![]() Unlike silver jewelry or alloy jewelry (copper alloy, pewter alloy, zinc alloy, etc.), it will rust, corrode and blacken the surface if worn for a long time. High hardness and strong corrosion resistance. Both 316 and 316L (L is low-carbon) are molybdenum-containing stainless steel, and the highest grade of stainless steel jewelry currently is 316L, which can reach medical grade without causing any adverse side effects to the human body, so it is very safe.ġ. ![]() The standard composition of 304 is more than 18% chromium and more than 8% nickel the standard composition of 316 is more than 16% chromium and more than 10% nickel and contains some molybdenum elements. The most commonly used stainless steel jewelry is the 300 series of 304 and 316 specifications. The larger the quantity, the higher the quality and the higher the cost. Priest Prayer Cross Stainless Steel Gold RingĪccording to its chemical composition, stainless steel can be divided into 200 series, 300 series, 400 series, 500 series, and 600 series. This is because when the chromium content of steel reaches about 12%, under chemical action, an oxide film will form on the surface of the steel to prevent it from further corrosion. The higher the chromium content, the higher the corrosion resistance. Chromium is the basic element for corrosion resistance. The degree of corrosion resistance of the two depends on their chemical composition of two. Generally, stainless steel is resistant to weak corrosive media such as steam and water, and air, while acid-resistant steel is resistant to chemical corrosive media such as alkali, salt, and acid. Stainless steel refers to steel with a chromium content of not less than 10.5% and a carbon content of not more than 1.2%, rust-free and corrosion-resistant. Stainless steel jewelry or gold and silver jewelry?.There are many kinds of stainless steel jewelry, how do match them?.Five common processes of stainless steel jewelry.
