Each Hastelloy washer is precision-engineered to ensure exceptional sealing, load distribution, and resistance to corrosion. We provide a variety of washer types, including flat, spring, and lock washers, made from Hastelloy grades like C-276, C-22, and B-2. These washers are essential in critical applications across various industries such as chemical processing, marine, aerospace, and power generation, meeting international standards for durability in harsh chemical and high-temperature conditions.
Hastelloy Washers are crafted from corrosion-resistant alloys like Hastelloy C-276, C-22, and B-2. These alloys typically contain 57–60% Nickel, 15–22% Molybdenum, 14–16% Chromium, along with trace amounts of iron, cobalt, and tungsten. They are known for their outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. In terms of mechanical properties, they boast tensile strength ranging from 690–850 MPa, yield strength between 300–450 MPa, and elongation up to 45%. Their robust structural integrity under high pressure, chemical exposure, and elevated temperatures makes them perfect for critical sealing and fastening tasks.

Hastelloy Washers find their place in environments where standard materials would typically corrode or fail. They are commonly used in chemical reactors, valve assemblies, heat exchangers, offshore platforms, and marine equipment, particularly in situations involving strong acids like sulfuric, hydrochloric, or nitric acid. Additionally, these washers are utilized in pharmaceutical equipment, pulp and paper mills, and pollution control systems. Their remarkable chemical resistance guarantees secure sealing in flanged connections, bolted joints, and mechanical assemblies, even when under significant stress.
