4. Stainless steel conservation

Stainless steel is a popular metal for appliances these days. Many kitchen appliances, both large and small, are made with stainless steel. Pots and pans and eating utensils are also made with stainless steel. One advantage of stainless steel is that is very resistant to rusting. But it can get rust stains from transference of rusty objects. You can keep stainless steel rust-free by following a few simple steps.

  1. Clean frequently with a cleaner and water. Any cleaner that is safe for glass is usually safe for stainless steel.

  2. Scrub off all rust from these objects with a scrubbing pad or steel wood pad. This means getting rid of rust from pots and pans before putting them into a stainless steel sink or on top of a stainless steel stove.

  3. Put a rubber mat at the bottom of the stainless steel sink before placing rusted pots and pans (such as cast iron cookware) in the sink.

  4. Apply a thin layer of lubricant (such as mineral oil) to the surface of the stainless steel. This prevents rust from forming.

  5. Inspect equipment frequently, if you notice discoloration, tarnish or water stains, increase the frequency of your fresh water rinses to reduce accumulated chemicals

Q:Classification, advantages and disadvantages of stainless steel welding
Metal gas shielded arc welding.It belongs to the gas protection welding, also is a kind of arc welding, that is, in the protection of gas, welding rod arc melting. Metal gas welding can be used in steel, non alloy steel, low-alloy steel and high alloy, etc. these materials are widely used. But one thing, its protective gas must be an active gas, such as carbon dioxide or a mixture of gases. The only drawback is that if the outdoor welding, then the workpiece can not be damp, otherwise it will affect the protection of gas protection effect.
Q:Why is stainless steel magnetic?
304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. Like a lot of steel strips, the product is made up of 103 tubes, without obvious magnetic induction, producing 9.5 tubes. Due to the large deformation of the Ling bend, the magnetic sense is obvious, and the square tube produced by the utility model has larger deformation than the round tube, especially the folding part, the deformation is more intense, and the magnetism is more obvious. In order to completely eliminate the magnetic properties of the 304 steel caused by the above reasons, the stable austenite structure can be recovered by the solution treatment at high temperature so as to eliminate the magnetism. In particular, magnetic because it causes 304 stainless steel, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic steel 304 always showed a weak magnetic.
Q:The difference between stainless steel pipe and stainless steel composite pipe
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Stainless steel pipes can not be less than the amount of chromium
304 stainless steel tube as 304 steel pipe, in the dry clean atmosphere, have absolutely excellent anti-corrosion ability, but it will be moved to the beach area, with large amounts of sea salt fog, will rust quickly; and the good performance of 316 steel pipe. Therefore, it is not any kind of stainless steel, capable of corrosion and rust in any environment. Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded. Many of the surface damage form, more common in daily life are as follows: 1. stainless steel surface deposited dust or heterogeneous metal particles containing other metal elements of the attachment, in the humid air, condensed water and adhesion between the stainless steel, the two together into a micro battery, cause the electrochemical reaction, the film has been destroyed, called electrochemical corrosion. 2. stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), oxygen in the water under the circumstances, a long time, organic acid, organic acid on the surface of metal corrosion. 3., stainless steel surface adhesion contains acid, alkali and salt substances (such as decoration wall caustic soda, lime water splash), causing local corrosion. 4., in polluted air (such as containing large amounts of sulfide, carbon dioxide and nitrogen oxides in the atmosphere), in case of condensation water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
Q:Why does the 304 stainless steel pipe leak?
The corrosion resistance of stainless steel is due to the formation of a very thin, adhesive and semi transparent chromium oxide film on the surface of stainless steel. Once this layer of film is destroyed, the chromium in the steel react with oxygen in the atmosphere to recover the film quickly, and mechanical damage can quickly produce a protective film. However, if the chemical erosion by ions, especially chloride ions, will quickly dissolve and corrosion, the result is that the metal surface needle or point, there is a certain depth of small holes, this corrosion is called pitting.
Q:What does "stainless steel pipe 201304" mean?
201 stainless steel has a certain acid, alkali resistance, high density, polishing, no bubbles, no pinhole and other features, is the production of various watchcase, strap, cover, high-quality materials. Mainly used for decorative pipes, industrial pipes, and some shallow stretch products. The product belongs to high manganese, low nickel stainless steel, nickel content is low, poor corrosion resistance, in all kinds of desktop, countertops, kitchenware, and outdoor decoration projects and urban decoration industry and high-end household products, a larger amount.
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
Ring type stainless steel pipe connecting end design section of successive and sealing section shape was stepped through the hydraulic tool connection exerts a pressure on the radial deformation of the pipe, stable and sealed sections of Zuohuan extruded and its circumference concave, concave section into which the pipe with forced recess annular snap fastener
Q:What's the difference between cold drawn steel tube and hot rolled steel tube?
Cold drawn steel tubes are produced by drawing, extruding, piercing and the like. The whole steel pipe has no seams. It's a round, square, rectangular steel with a hollow cross section without any seams. It is made of steel ingot or solid pipe blank by piercing and then made by cold casting.
Q:Disadvantages of stainless steel tubes
A more traditional but more expensive pipeline material, durable and more convenient construction. Copper is the first choice in many imported bathroom products. Price is the most important reason for its use, in addition, copper corrosion is also a factor.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean?
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
