| 420094000 | Over 10 percent nickel containing | 7 |
| 20090148336 | CAST-IN CEMENTED CARBIDE COMPONENTS - The present invention relates to a compound body comprising cemented carbide and steel with a carbon content corresponding to a carbon equivalent Ceq=wt-% C+0.3(wt-% Si+wt-% P) of from about 0.1 to about 0.85 wt-%. The body is particularly useful for earth moving tools e.g. dredge cutter heads. | 06-11-2009 |
| 20140212324 | FINE CRYSTALLITE HIGH-FUNCTION METAL ALLOY MEMBER AND METHOD FOR MANUFACTURING SAME - Provided by the present invention are a fine crystallite high-function metal alloy member, a method for manufacturing the same, and a business development method thereof, in which a crystallite of a metal alloy including a high-purity metal alloy whose crystal lattice is a face-centered cubic lattice, a body-centered cubic lattice, or a close-packed hexagonal lattice is made fine with the size in the level of nanometers (10 | 07-31-2014 |
| 420095000 | Cobalt containing | 3 |
| 20100086433 | Iron-nickle alloy with a high level of ductility and a low expansion coefficient - The invention relates to a solid-solution strengthened iron-nickel alloy with a high level of ductility and an expansion coefficient <5×10 | 04-08-2010 |
| 20100316523 | Iron-Based Alloy Powder - A powder for a sintered valve sheet made of an iron-based alloy is provided, which has excellent compactibility and abrasion resistance and from which a carbide that may abrade a counterpart is not precipitated. A powder is provided, wherein a molten steel, in which carbon is controlled to be less than 0.1% by mass to avoid precipitation of a carbide, 0.5 to 8.5% by mass of Si, 10 to 25% by mass of Ni, 5 to 20% by mass of Mo, and 5 to 20% by mass of Co are contained, and a remainder includes Fe and incidental impurities, is rapidly cooled by a conventional technique such as a gas atomization method, a water atomization method, or a centrifugal force atomization method, so that a supersaturated solid solution of the alloy elements consisting mainly of austenite, which is effective in softening the powder, is formed. Since the powder has low hardness, the compactibility is excellent at the time of compression molding. On the other hand, since the powder is hardened after sintering, a valve sheet as a final product has excellent abrasion resistance. In addition, since no carbide is precipitated, the counterpart may not be abraded. | 12-16-2010 |
| 20160376686 | Lower-Cost, Ultra-High-Strength, High-Toughness Steel - A non-stainless steel alloy includes, in combination by weight, about 0.20% to about 0.33% carbon, about 4.0% to about 8.0% cobalt, about 7.0 to about 11.0% nickel, about 0.8% to about 3.0% chromium, about 0.5% to about 2.5% molybdenum, about 0.5% to about 5.9% tungsten, about 0.05% to about 0.20% vanadium, and up to about 0.02% titanium, the balance essentially iron and incidental elements and impurities. | 12-29-2016 |
| 420096000 | Molybdenum containing | 2 |
| 20090142220 | SINTER-HARDENING POWDER AND THEIR SINTERED COMPACTS - A sinter-hardening raw powder can yield a press-and-sinter compact with high hardness. The raw powder for sintering includes Fe as its primary component and also includes 0.3-0.8 wt % C, 5.0-12.0 wt % Ni, 1.0-5.0 wt % Cr, and 0.1-2.0 wt % Mo, wherein the mean particle size of the raw powder for sintering is between 50 and 100 μm. The sintered and tempered compact, without any quenching treatment, has high hardness. | 06-04-2009 |
| 20100143181 | High strength austenitic trip steel - An austenitic TRIP steel consisting essentially of, in weight %, 0.14 to 0.18% Al, 2.8 to 3.2% Ti, 23.5 to 23.8% Ni, 3.8 to 4.2% Cr, 1.1 to 1.3% Mo, 0.29 to 0.31% V, 0.01 to 0.015% B, 0.01 to 0.02% C, and balance Fe and incidental impurities exhibits combined high yield strength and high strain hardening leading to improved stretch ductility under both tension and shear dynamic loading conditions. | 06-10-2010 |
