Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.

The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.


The Usage of Glavanized Steel Coil:


Galvanized steel coil products mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce industries ect.


 (1) In construction industry, hot dip galvanized steel coil is mainly used to manufacture anticorrosion, industrial and civil architecture roof boarding, roof grille, etc.


(2) Light industries use hot dip galvanized steel coil to make home appliance’s case, civil chimney, kitchen utensils, etc.


(3) Auto industry mainly use hot dip galvanized steel coil to produce corrosion resistant parts of cars


(4) Agriculture, animal husbandry, and fishery mainly use hot dip galvanized steel coil for food storage, meat and aquatic products’ freezing and  processing equipment etc;

Q:what happen if carbon steel is exposed to an oxygen?
Blowing oxygen or air rich in oxygen through molten carbon steel is a way of lowering the carbon content. The properties of carbon steel depend very much on the carbon content . too much and it is very brittle. It is all governed by a complex phase diagram. If the steel isn't actually melted, then only insignificant effects at the surface will occur.
Q:Where can I go to find out info about different blade steels online?
White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.
Q:Fireproofing structural steel?
This would depend upon the method of fireproofing. Steel used to be insulated with an asbestos coating. Of course the steel under the insulation had the same critical temperature as the uncoated steel but was protected from external heat by the insulation. More commonly it would be an alloy and there are so many that one could not guess except to say it should be higher than the original.
Q:Casting Stainless Steel?
You have 2 options. Sand casting or investment casting. Stainless steel can be cast with either of these methods. In either case a model or pattern will have to be created. For sand casting the pattern is all that is needed to go to casting. For investment casting the pattern is used to make a wax casting, which is then coated with the investment. The wax is burned out and the metal is then poured into the cavity. If you are making just 1 or 2 pieces you can have waxes machined. This saves the intermediate step Depending on the size machining may still be your best option. Especially if you want just 1 part.
Q:In the warehouse management system of steel coil
Warehouse is an important component of enterprise material supply system. It is also the tache of enterprise material circulation and storage, and it also undertakes many functions of material management. Its main tasks are to keep the stock well, to be accurate, to be of good quality, to ensure safety, to prompt the people, to produce, to be considerate, to reduce costs, and to speed up capital turnover.
Q:Does stainless steel turn brown or bronze?
I would say don't wear it in the shower because it will tarnish and it could rust.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:How difficult is it to harden steel?
Some steel won't 'harden' very much to begin with. Mild steel found commonly around the shop/farm/house has few alloys other than carbon, and may not get the desired hardness no matter what you do. A quick test to see what type you have (mild steel vs. alloy) is to touch it to a grinding wheel.
Q:Heat Resistant Chemical for Steel?
There is, but I don't know what it is made out of. It is probably some fireproof, foam material which acts like insulation. I doubt it is designed to resist abrasion however. Most things which adhere to metal surfaces are not flameproof, and those which do resist fire are not good insulators. For example, the ceramic coating of appliances like stoves and washing machines adhere very well and are fire resistant, but do not insulate. It was the failure of the steel insulation which caused the collapse of the world trade centers. The impact of the airplane tore away all the insulation on the supporting struts of the building and then the fire caused the steel to soften and break. Steel was once insulated by wrapping it in asbestos cloth and then applying plaster over this to form a shell. It did not actually adhere to the steel but it did insulate it, and was fireproof. However asbestos is a cancer hazard and a lot of old buildings are being stripped of their asbestos as a safety precaution. The asbestos can be replaced with fiberglass which is usually duct taped together.
Q:What is the steel industry?
The steel industry is an industry that produces steel. It is one of the largest industries in the world, with China as the leading steel producer
