1. Excellent Corrosion Resistance
AL-6XN is a super austenitic stainless steel with high chromium, high molybdenum, and high nitrogen content, with a PREN > 45, enabling it to maintain a longer service life in chemical processing and marine environments.
2. High Strength and Excellent Toughness
Our AL-6XN tubing utilizes precise heat treatment and solution annealing control to ensure consistent mechanical properties. It offers superior toughness and mechanical properties compared to traditional alloys.
3. Excellent Weldability and Machinability
Our AL-6XN tubing undergoes chemical composition testing to ensure compliance with ASTM A249 standards. It can be welded using standard austenitic stainless steel welding techniques, and the tubing supports cold bending, flaring, and expansion.
4. Quality Control
Our tubing undergoes rigorous 100% quality testing, including dimensional inspection, mechanical property testing, hydrostatic testing, and ultrasonic flaw detection, to ensure long-term durability.
5. After-Sales Service
TORICH provides professional after-sales service. If any non-conformity is confirmed, we will promptly take repair, replacement, or compensation measures in accordance with the contract terms to minimize downtime and project impact.
