Houston, USA-based Brian Fasteners is a top-tier producer and supplier of Hastelloy Washers for industrial use where excellent corrosion resistance and mechanical performance are demanded. Our washers are high-precision machined from premium-grade Hastelloy alloys like C276 and C22, renowned for their strength in harsh chemical environments. With load distribution abilities and stress resistance, these washers provide leak-free joints to high-pressure systems. At Brian Fasteners, we operate high standards of quality control and industry compliance to supply dependable fastening components for applications in chemical processing, marine, pharmaceuticals, and power generation.
Hastelloy Washers are largely produced with nickel-molybdenum-chromium alloys like Hastelloy C276 (57% Ni, 16% Mo, 15.5% Cr, 5.5% Fe). These alloys exhibit superior resistance to severe oxidizers, chlorides, and reducing agents. Mechanical properties are tensile strength 100–115 ksi, yield strength of approximately 45 ksi, and Rockwell hardness B90–C30. Washers have mechanical stability over a broad range of temperature and resist pitting, stress corrosion cracking, and crevice corrosion. Their endurance provides long service life in aggressive media where other alloys deteriorate.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Hastelloy Washers are perfect for chemical processing systems that are exposed to vigorous acids like sulfuric, hydrochloric, and nitric acids. They are widely applied in heat exchangers, valves, pumps, and flanged connections of pharmaceutical, marine, and wastewater treatment plants. In power plants, they maintain high-stress joints of boilers and turbines, withstanding both thermal expansion and corrosion. Their performance in biotech and food industries stands out for hygiene-critical and corrosive installations. These washers offer sealing integrity and mechanical strength in conditions where typical stainless steel would corrode extensively.
We at Brian Fasteners make sure that our Hastelloy washers are packed with great care and precaution. The washers are packed in groups of one each in individual protective covers to avoid scratching, rusting or getting contaminated in the process. Some of our packaging products include; cartons that are highly durable and packaging solutions that are made to order. They help in easy identification and packing to enhance our reputation of delivering quality products in good condition.
