What’s Chrome Steel?

Chrome steel is a type of steel mixed with chromium to prevent rusting. It is an alloy of six substances, with chromium being the most prevalent. It is magnetic and has high tensile and yield strength. It is forged in an electric arc furnace and undergoes heat treatment and acid wash. It is used in various products and tools, including kitchen utensils, drill bits, and architecture.

Chrome steel, also known as stainless steel, is steel that has been mixed with chromium. Chromium adds a special protection to steel which keeps it from rusting. Just like steel, chromium steel is an alloy or combination of two or more metals. Chrome steel is used for many applications, is easy to recycle and has a high scrap value.
A material, or chemical, analysis of chromium steel yields six substances: chromium, carbon, manganese, silicon, phosphorus, and sulfur. The amount of each substance used varies by metallurgist and creates a slightly different steel. Chromium is the most prevalent of the six and increases hardness, durability and hardness penetration.

Many metals are magnetic and stainless steel is no exception. One of the primary metals used in plain steel and chromium steel alloys is iron. Iron is completely magnetic. Stainless steel is commonly 96% iron, so this steel is also fully magnetic.

The tensile strength of stainless steel, or the strength of the metal under the greatest longitudinal stress, is 325,000 pounds per square inch (22,750 kilograms per square centimeter). This shows a high tensile strength. The yield strength, or when the metal deforms, is 295,000 PSI (20,650 kg/cm2. Both of these figures show that it is a strong and durable metal.

Chrome steel is forged in an electric arc furnace. The furnace includes carbon electrodes which blast a current through scrap steel placed in the furnace. Sometimes other elements are added, such as nickel and nitrogen. With true stainless steel, the chromium is added directly into the alloy. Imitation stainless steel uses a chrome plating, which has been shown to be less efficient than mixing chrome with steel.

After being counterfeited, there is still some processing to be done. It is annealed, or sent through a heat treatment, which softens the stainless steel so it is easier to melt and work with. It also goes through pickling, or an acid wash, which removes scale from the forging and annealing and also gives it a shiny surface.

Stainless steel is used in a wide variety of products and tools. In the home it is used for kitchen utensils and can also be found in drawer runners. For tools, it is used to make drill bits and wrenches. It is also used in architecture, both as an aesthetic and for its high resistance to corrosive substances such as salt and pollution.
