Rhodochrosite is mainly used as an ore of manganese, which is a key component of low-cost stainless steel formulations, many tool steels, and certain aluminium alloys. [9] Quality banded specimens are often used for decorative stones and jewellery.
The average carbon footprint of stainless steel (all grades, all countries) is estimated to be 2.90 kg of CO 2 per kg of stainless steel produced, [88] of which 1.92 kg are emissions from raw materials (Cr, Ni, Mo); 0.54 kg from electricity and steam, and 0.44 kg are direct emissions (i.e., by the stainless steel plant). Note that stainless ...

In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...
Stainless steel nipple jewelry 316L stainless steel, unpolished straight from the foundry. Surgical stainless steel is a grade of stainless steel that is used in biomedical applications. The most common "surgical steels" are austenitic 316 stainless and martensitic 440 and 420 stainless steels.
Ferritic stainless steel alloys are designated as part of the 400-series of stainless steels in the SAE steel grades numbering system. By comparison with austenitic stainless steels, these are less hardenable by cold working and less weldable, but more cost-effective due to the lower nickel content.
Art jewelry is one of the names given to jewelry created by studio craftspeople in recent decades. As the name suggests, art jewelry emphasizes creative expression and design, and is characterized by the use of a variety of materials, often commonplace or of low economic value. In this sense, it forms a counterbalance to the use of "precious ...
