Chemical Make-up of Forged Alloy Steel By far the largest tonnage of alloy steels is of the types containing 0.20 to 0.55% carbon. ... Manganese, nickel, chromium, molybdenum, vanadium, aluminum and boron are commonly present in these steels to enhance the properties obtainable after quenching and tempering.
Alloy steel press forging

Long-term cooperation with petroleum, chemical, mining, and other enterprises. Supporting the production of sprocket, gear, gear ring, ring, cylinder, shaft, cylinder, block, module, support seat, flange and other forging products. If you need custom forgings, you are welcome to contact us in time.
The quality inspection of die forgings includes appearance quality inspection and internal quality inspection, including numerous inspection items respectively. The first is the chemical composition inspection, usually based on the smelting before the furnace sampling analysis as. Especially for important or suspect die forgings, some chips can be cut from the forgings and chemical composition can be tested by chemical analysis or spectral analysis. Secondly, the size and shape of die forgings are checked. Visual inspection is a more common method to observe the surface of forgings with the naked eye whether there are folding, cracks, bruises, scars, surface burns and other defects. And the surface of die forgings hidden deep defects, often after heat treatment and cleaning for observation. And its dimension measurement inspection includes length, width and height dimensions; Parallelism and perpendicularity of the plane; The curvature of the axis; Ellipticity of inner and outer circles; Radius of fillet; The concentricity; The included Angle and the misshift, etc. When the die forgings are required to carry out the precise size inspection, in addition to the marking inspection and the special sample can be used, the inspection instrument controlled and analyzed by the computer can be used, or the optical comparator, optical projector can be used for the relevant size inspection, to ensure the accuracy of the inspection results. Surface flaw detection is also a part of the quality inspection of die forgings. The surface quality of membrane acid and base is determined by magnetic particle test and fluorescence test. In addition, there are ultrasonic inspection, low tissue inspection, microscopic inspection, residual stress inspection and so on, each link can not be ignored.
Nickel-based shape memory alloy casting Category:Nickel alloy casting Nickel-based shape memory alloy casting is mainly used in aerospace and biomedical fields. Common grades are N06600 etc. Nickel-based shape memory alloy casting usually uses a vacuum induction furnace to smelt the master alloy to ensure the composition and control the gas and impurity content.Shape memory alloys are made of springs and other devices, and can also be used as fire prevention devices. It can also be used in various sensors. Nickel-based shape memory alloys usually refer to nickel-titanium alloys. By changing the proportion of titanium in the alloy, the recovery temperature of the alloy can be different. Because of the characteristics of shape memory alloys, it is widely used in the fields of aerospace and biomedicine. important role. Shape memory alloys have a shape memory effect, which can restore the shape before deformation at a specific temperature. At present, it plays an important role in the aerospace field and is used as an interface sealing function in pipeline transportation. In addition, it also plays a role in medicine, and can be used as artificial bones, spectacle frames and so on.
Nickel-based heat-resistant alloys Category:Nickel alloy casting Nickel-based heat-resistant alloys is a kind of nickel-based alloy, and the common grades are GH738, GH4738 etc. Product Description Nickel-based heat-resistant alloys is a nickel-based alloy. There are many different classifications of nickel-based alloy. Heat-resistant alloy is a material that can be used at high temperatures.For example, chemical and chemical equipment in the petrochemical field, atomic power generation in the energy field, comprehensive utilization of coal and other fields. The main elements of nickel-based heat-resistant alloys are nickel and chromium, and some other elements are also added to improve the solid solution strengthening of the alloy. They can still have high strength and oxidation resistance at high temperatures, and are often used in similar aircraft engines. and other high-temperature parts on the equipment. Nickel-based alloys can dissolve more elements in them, and can still maintain good organizational stability after dissolving the elements. The representative Incoloy alloy series is resistant to corrosion and creep resistance. It can also be used in Stress cracking is prevented to a certain extent.
