The high-strength low-alloy steels represent a relatively recent development in steelmaking. The higher strength (42 to 65 ksi) is achieved by adding small amounts of additional chemical elements. Two of the most common HSLA steels are ASTM grade A572 and A588. The high-strength quenched and tempered (Q&T) alloy steels used for structural ...

The dashed line estimates the increase in mill capacity in going from a high-volatile B bituminous coal with a 55 HGI, 12% moisture and a desired mill output of 70% through a 200 mesh screen to a highvolatile B bituminous coal with an HGI value of 60, a moisture content of 14% and the same fineness.

Applications for Chrome White Iron. Pumps, impellers and suction or bearing liners are some of the most common uses for chrome white iron. Chute liners, apron-feed liners, and gyratory crusher liners are very common uses in the mining industry. Recycling-plant parts like blow bars, anvils and throw shoes are best made in high chrome white iron.
