Q:Heat transfer through steel?
yes it is very possible. as what our teacher in physics said that steel is a good conductor of heat..
Q:Is Grade A Surgical Steel...?
Perfect! 3
Q:Steel Making Process?
From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
Q:Quick ... Does fire burn steel?
It can burn it... but not the sort of fire you would find at home... Ive actually done it before in a silversmithing class with a very hot blow torch. It takes a long time, the metal first goes pink, then glowing orange red... it stays that way for a while, and then 'cracks' kind of loudly and basically disintergrates very suddenly. A torch this hot has a very hard (noisy) flame which is very transparent. But you cant burn it in the fireplace.
Q:What is Mild Steel? Is it the same as Seamless Steel?
iron mild steel are not the same but you need iron to make mild steel this is done by the process off a blast furnace were iron ore coke limestone are added coke is coal which has been put into a coking oven to remove some impurities then once the coke, iron ore limestone are mixed this and comes out the bottom of the blast furnace red hot is know as pure iron once you have this you then put it into the BOS Basic Oxygen Steel making were pure oxygen is blown onto the the iron for about 45 min which then turns the iron into steel. hope this helps :o)
Q:What are the components of Stainless Steel?

Q:is stainless steel and surgical steel the same?
There are hundreds of different grades of stainless steel. Jewelery used for piercings should be made of implant grade. Note that the term surgical steel is not a technical term. It doesn't mean anything, although it sometimes refers to what is technically implant grade stainless. Implant grade stainless steel must conform to the ASTM standard 316LVM F-138-00, otherwise the seller cannot call it implant grade. This is something you should always ask about specifically. Are your stainless items F-138-00 compliant? Jewelry that only claims to be stainless isn't good enough. Jewelery sold in mall stands are typically nickel plated, bargain-basement low grade stainless. Allergies to nickel are common.......BUT there is a big difference between allergies, and infections. Infections are caused by bacteria, not by the metal itself, and if you're getting infections it's a sign you're not keeping the piercing clean and sanitary. Simply switching to a different metal won't prevent infections from recurring. To prevent infections you need to take steps to keep new piercing clean and sanitary. the best way to do this is rinse with 50:50 hydrogen peroxide and water daily, then apply some neosporin. hope this helps.
Q:How much is obselete steel worth when sold as scrap?
Right now, steel is worth $150/ton. Who purchase it? Well, not every scrap yard handle steel, you have to call them up, or look at the company name that has the word steel or iron. But price can vary from each scrap yard. Try to call around. As for someone to pick it up, the scrap yard will mostly charge you a trucking fee and then the price for steel would be lower. But here is another bad thing if you have it pick up. I know some scrap yard are bad...reall bad..they will skim off some weight...a 1k lbs to 2k lbs. Wish you good luck!
Q:Which is a greener building material, steel or wood?
Of course wood+1
Q:8cr13mov steel thoughts?
8Cr13MoV is a decent blade steel...not a great steel, but about as good as you will generally find without paying much higher prices. It's used by a number of well known knife makers... It's basically equivalent to AUS-8 and will work and hold an edge reasonably well for most basic cutting chores. *************************************** From Wikipedia, the free encyclopedia: 8Cr13MoV, a Chinese stainless steel tempered at the Rc56 to Rc58 range and used in the Tenacious, Persistence, Ambitious, Resilience, Grasshopper, Kiwi3 and Byrd lines of knives. Often compared to AUS-8, but with slightly more Carbon.
