Q:Why low carbon steel have poor magnetic properties?
The composition of the steel is almost tertiary to many other considerations, except that there are certain elements and percentages of elements which tend to affect the crystaline structure in the steel. The most basic question is whether the crystaline arrangement of atoms in the steel is martensitic or austenitic, and many factors influence that. In general, martensitic structure is magnetic and austenitic structure doesn't respond much to magnetic fields, but there are varying degrees of martensitic and austenitic -- there is never a pure state. Read the articles at bottom.
Q:dangers of the steel factories?
Same as other steel plants, getting crushed by falling steel, getting burned by hot metal etc
Q:how strong is 440 stainless steel?
You can probably Google the strength properties for 440. The question your question asks is, Why?
Q:What type of welding rod to use welding cast steel?
I Use these for cast iron, www.yms.co.uk/welding-rod-small-pack/2.5mm-cast-iron-welding-rod-small-pack/1951/11612/detail.asp they are expensive when compared to welding rods for steel but i find that normal steel ones dont work on cast iron
Q:steel or graphite?
If its for your bf, i would buy steel. Most guys prefer steel because it is more accurate and it think every guy on the pga tour uses steel shafted irons. Steel also usually costs less, which helps. Neither one is better, its just a matter of personal preference.
Q:Long term effects of steel on skin?
Stainless steel contains both nickel and chromium. These two alloys are responsible for most of contact dermatitis in people. Some of my co-workers making steel had such bad reactions to chromium that they had to quit their jobs. Their skin was always inflamed. People don't react to finished stainless steel the same way because the alloys are bonded tightly in the heat treating process. But if you are grinding it and getting the dust on your skin, you could get a contact dermatitis if you are sensitive. I don't think it would absorb into your blood stream or do any long term damage to your skin. If you do get a reaction, you would have to cease your exposure or in a worse case scenario risk getting a body wide reaction like my coworkers. I would not worry about any exposure making rings out of stainless steel. After all, stainless steel is used in sugical implants and most people are fine.
Q:Can fire resistant building materials burn hot enough to melt steel columns?
Steel loses strength as it is heated and will fail long before it melts. A mild steel that starts out at 100 degs F with an allowable stress level of 20,000 psi will be down to only about 2000 psi at 1000 degrees. As to fireproofing for steel. It doesn't have an unlimited life. In fact most has only a 2 to 4 hour rating and that is determined in ideal conditions in a laboratory. The idea is to give firefighters time to get everyone out of the buidling.
Q:mechanical behaviour data for recycled steel?
It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.
Q:Fire resistant steel?
There is a chemical that is used presently that is sprayed onto steel beams called Monocoat. Its a form of insulation that gives steel protection for up to 2 hours I think. Hope that helps!
Q:Is instant steel-cut oatmeal less healthy/nutritious than traditionally cooked stove-top steel-cut?
Most people who are used to rolled oats have a very hard time adjusting to steel cut oats that are cooked only 30 minutes. For many, it's not much different than eating them raw. (Raw, soaked oats is called cram. Having to eat uncooked oats, as only the poorest would do, gives us the expression 'to cram it down your throat'.) Better still is to cook them thoroughly at night then reheat portions for breakfast if you're in a hurry. They'll keep about five days at a time under refrigeration. Any small nutritional loss from longer cooking is more than compensated by the better digestibility of well-cooked oats. That is, the nutrition is wasted if the oats pass undigested through the body. For most of us, that would happen. Indeed, we are not cows. Neither are we horses. People need to cook their oats.
