Q:I need help! Please help, I'm in Chemistry, and me and my friend Lucy are making a presentation on steel and iron, so how is steel manufactured? Thank you. :D

The steel consists of ( Iron ) and another matter... but the popular one is iron+carbon / iron+silver - When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. Approximately 96% of steel is continuously cast, while only 4% is produced as cast steel ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steel's final rolling it is heat treated for strength, however this is relatively rare.

Q:Where can a find a steel scrubber. Its great to clean cooking vessels. Would be great if someone gives me an idea. I did not find it at CVS, but was in a hurry, will try again tomorrow.

they sell something like what you are talking about at grocery stores called a chore boy. They are where they see sos pads and sponges.

Q:How would you calculate the maximum plastic deformation (expansion) a steel pipe can handle before it actually fails?

You can calculate the maximum reversible strain, for elastic loading as follows: You need to look up the yield strength (for that particular type of steel). Divide this yield strength by the elastic modulus of steel (also called Young's modulus). That gives you the strain at the onset of yielding, the maximum you can strain the steel fibers before crossing the point of no return. If you are interested in the strain until failure, you need to take tensile test measurements. Seldom do people document an equation to model the non-elastic portion of the stress-strain curve of the specimen, because seldom do we design systems to operate with materials which yield. We want systems which only deform reversibly and elastically. This means you need to perform an experiment to find what you are actually desiring to know.

Q:and also what makes different hardness of stainless steel?

a little clarification. steel doesn't become stainless. There are many different types of steel, which is an alloy of iron and other element. The other elements determine things like hardness, corrosion resistance, etc. One element is chromium, which when added in the correct proportions, forms stainless steel. PS, there are many many different stainless steels, with different proportions.

Q:is stainless steel a good steel for sensitive skin? or does it have to be surgical or sterling silver?

idk about sensitive skin but i have stainless steal in i think right now. im sure any are good for a healed belly piercing, if it hasnt been 3 monthes yet then id stick with a surgical

Q:What are the different steel coil specifications?

There are several different steel coil specifications available, including dimensions, thickness, width, and weight. These specifications vary depending on the specific application and industry requirements. Additionally, steel coils can be classified based on their surface finish, such as hot-rolled, cold-rolled, or galvanized.

Q:How are steel coils used in the production of solar panels?

Steel coils are used in the production of solar panels as a crucial component for the frame and support structure. The coils are shaped and cut to size, providing the necessary strength and stability to hold the solar cells and other components securely in place.

Q:What are the common certifications required for steel coils?

The common certifications required for steel coils depend on the specific industry and application of the coils. However, there are several widely recognized certifications that are commonly required. 1. ISO 9001: This certification ensures that the manufacturer has implemented a quality management system that meets international standards. It verifies that the manufacturer has the necessary processes and controls in place to consistently produce high-quality steel coils. 2. ISO 14001: This certification focuses on environmental management systems. It ensures that the manufacturer is committed to minimizing its environmental impact and reducing waste in the production process. 3. ISO 45001: This certification pertains to occupational health and safety management systems. It ensures that the manufacturer has implemented measures to protect the health and safety of its employees and stakeholders. 4. ASTM International Standards: The American Society for Testing and Materials (ASTM) has established various standards for steel coils. These standards cover aspects such as chemical composition, mechanical properties, and dimensional tolerances. Compliance with these standards ensures that the coils meet the specified requirements and are suitable for their intended use. 5. EN Standards: The European Committee for Standardization (CEN) has developed a set of standards for steel coils, known as EN standards. These standards cover similar aspects as ASTM standards but are specific to the European market. 6. JIS Standards: The Japanese Industrial Standards (JIS) are widely used in the steel industry in Japan and other countries in Asia. Compliance with JIS standards ensures that the coils meet the specific requirements of the Japanese market. 7. Product-specific certifications: Depending on the application of the steel coils, additional certifications may be required. For example, if the coils are intended for automotive use, certifications such as ISO/TS 16949 (Quality Management Systems for the Automotive Industry) may be necessary. It is important to note that the specific certifications required may vary depending on the region, industry, and customer requirements. Manufacturers should consult with their customers and industry standards organizations to determine the exact certifications necessary for their steel coils.

Q:The steel is orangish in colour and is mostly made of copper

Steel is an alloy of iron and carbon and optionally one or more of numerous other materials. Copper is normally not used, except sometimes in small percentages. Steel is never yellow or orange in color. Reactivity of steel depends on the materials it is alloyed with. Chromium and nickel with steel make stainless steel, which is much less prone to reactive than iron. .
