Material Overview

Hastelloy® C276 (UNS N10276, W.Nr. 2.4819) is a premium nickel-molybdenum-chromium-tungsten alloy renowned for its exceptional corrosion resistance across a wide range of aggressive chemical environments—both oxidizing and reducing. Our Hastelloy C276 round bars are precision-manufactured to meet international standards and can be custom-cut to your exact length requirements, ensuring seamless integration into your industrial applications.

Ideal for use in chemical processing, oil & gas, pollution control, and marine engineering, C276 round bars offer unmatched durability in the presence of chlorides, acids, and high-temperature corrosive media.

Chemical Composition

Element	Content (%)
Nickel (Ni)	52.0 - 60.0
Molybdenum (Mo)	15.0 - 17.0
Chromium (Cr)	14.5 - 16.5
Iron (Fe)	≤ 5.0
Tungsten (W)	3.0 - 4.5
Carbon (C)	≤ 0.01
Manganese (Mn)	≤ 1.00
Silicon (Si)	≤ 0.08
Phosphorus (P)	≤ 0.040
Sulfur (S)	≤ 0.030
Cobalt (Co)	≤ 2.5

Note: C + S ≤ 0.05% as per ASTM B574. This balanced composition provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking—even in wet chlorine, hypochlorite, and chloride-rich environments.

Mechanical Properties

Property	Value
Tensile Strength (Rm)	≥ 690 MPa (100 ksi)
Yield Strength (Rp0.2)	≥ 283 MPa (41 ksi)
Elongation (A5)	≥ 40%
Hardness (HB)	≤ 241
Density	8.9 g/cm³
Melting Range	1325-1370°C (2417-2498°F)

These properties ensure excellent formability, weldability, and structural reliability under demanding service conditions.

Standards & Certifications
