Q: did bible stated that steel is coming from outer space. i mean meteor rocks that enter our earth sistem contains the minerals iron.: If you are using either an NAB or RSV translation of the Bible, steel is only mentioned once in the Bible. Compare Nahum 2:4 (NAB) and Sirach 31:26 (RSV). There is no reference of an outer space in the Bible. Furnace is mentioned in Sirach. It takes a lot of energy to mix Iron and Carbon to produce steel. The alloy can only be produced in the furnace at an extremely high temperature.

Q: The stainless steel drinking fountain had a little acid on it and rusted. I need to restore it. Is this possible?: Stainless steel doesn't rust, whatever acid you got on it was some pretty bad stuff to make a reaction like that, you can try sanding down past the reaction point and polish it out but that's about it, that or it wasn't stainless to begin with. if its brushed chrome to simulate stainless it would have to be replated, not cheap. and probably not worth it

Q: How are steel coils used in the production of electrical appliances?: Steel coils are used in the production of electrical appliances as the core component for electromagnets. These coils are wound around a metal core and when an electric current passes through them, they create a magnetic field which is essential for the functioning of various electrical components such as motors, transformers, and solenoids.

Q: Can steel coils be painted?: Yes, steel coils can be painted. Painting steel coils is a common practice to enhance their appearance, protect them from corrosion, and provide additional durability. The coils are typically cleaned, prepped, and coated with a primer before applying the desired paint color.

Q: I want to save water $$, so I want to use frozen steel to cool my coke. possible or no?: Hey man, don't you think it would save more $$$ to cool your coke in the fridge than trying to cool steel? How do you plan on cooling the steel? And you can't freeze steel but you can make it cold. You are just joking right, I hope so anyway?

Q: How long do steel coils last?: The durability of steel coils can differ based on different elements, including the steel's quality, the storage or usage conditions, and the specific application. Typically, top-notch steel coils can endure for numerous years or even decades before exhibiting any signs of deterioration or wear. Nevertheless, it is essential to acknowledge that if steel coils are not adequately maintained or shielded from moisture or harsh surroundings, they can be prone to corrosion. Consequently, consistent inspection, maintenance, and appropriate storage or usage methods play a pivotal role in optimizing the lifespan of steel coils.

Q: In pounds per square inch what is the tensile strength of strong steel?: Depends on what you mean by strong steel. Typically the ultimate strength/yield point of steel used for building structures (beams, columns, joists, plates) is in the range of 36,000 to 50,000 psi. The strength is specified by the designer (in the U.S.) by its ASTM designation. e.g. ASTM A36, A572, A500, A307, A325 ... A36 is typical mild steel, A572 Grade 50 (50,000 psi) is often called high-strength Really high strength steels such as pre-stressing strand can have ultimate strengths more than 10 times these values.

Q: What are the different types of steel coil slitting blades?: Different types of steel coil slitting blades are available to suit specific applications and materials. The following are some commonly used types: 1. Circular slitting blades: These blades, which are circular in shape, are widely used for slitting steel coils. They have a sharp edge that cuts through the coil as it rotates. The choice of material for circular slitting blades, such as high-speed steel or tungsten carbide, depends on the desired cutting performance and durability. 2. Arbors: Arbors are cylindrical blades used in conjunction with circular slitting blades. They hold the circular blade in place, allowing for precise and consistent slitting of the coil. 3. Shear slitting blades: These blades are used for cutting thicker and harder materials like stainless steel or aluminum. They have a straight edge and work by shearing the material apart, rather than cutting through it like circular blades. Shear slitting blades are typically made from high-quality tool steel to withstand the high forces involved in cutting thicker materials. 4. Crush cut slitting blades: Crush cut blades are suitable for slitting softer materials like paper or plastic. They have a blunt edge that crushes and tears the material instead of cutting it cleanly. Crush cut blades are often made from materials like carbon steel or hardened stainless steel. 5. Razor slitting blades: Razor slitting blades are ideal for slitting delicate materials that require a clean and precise cut, such as thin films or foils. They have an extremely sharp edge that slices through the material without causing any damage or distortion. Razor slitting blades are typically made from high-quality stainless steel or tungsten carbide. Choosing the right type of steel coil slitting blade is crucial and depends on factors such as the specific application, material, and desired cutting performance. The blade selection significantly affects the quality and efficiency of the slitting process.

Q: I know that carbon steels and alloy steels are different but are carbon steels still alloys?Thanks!: Carbon steel, or plain-carbon steel, is a metal alloy. It is a combination of two elements, iron and carbon. Depending upon the amount of presence of carbon in the alloy, Carbon steel can be classified into 4 different categories- Low Carbon Steel Medium Carbon Steel High Carbon Steel Very High Carbon Steel
