Q:What is the difference between regular steel stainless steel? Why does steel rust but stainless wont? Is stainless some kind of alloy or something? Any knowledgeable input would be great. Thanx!: In metallurgy, stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content by mass. Stainless steel does not stain, corrode or rust as easily as ordinary steel (it stains less), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch straps. Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further corrosion

Q:What are the challenges faced in the recycling of steel coils?: There are several challenges faced in the recycling of steel coils. Firstly, one of the main challenges is the collection and sorting process. Steel coils are often used in large-scale industries and construction projects, making it difficult to collect and transport them for recycling. Additionally, steel coils may be mixed with other materials, such as plastic or wood, which further complicates the sorting process. Another challenge is the size and weight of steel coils. Steel is a heavy material, and coils can be quite large, making it challenging to handle and process them efficiently. Specialized equipment and machinery may be required to move and separate the coils, which can add to the cost and complexity of the recycling process. Furthermore, the quality of steel coils can vary, which can impact their recyclability. Steel coils may have impurities or contaminants, such as oil or paint, which need to be removed before recycling. These impurities can affect the quality and integrity of the recycled steel, making it less desirable for certain applications. Additionally, the energy and resources required for recycling steel coils is a challenge. The recycling process involves melting down the steel, which requires a significant amount of energy. Furthermore, the transportation and processing of steel coils also consume resources and contribute to carbon emissions, making the recycling process less environmentally friendly. Lastly, the market demand for recycled steel coils can fluctuate, which can impact the viability of the recycling industry. The demand for steel products can vary depending on economic conditions and industry trends. This can make it difficult for recyclers to find buyers for their recycled steel coils, potentially leading to stockpiling or disposal challenges. Overall, while recycling steel coils offers environmental benefits and conservation of resources, there are several challenges that need to be addressed to ensure its successful implementation. These challenges include collection and sorting, handling and processing, quality control, energy and resource consumption, as well as market demand.

Q:Steel seems to be much less expensive. What is the reason why? I've heard steel will ruin a barrel after time....is that true? But with the price difference maybe it don't matter? Is steel reliable? What are the negatives about steel I should know before buying?: steel bore - brass copper chrome-lined steel bore - steel is fine. steel jacketed bullets are harder than copper jacketed bullets and would result in higher pressure, more wear in a steel barrel than a chrome-steel barrel. chrome-lined steel is roughly 2X as hard as 4140 steel. even better, nitrated chrome steel is roughly 3-4X harder than 4140 steel. but it s fairly new is a bit pricey. most AR barrels are chrome-lined. you can tell easily if the chamber and bore has a silvery look. regular steel is just black. steel cased rounds are reliable, however plain, uncoated steel cases may feed with some difficulty due to a rougher case finish that results in more friction than the polished, smooth brass cases. cheap ammo (doesn't matter if steel or brass) always shoots more dirty. aside from that I would recommend you try a bit of each of go with whatever shoots most accurate and feeds without problem.

Q:What are the different types of welding used for steel coils?: There are several different types of welding used for steel coils, depending on the specific requirements and applications. Here are some of the most common types of welding techniques used for steel coil fabrication: 1. Shielded Metal Arc Welding (SMAW): Also known as stick welding, it involves the use of a flux-coated electrode and an electric current to create an arc between the electrode and the base material. SMAW is a versatile and widely used welding technique suitable for various steel coil applications. 2. Gas Metal Arc Welding (GMAW): Commonly known as MIG (Metal Inert Gas) welding, GMAW uses a continuous wire electrode and a shielding gas to protect the weld pool from atmospheric contamination. GMAW is known for its high welding speed and ease of automation, making it a popular choice for steel coil manufacturing. 3. Flux-Cored Arc Welding (FCAW): Similar to GMAW, FCAW uses a tubular electrode with flux inside. The flux provides both the shielding gas and additional alloying elements, resulting in increased efficiency and improved weld quality. FCAW is often used in high-speed welding applications for steel coils. 4. Gas Tungsten Arc Welding (GTAW): Also known as TIG (Tungsten Inert Gas) welding, GTAW uses a non-consumable tungsten electrode and an inert gas, typically argon, to shield the weld area. GTAW produces high-quality, precise welds with excellent control over the heat input, making it suitable for thin steel coil materials and critical welding applications. 5. Submerged Arc Welding (SAW): This welding technique involves the use of a continuously fed wire electrode and a granular flux that covers the weld area. The arc is submerged under the flux, providing excellent protection and reducing the need for post-weld cleaning. SAW is commonly used for welding thick steel coils due to its high deposition rates and deep penetration capabilities. These are just a few examples of the different types of welding techniques used for steel coil fabrication. The choice of welding method depends on factors such as the specific steel grade, thickness, desired weld quality, production speed, and cost considerations. It is essential to select the appropriate welding technique to ensure the durability and performance of the steel coils in various applications.

Q:Has anyone painted their appliences with stainless steel paint? I found on the internet what is called Thomas Liquid stainless steel paint. If you have used it for your kitchen appliences or cabinets, how were the results? How hard was it to apply? Would you recommend it?: I am also considering buying Thomas Liquid Steel, but have not used it or seen it used before. I did call a store that sells this product and they said they saw the mfg demo the product at a trade show. The store rep told me that the results were absolutely amazing. I think I will buy the medium kit direct from the mfg for $129 and give it a test run first on something other than my kitchen appliances.
