Productomschrijving

Alloy C-22 (HASTELLOY C-22) Seamless Pipe

Size: 15 (O.D. 21.3mm) × 2.1mm thickness × 2,000mm length

Product Overview

Hastelloy C22 Seamless Nickel Alloy Tube ASTM B622 Seamless Round Tube

Alloy C-22 is an enhanced nickel-chromium-molybdenum-tungsten alloy designed for superior performance in aggressive industrial environments. This alloy demonstrates exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making it ideal for demanding applications.

Key Advantages

Superior overall corrosion resistance compared to Alloy C-276
Outstanding resistance to chloride pitting, crevice corrosion, and stress corrosion cracking
Excellent performance in oxidizing aqueous environments including wet chlorine and nitric acid/chloride mixtures

Fabrication Guidelines

While ductile enough for cold working, intermediate annealing may be required due to work hardening. Forging should occur between 1750-2050°F followed by rapid cooling. Annealing is recommended at 2020-2150°F with rapid quenching to prevent formation of detrimental phases between 1400-1800°F. Welding can be performed using gas tungsten-arc, gas metal-arc, and shielded metal-arc processes.
