Q: I don't know why but I'm having a VERY difficult time finding the melting point of 1008 steel.: 1. okorder 2. Input (melting point 1008 steel) as the search string 3. Check the links; the third one showed the answer in an MSDS

Q: What are the main factors that affect the formability of steel coils?: The main factors that affect the formability of steel coils are the composition and microstructure of the steel, the thickness and width of the coil, the temperature during forming, and the mechanical properties of the steel.

Q: how is stainless steel made? what are the things used in making it?: There are 3 basic stainless steels. The Martinsitic, the ferritic, and the Austinistic. The spelling may be wrong on all of them. (Got out of school in 1966 with my metallurgy in 1965. The Ferritic is magnetic and has some resistance to corrosion but the Martinsitic is much more resistant to corrosion. The Austinitic stainless is very resistant to corrosion. The differences are the amount of Chrome and Nickel in the batches. The Austinitic has an 18/8 ratio of Chromium and Nickel with the rest Iron and minor ingredients. The carbon content is very important and these steels are often made in small batches with close monitoring of composition and carbon content. Scrap metals are frequently used with the chrome and nickel being added as carefully selected scrap or even fresh crude stocks. Electric melting is frequent to avoid contamination.

Q: I have a need to connect various stainless steel tubes and fitting together and was wondering how to do it. I know a TIG welder is an option but have heard rumors that there is a way to solder it in much the same way you affix copper pipe. Perhaps with higher heat and different flux. I need step by step and maybe suppliers of the materials. Thanks in advance and please I do not need the call a plumber answers as I've gotten in the past: ss has to be either welded or brazed you can [solder ] it but it has to be a silver solder, and will not have any strength

Q: How are steel coils processed into finished products?: Steel coils are processed into finished products through a series of steps, including flattening, cutting, shaping, and treating. First, the coils are unrolled and flattened to obtain a flat sheet. Then, they are cut into desired lengths and shapes using various cutting techniques. Next, the sheets are shaped into specific forms using methods like bending, rolling, or stamping. Finally, the finished products undergo treatments such as heat treatment, galvanization, or coating to enhance their durability and appearance.

Q: When I got my AR-15 I was told that I should get either get Brass or Steel Case ammo and stick with one or the other, I was wondering why? It surely wouldn't damage anything switching back and forth between the two would it? I got steel case ammo and I have stuck with It and probably will either way, I was just wanting to know it I ever wanted to get some Hornady's or somthing like that.: Steel cases won't hurt your AR, they just don't expand to seal the chamber as well as brass cases, causing increased fouling of the chamber that leads to failures to extract. If you use steel cased, clean well, and use a chamber brush. You can switch back and forth without harm.

Q: Please explain why steel is denser than wood.: Steel is basically a mixture (not the compound) of iron and carbon. Iron, by itself is an element and so is carbon. The atoms of Iron are larger in size compared to carbon. All the atoms of all the elements, smaller or larger, are spherical. If naturally a solid, the atoms of all such elements have voids as their atoms are closely packed. You can imagine a basket of oranges; you could see that void or empty space (which I am speaking about) between four or more of the oranges put together. Now, when heated to more than about 1500 degrees celcius, Iron melts and atoms in molten form increase space between themselves. Raising the teperature to 1800 degree celcius, carbon is mixed with iron. At this stage it causes the spherical carbon atoms to fill in the spaces present amongst the spherical atoms of the iron. On cooling, already dense iron becomes denser because no space is left there between its atoms. This denser form of iron + carbon has become steel in which carbon is not more than 3 to 4% of the total volume. Wood is nothing but a fallen and dried tree's part. When green and alive, tree's stem and branches have pores in there texture, which are fillled with water and other biological fluids necessary for the life of the plant. When dried all the fluids, especially water gets evaporated. and the pore are empty now. The term Density, means mass divided by volume (kg / cubic meters). Iron + Carbon (the steel) so tightly packed and Iron having very high atomic weight is surely denser than wood with just carbon and a few other elements with no significant role to play in the mass calculation; particularly if their are empty pore spaces filled with air only. Imagine the mass (which common people mistakingly call the weight) in kilograms of a peice of steel with dimensions of 1 meter cube and imagine the same for the dried wood. What do you think---which one is denser?

Q: What are the safety regulations for steel coil production facilities?: The safety regulations for steel coil production facilities differ depending on the specific country or region. However, these facilities typically implement some common safety measures. One primary safety regulation is the proper training and education of employees. All workers in steel coil production facilities must undergo training on potential hazards and the correct safety procedures to follow. This includes training on handling heavy machinery, operating cranes or forklifts, and understanding the risks associated with working in a high-temperature environment. Maintenance and inspection of equipment are also important safety regulations. Regular inspections should be carried out to ensure that machinery and equipment are in good working condition and do not pose any safety risks. Moreover, maintenance procedures should be implemented to promptly address any issues or malfunctions. Fire safety is a crucial aspect of safety regulations in steel coil production facilities. Fire prevention measures like fire alarms, sprinkler systems, and fire extinguishers should be installed. Regular fire drills should also be conducted to ensure that all employees are familiar with evacuation procedures and can respond swiftly and effectively in case of a fire emergency. The use of personal protective equipment (PPE) is another vital safety requirement in steel coil production facilities. Employees must be provided with appropriate PPE such as safety glasses, helmets, gloves, and steel-toed boots to protect them from potential hazards like falling objects, sharp edges, and high temperatures. Additionally, safety regulations often necessitate the implementation of safety barriers and guards around machinery and equipment to prevent accidents and injuries. This includes safety gates, railings, and protective covers that restrict access to hazardous areas and prevent unauthorized entry. Regular safety audits and inspections should be conducted by relevant authorities or safety professionals to ensure compliance with safety regulations. Companies should also foster a culture of safety by encouraging open communication about safety concerns, providing safety training and refresher courses, and rewarding employees for adhering to safety protocols. It is important to note that safety regulations may vary across jurisdictions, and it is advisable to consult the specific regulations applicable in the country or region where the steel coil production facility is located.
