Abstract BethStar 60 steel plate is a high-strength product with a 60,000 psi minimum yield strength. It contains low carbon and low sulfur and has outstanding toughness, weldability and formability. It provides the design engineer with a an economical high-strength low-alloy (HSLA) grade that can be fabricated readily. Applications include weight-sensitive components subject to high stress such as frames for large off-highway haulers. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, and joining. Filing Code: SA-421. Producer or source: Bethlehem Steel Corporation.

Abstract Böhler (or Boehler) S692 Microclean is a high sulfur, high carbon PM M4, with higher manganese and 0.22 sulfur for improved machining characteristics, and is available in rounds greater than or equal to 64.16 mm (2.562 in.) diameter. S693 Microclean is the low sulfur version of high carbon PM M4, available in flats and small diameter rounds. PM refers to powder metallurgy. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on surface qualities as well as heat treating and powder metal forms. Filing Code: TS-739. Producer or source: Böhler Edelstahl GmbH & Company KG.

Abstract An investigation was made of the effects exerted by benthic macroinvertebrate communities on copper speciation in sediments from a lake which is becoming acidified. In laboratory microcosms, benthic macroinvertebrate communities stimulated the flux of copper from sediment to water. The presence of the macro-benthos resulted in a redistribution of physico-chemical copper species within the sediment with a transfer from more strongly complexed forms (HC1 extractable) to adsorbed and cation exchangeable forms (MgCl2 extractable). The role of bio-turbation in copper transformations is discussed.
