Quezon1mm201 sDry it in the air below, 1Cr21Ni5Ti, etc. Duplex stainless steel has good weldability, no heat treatment is required after welding,Upington1Cr17Ni2 Stainless steel rod,Upington409 stainless steel plate, and its tendency of intergranular corrosion and stress corrosion is small. However, due to the high Cr content, it is easy to form σ Pay attention when using.
Upington.Surface treatment difference: surface treatment is usually divided into polishing, and the cost is about 1 yuan and 1 meter. If it is thrown into the lens barrel, the cost per ton will increase by 3000 yuan.
This is also one of the reasons why some consumers often encounter oxidation when using stainless steel products. Some consumers do not operate properly in the use and maintenance of products, especially some stainless steel pipe products used in the food and chemical equipment industry
.The oxide scale of stainless steel pipe becomes loose after pretreatment, and then it is easy to remove after pickling. Pretreatment can be divided into the following: alkaline salt melting treatment. The alkaline melt contains 87% hydroxide and 13% salt. The proportion of the two in the molten salt should be strict so that

The back side is not protected by argon, and flux coated welding wire (self shielded flux cored welding wire) + TIG process stainless steel backing welding wire +tig process is adopted. The protection mechanism is that the back weld is protected by the metallurgical reaction between the slag produced by the welding wire melting and its alloy elements. The front weld depends on argon
The fingerprint free processing technology can make the surface gloss of colorful stainless steel more durable and long-lasting, and reduce the time of daily maintenance. At the same time, the stainless steel surface is not easy to stick fingerprints, dust, fine touch,Upington201 stainless steel bar price, I have talked a lot about laser and welding processing. Today I will tell you about stainless steel bending processing. The so-called bending of stainless steel processing workpiece is to fold 2D flat parts into 3D parts. Its processing requires a folding machine and corresponding bending die
Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry.
agent.Argon two processes. The back argon filling protection can be divided into two processes: solid core welding wire +tig process and solid core welding wire +tig+ water-soluble paper process; Back non argon filling protection is also divided into flux cored wire backing welding and welding rod (flux coated wire) backing TIG welding.
It will react with the atmosphere to repair itself, re form this passive film and continue its protective effect.
First of all, let's first understand what stainless steel is. Generally speaking, stainless steel is steel that will not rust. But in the academic sense, steel that can resist the corrosion of weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid resistant steel. In practical application
Change the included angle with the weldment, change the welding speed, etc. to change the temperature of the molten pool, so as to ensure that the weld formation is beautiful (the width is consistent, and there are no concave, convex and other defects); During operation, the current shall be slightly larger than that of solid core welding wire, and the welding handle shall be slightly adjusted to accelerate the separation of molten iron and molten coating
Create brilliance.CO2 welding what does CO2 welding mean? It is a gas shielded arc welding using carbon dioxide as the protective gas, which is fully called carbon dioxide gas shielded arc welding.
In stainless steel processing I have talked a lot about laser and welding processing. Today I will tell you about stainless steel bending processing. The so-called bending of stainless steel processing workpiece is to fold 2D flat parts into 3D parts. Its processing requires a folding machine and corresponding bending die
Products have become a common category in people's daily life.
Upington.Be strict.
Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure, in which ferrite accounts for 5-12%. This dual phase structure is not easy to produce intergranular corrosion.
31317 stainless steel (see the following for the properties of 317 stainless steel) is a kind of stainless steel containing molybdenum. The molybdenum content of 317 stainless steel is slightly higher than that of 316 stainless steel Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steels. Under high temperature conditions when the concentration is lower than 15% and higher than
