Highly Corrosion-Resistant 400 Nickel—Commonly found in the oil and gas industries, these washers have similar strength to 316 stainless steel, but are more corrosion resistant to stand up to salt water and harsh acids. They're often used as a high-strength alternative to titanium. Also known as Monel.
Material Certificate—Washers include a report with a traceable lot number.
