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:What's the difference between cold drawn steel tube and hot rolled steel tube?
Hot rolling is relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
Arc welding is the most widely used welding method in industrial production, it is to use the principle of arc discharge (commonly known as arc combustion) the heat generated by the electrode and the work piece and the formation of weld in melting each other after condensation, so as to obtain the solid joint welding process. The scope of application of electric arc welding is very extensive, such as bucket teeth of excavator, loader, bulldozer blade blade plate, screw conveyor, crusher, mixer blade, rail, forging, gear wheel flange, all kinds of mold, slag crusher, ball mill, machine tool equipment etc..
Q:What does "stainless steel pipe" DN mean?
In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.
Q:Stainless steel pipe pickling ratio
Usage: used for contaminant removal of various types of stainless steel parts, sheet metal surface and its equipment rust, oxide skin, after welding of yellow blue black spot welding, a silver white metal surface cleaning, and surface passivation, corrosion resistance of stainless steel.
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:What wire is used for welding of 316 stainless steel line?
Inspection of assembly and tack welds;1, check the geometry and shape after assembly, whether it conforms to the provisions of the drawings. :2, assembly and assembly clearance is 1.5 - 2mm, using TIG welding, three point positioning welding,The welding seam position for the clock 3 points, 9 points and 12 points, the welding materials used should be the same as the welding materials, welding length is 10 15mm, welding requirements and guarantee no defect, the wrong side is less than 1.5 2mm.3, the group is not allowed to use strong assembly, the joint wall must be flush.4, when welding, there must be no air, slag, tungsten and crack.
Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
Unless they are not stainless steel, or they control the temperature of the heating tube, the continuous heating will be red, after all, the material has not changed. If the outside of the heating tube is ceramic, it won't be red.
Q:Are stainless steel pipelines buried in need of corrosion protection?
Pipeline buried environment factors: underground laying requirements of 3, one is corrosion protection, two is elevation, slope, and three is density. If it is electrochemical reaction, the design should have technical instructions or preventive measures.
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
Some 25.4 such outer threads, is the imperial Whitworth Thread and American Standard unified thread, single head wire estimate.
Q:How can I clean the stainless steel tube?
1, cleaning stainless steel gently method is simply to use hot water and clean soft cloth to wipe the surface, and then use dry metal with other soft cloth, to prevent water stains thoroughly.2, if ordinary water leaves some dirt or grease, you can add a mild detergent water.
