Cr20Ni40 NiCr Alloy | High Temperature Electric Heating Element Material – SPARK
GITANE specialize in the production of high-quality Cr20Ni40 nickel-chromium alloy, a premium material designed to meet the most demanding corrosion and 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
As a flagship product of GITANE (Beijing Shougang Gitane New Materials Co., Ltd.), our Cr20Ni40 is distinguished by its exceptional morphological stability and weldability. While traditional alloys may struggle in fluctuating thermal cycles, Cr20Ni40 maintains its strength and structural integrity up to 1100°C. Its standout feature is its superior resistance to stress corrosion cracking and chemical attack, making it the preferred choice for chemical processing reactors, marine engines, and specialized heating systems. Whether you are operating in saltwater environments or handling acidic industrial media, the Cr20Ni40 alloy provides a durable, non-magnetic, and cost-effective thermal solution with a high emissivity of 0.88.
