, the dissolution of the surface oxide scale and the base metal at the scale attachment site The degree of corrosion by acid is not the same, so there will be uneven surface of 904L stainless steel plate. Oil is relatively easy to adhere to the surface of 904L stainless steel plate. The thickness and composition of the oxide scale on the attached part and other parts are different, and it will also...

For the production process of stainless steel decorative pipes, we are very familiar with it. A good-quality stainless steel pipe is reflected in each of its production processes. As a manufacturer of stainless steel decorative pipes, today we will briefly introduce the production process of stainless steel decorative pipes. 1. Material selection If you want to make high-quality stainless steel decorative pipes, what kind of raw materials should you choose? Of course, you should choose the steel belt of the refining furnace. The stainless steel pipes produced in this way are soft in material, high in brightness, and have smooth welds. The most important thing is strong corrosion resistance. It is more convenient to do deep processing such as pipe bending and welding, and the product quality is guaranteed. 2. Calendering After selecting the steel strip, it is necessary to choose the rolling manufacturer. The quality of the rolling process is directly related to the thickness of the finished stainless steel decorative pipe and the accuracy of the single weight. This is also an important factor affecting the cost accounting of agents and processors. link. 3. Pipe making This is an important link in the production of stainless steel pipes....
ULTIMET (UNS R31233) Antiwear and Aqueous Corrosion Cobalt Alloy From a wear standpoint it behaves similarly to STELLITE alloys with lower carbon content. From a corrosion standpoint it shares many of the properties of Type C and G HASTELLOY materials, especially resistance to chloride pitting and crevice corrosion. Its mechanical and welding properties are closer to HASTELLOY alloys than to STELLITE alloys, where their low ductility can be problematic. chemical composition: cobalt co: balance Chrome cr: 26 Tungsten w: 2 Molybdenum mo: 5 carbon c:0.06 Nickel ni: 9 Iron fe: 3 Silicon si:0.3 Nitrogen n: 0.08 Hardness hrc 28 Yield strength mpa 558 Tensile strength mpa 1020 Elongation% 33 While ULTIMET alloy has been used successfully in the form of wrought products, its largest application involves overlay welding, made from solid wire consumables and arc welding processes such as GMAW (MIG) and GTAW (TIG). Cobalt Alloys Anti-Abrasion and Aqueous Solution Corrosion Main Applications: Electroplating Rolls, Chemical Nozzles, and Biomedical Devices. Can provide forgings; harsh chemical industry environment (high corrosion resistance), can manufacture valves, pumps, nozzles.
