Hastelloy C-276 en Mecanizado CNC
Hastelloy C-276 is a nickel-molybdenum-chromium superalloy known for its exceptional corrosion resistance, especially in harsh chemical environments.
It is widely used in CNC machining due to its durability, oxidation resistance, and ability to withstand extreme conditions, including strong oxidizing and reducing agents. At DEK, we leverage advanced CNC 5-axis machines and wire EDM to shape C-276 with precision up to ±0.005 mm, meeting the needs of complex designs.
C-276 maintains high mechanical strength while offering outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. It is commonly used in chemical processing, marine, aerospace, and power plants. However, due to its toughness, machining Hastelloy C-276 requires specialized tools and cutting strategies to reduce work hardening and tool wear.

Conocimientos básicos of Hastelloy C-276
What is Hastelloy C-276?
Hastelloy C-276 is a corrosion-resistant nickel alloy primarily composed of nickel (57%), molybdenum (16%), chromium (15%), and iron (5%) with small amounts of cobalt and tungsten. It is one of the most versatile corrosion-resistant alloys available, ideal for environments involving strong oxidizers, reducing agents, and extreme heat.
This alloy is commonly used in applications where other materials fail due to corrosion or high temperatures. Hastelloy C-276 is also preferred due to its ability to resist localized attacks like pitting and crevice corrosion. It is a reliable choice for aggressive industrial environments.
