Low Temperature Performance of Stainless Steel Welded Pipe
Low Temperature Performance of Stainless Steel Welded Pipe2022-01-17 Posted by WilsonLow temperature performance of stainless steel welded pipe is shown below1. Low temperature embrittlement In low temperature environment, the deformation energy is small. In low temperature environment, the elongation and the decrease of the shrinkage of the section are called low temperature embrittlement. And more in the ferrite series...
304 Stainless Steel Pipe Annealing Requirements
NEWS304 Stainless Steel Pipe Annealing Requirements2022-01-17 Posted by WilsonThe annealing requirements for 304 stainless steel pipe are as follows:1, Whether the annealing temperature reaches the specified temperature. 304 stainless steel pipe heat treatment is generally taken to solve the heat treatment, which is commonly known as the “annealing”, the temperature range of 1040 ~ 1120 ℃ (Japanese standard). You can also...
Technical Requirements for Stainless Steel Tubes
Technical Requirements for Stainless Steel Tubes2022-01-17 Posted by WilsonTechnical requirements for stainless steel tubes are following below:(1) Good corrosion resistance. The most basic requirements for stainless steel tube is corrosion resistance, that is, according to the use of different conditions, requiring steel pipe can withstand general corrosion, intergranular corrosion, point corrosion, stress corrosion. For...
How to Distinguish the Austenite and Ferrite Stainless Steel in Use
How to Distinguish the Austenite and Ferrite Stainless Steel in Use2022-01-17 Posted by WilsonIndustrial use of stainless steel according to the metallographic organization can be pided into three categories: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel. It can be the characteristics of these three types of stainless steel (as shown in the table below), but it should be noted that the...
he Production Environment of Stainless Steel Welded Pipe
The Production Environment of Stainless Steel Welded Pipe2022-01-17 Posted by WilsonThe production quality of stainless steel welded pipe is affected by many factors, including the environmental factors of the production site, stainless steel welded pipe manufacturers in the product quality control can not be ignored when the impact of this part. Here to talk about stainless steel welded pipe production environment control...
Package of Steel Tube
Package of Steel Tube2022-01-17 Posted by WilsonPackage of steel tube requirements substantially pided into two categories: one is the common type of bale, and the other is with totes similar container load.Bundled packageAvoid pipe damage by baling and transportation process, baling signs to a uniform and consistent.The same bundle of steel pipe should be the same furnace number (Lot), with the steel grade, the same specifications...
Difference between GI and MS
Galvanized iron is iron which has been coated in a layer of zinc to help the metal resist corrosion. Steel can also be galvanized. When metal is going to be used in an environment where corrosion is likely, it is often galvanized so that it will be able to withstand the conditions. Even with galvanization, however, corrosion will eventually start to occur, especially if conditions are acidic.There are two primary techniques which can be used...
304 Stainless Steel Seamless Pipe processing Fracture Analysis
304 stainless steel seamless pipe blanks by quality, observed macroscopic fracture morphology analysis of the heating system and hot tube perforation occurred in pickling and cold working process, the analysis of the 304 stainless steel seamless pipe processing fracture causes. Noted rational selection process and adherence to the rules will reduce steel processing fracture. It made a number of concrete measures to prevent the occurrence...
Galvanized Features
The appearance of a bluish-white zinc coating, the standard electrode potential is -0.76V, soluble in acid, alkali-soluble, metal music is amphoteric type. Zinc dry air change hardly occurs, corrosion of zinc critical humidity greater than 70%, in the wet atmosphere and therefore can generate a thin film mainly consisting of basic zinc carbonate with carbon dioxide and oxygen effect, this membrane has a certain inhibition and so on, and zinc...
