Yuhong Group Co., Ltd. is pleased to announce the successful shipment of ASTM B622 Hastelloy C276 (UNS N10276) seamless tubes, securely packed in export-standard plywood cases and dispatched to our international client for critical chemical processing applications.

The shipment was carefully prepared with professional export packaging — each tube individually protected and secured within reinforced wooden crates — ensuring product integrity throughout ocean freight and land transportation.

ASTM B622 specifies seamless nickel-chromium-molybdenum alloy pipe and tube. Hastelloy C276 (UNS N10276) is one of the most versatile corrosion-resistant alloys available, offering exceptional resistance to a wide range of aggressive chemical environments including strong oxidizers, reducing acids, and chloride-bearing media.

Hastelloy C276 is widely recognized for its outstanding performance in the most demanding industrial environments:

• Superior Pitting & Crevice Corrosion Resistance — High molybdenum content (15–17%) provides excellent resistance to localized corrosion in chloride-containing environments, outperforming standard austenitic stainless steels.
• Resistance to Oxidizing & Reducing Media — The balanced chromium-molybdenum-tungsten composition delivers resistance to both oxidizing acids (nitric, chromic) and reducing acids (hydrochloric, sulfuric).
• Excellent Stress Corrosion Cracking (SCC) Resistance — Unlike 300-series stainless steels, C276 resists chloride-induced SCC, making it ideal for heat exchanger tubing in aggressive chemical services.
• Good Weldability — C276 can be welded without post-weld heat treatment while retaining corrosion resistance in as-welded condition.

Every shipment of ASTM B622 C276 seamless tube from Yuhong Group is delivered with complete documentation:

• Mill Test Certificate (MTC) to EN 10204 Type 3.1, with full chemical composition and mechanical property data
• Hydrostatic Test Report confirming each tube meets pressure integrity requirements
• Non-Destructive Testing Reports including Eddy Current Testing (ECT) and Ultrasonic Testing (UT)
• Dimensional Inspection Report with OD, wall thickness, and length measurements

At Yuhong Group, we maintain extensive inventory of nickel alloy seamless tubes and pipes, including Hastelloy C276, C22, Inconel 600/625, Incoloy 800/825, Monel 400, and other specialty grades. Our products serve projects across more than 85 countries with full international certification compliance.
