Q:Are there different types of steel that are used in construction of beach houses that withstand corrosion?
there is a weathering steel that corrodes and then stops. The outer surface of the steel is a rusty looking brown but after the first layer of rust appears, the process stops. It used to be called A588 steel. So called mild steel is not A36 anymore, it is A992 (50 ksi yield). The only material that is A36 anymore are angles, channels, and plate. You can coat the steel with an epoxy coating to protect the steel from this highly corrosive environment. Google a company called TNEMEC. They offer epoxy coatings for steel and other coatings. Weathering steel and epoxy coating are not cheap options.
Q:What is better carbon steel or stainless steel for a knife?
carbon steel is my choice. googlecarbon steel vs stainless steel knives for more info. If you buy stainless make sure it is an alloy that will hold an edge..many a shiny knife is just a dull dud. Carbon blades don't rust unless they are left laying in the wet. I was having this conversation with a Friend once. So I took his knife and struck his knifes edge against mine with a light blow.. His had a 1/16 dent in it, mine not even a mark on it. I assume this is not a kitchen knife.
Q:How to weld stainless steel?
Stainless steel is a fascinating metal to weld. Welding stainless can be difficult if you don't know what you are doing. It reacts to excessive heat by warping and distorting once it cools. Everything shows up in stainless. If you weld with too much heat you can see it by the heat marks left in the metal along with any distortion. It also scratches very easily so you must take care when welding on a metal table. Stainless steels can be welded using several different procedures such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding but stainless steel welding wires have been developed for welding stainless steels.
Q:Steel I-beam for header?
Probably the reason some contractors don't like this idea is that your new built-up beam, being only 6 tall, is not going to allow the joists above to attach effectively. The triple microlam with steel plates is sooooooo overkill in strength, but doesn't have the height to allow the floor joists to proberly attach. Your span is not so great that a built-up beam wouldn't work great. Assuming that your second floor joists are 2 x 10, I would use 2- 2 x 10 with 1/2 plywood sandwiched between. This is all that you really need.
Q:Is steel industry good for investing currently ?
I feel metal stocks can give some return now if you invest.
Q:Steel frames are completely out of the game...?
Ah, I took a nice 40mi spin on my steel road bike today. Maybe it's not as fast as my other rides...I don't know, I'm too busy enjoying the ride. Steel is timeless.
Q:Steel pipe info please...?
you can search for some web which sells steel pipe and other relative products to know more details.
Q:Why nickel makes stainless steel non-magnetic when nickel itself is ferromagnetic?
All stainless steel is non magnetic.
Q:keeping a stainless steel stove clean and shiney?
A kitchen range finished in stainless steel looks professional and clean. Stainless steel stove requires a bit more cleaning than a traditional stove. Use an oil based product. Baby oil or WD40 are the products of choice for many people. You don’t want to put the oil directly onto the appliance, instead just pour some onto the cloth and wipe down the appliance. Routine maintenance on your stainless steel stove is the best way to keep the surface steel clean as well as scratch free.
Q:Which Material is Better? Glulam or Steel?
Glulam. Cheaper to buy, cheaper to install. Takes up less space than an I-beam.
