Ultra-Durable and Chip-Resistant: High-manganese titanium alloy chain with a hardness of HRC 60+, 3 times more durable than ordinary chains! Easily cuts through knotty hardwoods and old tree roots without chipping, eliminating the hassle of frequent chain replacement. Low-Temperature Annealing Process: -196℃ deep cryogenic treatment technology eliminates internal metal stress, preventing overheating and breakage during high-speed cutting. The chain remains undeformed even after 2 hours of continuous operation, ensuring safer and longer-lasting performance. Silent and Vibration-Dampening Design: Low-noise guide tooth structure + vibration-damping connecting plates, resulting in working noise ≤85dB. Trim trees in the early morning without disturbing neighbors; perfect for use in residential areas and gardens. Safe Anti-Kickback: Buffered limit tooth design automatically slows down upon accidental contact with hard objects, reducing the risk of kickback, ensuring peace of mind for home users. Precision-stamped oiling holes increase lubrication coverage by 40%, reducing chain friction, saving 15% on oil consumption while also reducing sawdust splatter for easier cleanup. for Husqvarna 440 435 445 450 545, 345, 350, 51, Poulan 4620, ECHO CS-400-591094872, 20lpx072g, Oregon H72 M72 and More CHAINS SPECIFICATIONS：5 packs 18 Inch, .325" LP Pitch, .050" Gauge, 72 Drive Links(Please check the length, pitch, chain thickness, and number of drive chain links to ensure this chain is suitable for your machine）
