Description du produit

L'Hastelloy C-276 (UNS N10276) est un alliage nickel-chrome-molybdène contenant du tungstène largement considéré comme l'un des matériaux résistants à la corrosion les plus polyvalents disponibles. Le tuyau Hastelloy C-276 est fabriqué à partir de cet alliage et est spécialement conçu pour être utilisé dans les environnements corrosifs les plus exigeants des industries de traitement chimique, du pétrole et du gaz, de la marine, de l'ingénierie environnementale et de la production d'électricité.

Avec plus de 50 ans de performances éprouvées sur le terrain, le C-276 est devenu le matériau de prédilection lorsque les aciers inoxydables standards et les alliages de nickel de qualité inférieure ne sont pas à la hauteur.

Hastelloy C-276 Pipe — Product Introduction

What Is Hastelloy C-276 Pipe?

Hastelloy C-276 (UNS N10276) is a tungsten-containing nickel-chromium-molybdenum alloy widely regarded as one of the most versatile corrosion-resistant materials available. Hastelloy C-276 pipe is manufactured from this alloy and is specifically designed for use in the most demanding corrosive environments across chemical processing, oil & gas, marine, environmental engineering, and power generation industries.

With over 50 years of proven field performance, C-276 has become the go-to material when standard stainless steels and lower-grade nickel alloys fall short.

Key Features

Outstanding Corrosion Resistance — Performs exceptionally well in both oxidizing and reducing media, including sulfuric acid, hydrochloric acid, phosphoric acid, wet chlorine gas, hypochlorite, and chloride-containing solutions.
Superior Pitting & Crevice Corrosion Resistance — With a PREN (Pitting Resistance Equivalent Number) typically above 65, C-276 far exceeds conventional duplex stainless steels and austenitic alloys like 316L.
Stress Corrosion Cracking (SCC) Immunity — Highly resistant to chloride-induced SCC, a common failure mode for austenitic stainless steels.
Excellent Weldability — Ultra-low carbon (≤0.01%) and silicon (≤0.08%) content minimizes carbide precipitation in the heat-affected zone. Welds can be used directly without post-weld heat treatment.
Good Formability — Ductile and easy to form, with elongation ≥40%, allowing fabrication into complex piping configurations.
High-Temperature Strength — Maintains yield strength above 300 MPa even at elevated temperatures (400–700°C).
