Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

The Manganese Mining Process. More than 25 million tons of manganese are mined every year. Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it's transferred to a processing …

If the Manganese has work-hardened in service (such as may likely be encountered in repair jobs), cut away the hardened surface. Then apply a "butter-coat" of 307 stainless. The hardened surface, if not removed, will contribute to embrittlement and eventual fracture at the welded area. Peen the welds while hot.

Manganese has similar effects like carbon, and steel producers use both of these elements to achieve a material with preferred properties. Manganese is required for the hot rolling process of steel by combining it with sulfur and oxygen. Steels often include 0.30% manganese, but certain carbon steels can include up to 1.5% of manganese.
