Abstract UNS No. T30407 is a high-carbon chromium cold-work tool steel containing vanadium (4.0%) and molybdenum (1.0%). Its carbon and vanadium form a vanadium carbide that provides war resistance many times greater than that of UNS No. T30403 (AISI Type D3). UNS No. T30407 was developed for applications where extreme abrasive wear is needed. Its many applications include briquetting dies and punches, brick mold liners, pottery, tools, broaches, meat-chopper plates and cold-extrusion dies. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-439. Producer or source: Tool steel mills.

The formation of Oxygen paramagnetic adducts of Co(II) containing ion-exchange resins in the presence of adsorbed ethylenediamine has been found. The EPR parameters of a complex of the type Co(III) (en)2O-2 and of O-2 species formed in the presence of Co(en)2+3 have been described. The catalytic properties of Co-ethylenediamine surface complexes with respect to the hydrogen peroxide decomposition reaction have been investigated and a probable mechanism has been suggested.
