Prepainted Galvanized Steel

With galvanized steel as base metal, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.

Q:Stainless steel water bottle? ?
Should be OK- that's reputable vendor. Suggest initial flush insides with very mild acid (fill ~20% with mild vinegar, Pepsi, etc., then shake 1 minute) then rinse 2 times, then look inside to confirm it looks clean.
Q:Ways to damage steel?
There are plenty of ways to damage/weaken steel... shear or tensile force, fatigue, temperature, corrosion, grinding, etc... there are even dozens of ways to do each of the things I just listed. But in the case you suggested, with the steel being very close to skin... a simple pair of bolt cutters would probably be the easiest.
Q:What is better carbon steel or stainless steel for a knife?
It depends on what your husband plans to do with the knife. In general, stainless steel knives are more resistant to rust and corrosion but carbon steel knives hold a sharp edge for longer. Those are only general statements, because high carbon knives can be coated to resist rust, and some high quality stainless steel knives can hold a great edge. There are many different metal alloys used for knives, and each one has its own properties. If I were you, I would buy a high carbon steel knife, unless you think your husband would use the knife under conditions that might make it rust (fishing or boating, for example).
Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:quality of steel ..................!!?
The quality of the alloy can be very well be judged by its appearance and lustrous surface. The more luster on the surface the more refine will the steel be. To judge its tenacity and endurance, the alloy can be subjected to a series of procedures involving stress and shock. There are many more scientific methods of measuring the quality of the alloy such as texture measurement technique etc are also employed. In layman’s term the quality can be measured by the hardness of surface, brightness and smoothness of the surface and absence of any depressions or troughs.
Q:why would you clean metal with steel wood?
Steel wool is a mild abrasive. I don't know what it is you are cleaning, but it is probably to remove any coating or oxidisation from the metal. Maybe you are using a metal for an electrode (perhaps a steel nail pushed into a lemon?).
Q:Steel EASY 10 POINTS!?
steel is used for cars and trains. one of the largest steel manufacturers is in my town its called CarTech its in reading pa.
Q:Stainless steel?
The nickel and chromium content do have some effect on shine. But mostly they effect the corrosive and rust resistance property's of the stainless steel. 300 series stainless steel such as 304e or 316e will not rust like 400 series 416e eventually will. All types of stainless steel can achieve a bright shine. The key is using jewelers rouge and the correct buffing wheel. Avoid scotchbrite if you want shine. It will clean your stainless steel but it will not shine it the way you want. Miketyson26 (certified tig welder)
Q:What minerals are mixed to make steel?
It depends on the type of steel that you want. For example- A cold drawn carbon steel spring wire consists of Carbon,Silicon,Manganese,sulphur potassium. If you want to make an alloy steel you can also add chrome,vanadium , nickel etc. It depends on the combinations and percentages of each used.
Q:what is a better grade of steel?
SAE 440 is the best. Classified as high grade cutlery steel. There are various grades of 440: A, B, C, and F. 440 A is the most stain resistant while 440 C has the most carbon and can achieve the highest hardness (Best edge Retention). SAE 440 Chemistry: 16 - 18% Chromium, 0.60 - 1.2% Carbon, 0.75% Molybdenum. SAE 420 is pretty good. Classified as cutlery steel, it is a stain resistant grade but has less chromium and significantly less carbon than SAE 440. SAE 420 Chemistry: 12 - 14% Chromium, 0.15% Carbon (min), 0 Molybdenum Chromium is what makes the steel corrosion resistant. It also adds toughness. Molybdenum adds extra corrosion resistance and adds hardenability. So you can see by chemical components that 440 is highest quality although that also means more cost. 1045 and 1065 are low quality steels and you should probably never use them for a knife. The 1 indicates plain carbon steel with little other alloying elements. The last two digits indicate how much carbon is in the steel. 1045 has 0.45% carbon, mid-range hardenability. 1065 has 0.65% carbon, high hardenability. So if I had to choose I would choose 1065 over 1045 but the difference isn't that noticeable. Everything I said here assumes they have all had the optimum Quench and Temper heat-treatment for their chemistry grade.
