Cr15Ni60 Resistance Strip – Reliable Nickel-Chromium Alloy for Industrial & Commercial Heating

Description

Cr15Ni60 resistance strip is a nickel-chromium alloy (60% nickel, 15% chromium) engineered for high-temperature applications requiring balanced oxidation resistance, mechanical strength, and cost efficiency. With a composition optimized for temperatures up to 1,150°C (2,102°F), this alloy forms a stable chromium oxide (Cr₂O₃) layer that resists scaling and degradation in oxidizing atmospheres. Its low iron content (≤1.0%) and controlled trace elements (e.g., manganese, silicon) ensure minimal embrittlement, making it ideal for cyclic heating environments such as industrial furnaces, electric heaters, and household appliances.

Certified to ASTM B344 and GB/T 1234 standards, Cr15Ni60 strip achieves a tensile strength of 600–750 MPa and elongation ≥25%, offering a cost-effective alternative to higher-nickel alloys like Cr20Ni80. With an electrical resistivity of 1.12 µΩ·m and a low temperature coefficient of resistance (TCR), it ensures stable energy output in air or inert gas environments, delivering consistent performance for applications ranging from thermal processing to consumer electronics.

Q&A

Q1: What is the maximum continuous operating temperature for Cr15Ni60 strip?
A: 1,100°C in oxidizing environments and 950°C in reducing or vacuum conditions.

Q2: How does Cr15Ni60 compare to Cr20Ni80 in terms of cost and performance?
A: Cr15Ni60 offers lower nickel content for cost savings while maintaining robust oxidation resistance, ideal for applications below 1,150°C.

Q3: Is pre-oxidation treatment necessary for optimal performance?
A: Optional. Heat-treating at 850–950°C for 1 hour enhances oxide layer adhesion, improving lifespan in cyclic operations.
