Q:Question about steel type used in bridges.?
It is used for other things besides bridges and that might be a bad use. Corten was used for very tall light standards in the Fort Worth Water Gardens with the clear understanding that it was to be kept dry. As time passed and personnel changed, somebody decided the round base with bolts sticking up was ugly and put dirt and plantings in the basin in the concrete holding the poles. The watering of the plants kept the rust going through the steel and one pole eventually fell, killing two people. The other light poles were removed.
Q:WHAT ARE THE WAYS THAT YO COULD PREVENT STEEL FROM RUSTING WHEN IT IS EXPOSED TO WATER? SALT WATER? VINEGAR?
rust is oxidation . remove contact with O2 , it wont rust . you can place it in a oxygen free atmosphere , you could plate it with zinc or chrome , you can use a lead based paint .
Q:What’s the quality of SUS434 Stainless Steel from Jinsong Stainless Steel?
JinSong SUS420J2 stainless-metallic/ X30Cr13 has larger intensity, hardness and hardenability than 12Cr13 metallic and 20Cr13 metallic after quenching. It has much less corrosion resistance to dilute nitric acid and vulnerable organic and organic acid than 12Cr13 metallic and 20Cr13 metallic in room temperature. you will get extra strategies on its good website**
Q:difference between metal and steel?
well, steel is a type of metal. It's sort of like asking the difference between a bug and an ant, an ant is a bug, but not every bug is an ant. Likewise, steel is metal, but not all metal is steel. Gold is metal, Silver is metal, Iron is metal, Steel is metal.
Q:Is stainless steel good for a butterfly knife?
This isn't really a question for this section, but I'm still happy to help out since I'm a big cutlery nerd as well. One thing to look out for when buying a knife is a lack of specifics on what steel is being used. High Carbon Stainless Steel doesn't tell you what the steel is, just what it MIGHT be. Chances are it's something along the lines of 420HC or 440A, both of which are softer steels. They aren't the worst steels around, but they are very quick to dull. You'd be better off looking at the Balisongs of Benchmade. They'll cost more, but you'll know that you're getting something made with quality materials and that won't break on you. And if it does break for some odd reason, Benchmade's warranty and customer service are both fantastic. Although if a more questionable knife is okay with you as long as the price isn't too high, then at least 420HC and 440A aren't too brittle and will take a decent edge even though they'll dull quickly. As for whether stainless steel is good for a knife or not, that depends on the type of stainless steel and what you're going to use the knife for. Many stainless steels are more brittle than a carbon steel, so high carbon stainless steels are a bit more likely to rust but a little tougher as well. In a butterfly knife, a steel like that is a good way to go, although the steels used by Benchmade, as I mentioned, are of a much better quality.
Q:A roll of 1 meters wide color steel roll about how many tons?
Generally speaking, it will be about 4 tons, the export may be larger, but 10 tons of papers have not yet seen
Q:Does mild steel have a high carbon content?
Steel is defined as an alloy of iron and carbon (often supplemented by further materials) with a carbon content between 0.01 % and 2.06 %. 4% is in the realm of cast iron, which isn't quite as rigid as steel. Mild steel contains 0.16 - 0.29% carbon. You're off by more then a decimal.
Q:Alumnium Vs. Steel?
i also have a gsx-r1000 06.. always change the sprockets and chain at the same time if you don't it will just wear out the chain faster. all you really need is to go down 1 on the front sprocket and 2 up on the back. stick with the steel sprockets they will save you money in the long run. if you like to wheelie all the time stay away from the aluminum it will wear out quicker.. they also make sprockets that are aluminum on the inside and steel on the outside.
Q:What is the best butcher's steel?
get one made in germany if you can. you might want to invest in some stones. they have some great videos on youtube on how to sharpen knives.
Q:Fire resistant steel?
In the fire protection world, we do not consider steel fire resistant. Of course it doesn't burn under ordinary conditions, but it lose strength as it is heated. As has been mentioned, there are coatings which insulate steel to enable it to withstand high ambient temperatures for a long time. Construction using this method is called fire resistive construction.
