High Temperature Cr30Ni70 NiCr Alloy | Durable Industrial Electric Heating Material
At Beijing Shougang Jitai New Materials Co., Ltd., we specialize in the production of high-quality Cr30Ni70 nickel-chromium alloy, a premium material designed to meet the most demanding high-temperature applications. With decades of experience in the alloy industry, we are committed to providing our global customers with innovative, reliable, and cost-effective solutions.
Product Introduction
Designed to operate at continuous temperatures up to 1250°C, Cr30Ni70 excels where standard alloys fail. Its high chromium content provides an exceptional defense against high-temperature oxidation, while the high nickel matrix ensures superior resistance to carburization and nitrogen atmospheres.
As a flagship product of Beijing Shougang Gitane New Materials Co., Ltd., our Cr30Ni70 alloy is distinguished by its high resistivity (1.18 Ω·mm²/m), morphological stability, and excellent weldability. Unlike ferritic alloys, it maintains outstanding malleability even after prolonged use, allowing for easier maintenance of complex heating elements. Whether for aerospace turbines, heavy-duty industrial kilns, or precision laboratory equipment, Cr30Ni70 provides the durable, high-emissivity (0.88) solution required for efficient energy transfer and long-term structural integrity.
