A magnet quickly confirmed that this was rich magnetite iron ore. This was the most convenient raw material, and was indeed the material that the ancient Japanese smiths used to create their steel, but I wanted to follow the path my ancestors used in creating the western swords I was fascinated by.

The magnetic response of a piece of steel is a quick and qualitative test that can be useful for sorting grades of stainless steel. Other qualitative tests are listed in Atlas TechNote 1. Austenitic (both 300-Series and 200-series) stainless steels from other steels.

Permanent magnets are made from ferromagnetic materials (cobalt, nickel, iron, neodymium, etc.) To make these materials magnetic, they are subjected to a magnetic field by using an electric current. This process lines up the electrons (polarization) and they become magnetic.

But when entire life cycle emissions are considered (ground to steel), magnetite comes ahead of hematite, with a net savings of 108 kg CO2e per …

The prevailing process makes steel from iron ore — which is mostly iron oxide — by heating it with carbon; the process forms carbon dioxide as a byproduct. Production of a ton of steel generates almost two tons of CO2 emissions, according to steel industry figures, accounting for as much as 5 percent of the world's total greenhouse-gas ...

Iron & Steel Magnetic and strength properties make these materials essential for electrical products. The birth of the electrical industry began with the quest for pure iron. The movement of electrical technology has always depended on this workhorse of an element to make things happen. Iron is the core element used in many electrical things.

Some steels (steel is mostly made of iron) are more magnetic than others. Try comparing stainless steel with other kinds of steel you might find around the house. Two suggestions of things that can affect your experiments: 1) Rust and corrosion usually only occur in a very thin layer of the material near the surface.

Learn if steel is magnetic along with stainless steel and other metals. Why steel is a magnetic material has much to do with the elements that make up steel. Learn about the magnetic properties of galvanized, stainless, and mild steel and whether other metals …

The steel rod may be a knitting needle or a piece of clock spring. As a poor substitute, short pieces of thick piano wire can be used. Make sure the hard steel samples are not magnetized. If any are, de-magnetize them by passing them slowly through a coil carrying AC: for the 300-turn coil, use about 6 V AC: for the 2,400-turn coil, use about ...

The way I made it was…. Prepare an Fe+2 / Fe+3 (aq) solution in a 1 : 2 mole ratio. One may do this by dissolving some steel wool in Hydrochloride acid to make Iron (II) Chloride.

12L14 is commonly used because of the good machineability. It's magnetic properties are usually "good enough" but it all depends on how sensitive your application is to various properties. RE: Best steel for DC electromagnet. BobM3 (Mechanical) 21 …

Steel also displays ferromagnetic properties as it is derived from iron. Most steels will be attracted to a magnet. If needed, steel can also be used to make permanent magnets. Let's take the example of steel EN C15D. This grade of steel contains 98.81 to 99.26% iron. Thus, a very high percentage of this steel grade is iron.

"Help making non-magnetic stainless steel magnetic" 2004. Dear Gentlemen: I have found your site to be very interesting. I have a problem: my company has really cool bottle openers but they are made out of stainless steel and have no magnetic properties.

The magnetic properties of stainless steel are very dependent on the elements added into the alloy. A basic stainless steel has a 'ferritic' structure and is magnetic, formed from the addition of chromium – it can be hardened through the addition of carbon, making it 'martensitic'. However, the most common stainless steels are ...

The most common method of making magnets today involves placing metal in a magnetic field. The field exerts torque on the material, encouraging the domains to align. There's a slight delay, known as hysteresis, between the application of the field and the change in domains -- it takes a few moments for the domains to start to move.

Manganese Steel – 6 Things You Need to Know. 1. What is manganese steel? Manganese steel, also called Hadfield steel or mangalloy, is a steel alloy containing 12-14% manganese. Renowned for its high impact strength and resistance to abrasion in its hardened state, the steel is often described as the ultimate work hardening steel.

Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.

3 Methods of Magnetizing a Steel Bar | StudyElectrical.Com

Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite materials, such as magnetic polymers.

This invention is directed to a method of producing a non-oriented magnetic steel sheet involving a series of processes including performing hot rolling process on a steel slab containing no more than about 0.01 wt% C, no more than about 4.0 wt% Si, no more than about 1.5 wt% Mn, no more than about 1.5 wt% Al, no more than about 0.2 wt% P, and no more than about 0.01 wt% S, performing thereto ...

On the other hand, steel is said to shield, redirect or block magnetic fields. A magnet stuck to a steel washer won't stick nearly as well to a steel surface. The steel washer blocks the field from reaching it, and reduces the pull force. When we're asked about this kind of thing, our answer is often a frustratingly vague, "It depends.".
