High-Temperature Resistant Alloy 602 CA Tubes for Heat Treatment Furnaces

Alloy 602 CA tube：

Alloy 602 CA is a high-performance nickel-based alloy known for its excellent high-temperature oxidation resistance and excellent structural stability, and is particularly suitable for long-term service in extremely high-temperature environments. The alloy is mainly composed of nickel, chromium, and iron, with a high proportion of chromium (about 25%) and a trace amount of yttrium (Y), which gives it surface stability and anti-stripping ability above 1100°C. In addition, yttrium can significantly improve the adhesion of the oxide layer, thereby enhancing the material's anti-stripping ability during thermal cycling. Alloy 602 CA has extremely high creep strength and can withstand long-term high stress loads. It also has good resistance to carburization and sulfur corrosion. It also performs well in weldability and formability, and is suitable for a variety of manufacturing processes.

Introduction to Quality Control Inspection Methods：

Quality Assurance for Raw Materials 

Our raw materials, sourced from esteemed steel mills such as Baosteel and Tsingshan, undergo stringent warranty and PMI checks to ensure top-notch quality. Stringent PMI checks and other inspections guarantee compliance with material specifications.

Supervised Production Process 

From cold rolling, cold drawing, annealing, to pickling and surface treatment, 321 stainless tube manufacturing process is meticulously overseen. Skilled engineers, equipped with advanced tools, supervise each phase and capture detailed records through photography. Process cards guarantee precision and traceability throughout production.

Quality Assurance Before Shipment

Our dedicated QC team conducts comprehensive inspections, encompassing appearance, PMI, size, quantity, and more. Mechanical, hardness, ultrasonic, eddy current, and hydraulic tests are carried out. We also welcome third-party evaluations (SGS, TUV, BV) and ensure secure packaging and container reinforcement to ensure product integrity during transportation.
