Nichrome Alloy Cr30Ni70 Manufacturer in China | High-Quality Ni70Cr30 NiCr7030 Alloys

Cr30Ni70 alloy is a single-phase austenitic structure, with high nickel and chromium content and low iron content. It has good oxidation resistance, thermal strength and low positive temperature coefficient below 1050 ℃. It has high plasticity, cold stamping and welding performance at room temperature. The alloy is single-phase austenite after solution treatment, and the structure is stable during use. Cr30Ni70 has a wide range of applications. As a heating element, it is mainly used for periodic heat treatment furnaces with a temperature below 1050°C, such as carburizing furnaces, bell furnaces, etc., and can also be used as high-quality heat-resistant steel structural parts, such as furnaces. Used shafts, burning racks, etc. Products are mainly used in aerospace, petroleum and petrochemical, nuclear energy industry, chemical industry, marine industry, machinery manufacturing, communication electronics and other manufacturing fields, providing materials and component support for these fields in terms of high resistance, high temperature resistance, and corrosion resistance. Nickel-chromium alloys are usually smelted in a vacuum induction furnace to ensure the composition, control the gas and impurity content, and use the vacuum remelting precision casting method to make parts. In terms of heat treatment, solution treatment, intermediate treatment and aging treatment are required. Chemical composition%
