摘要： A monolith holding material for a catalytic converter that is used in an exhaust emission control system of an internal combustion engine. The material comprises a compressed alumina fibrous mat uniformly containing therein organic binders that are thermally decomposed by high-temperature exhaust gas to exhibit thickness restoration properties, whereby surface pressures are caused to act on the outer circumferential surface of the monolith and the inner circumferential surface of a metallic casing to thereby hold the monolith therebetween. The monolith holding member has a superior durability and gas sealing property, whereby the catalytic converter survives a long-time service even after subjected to a strong vibration and impact.

摘要： An ultrahigh-strength and low-yield-ratio line-pipe steel being excellent in HAZ toughness and field weldability and having a tensile strength of at least 950 MPa (exceeding the API Specification 100). The steel comprises a low-C-high-Mn-Ni-Mo-Nb-trace Ti steel, further selectively contains if necessary B, Cu, Cr and V, and has as the microstructure a hard-soft two-phase mixed structure comprising martensite/bainite and 20-90 % of ferrite, the ferrite containing 50-100 % of worked ferrite and having a grain diameter of 5 mu m or less. It has thus become possible to produce an ultrahigh-strength and low-yield-ratio line-pipe steel (exceeding the API Specification 100) excellent in low-temperature toughness and field weldability. As a result, it has become possible to improve the pipeline safety remarkably and to improve the pipe-lining performance and conveying efficiency largely.
