High Carbon Steel Flat Washer Frequently Asked Questions

Below are answers to some of the most common questions about high carbon steel flat washers.

What are high carbon steel flat washers?
High carbon steel flat washers are manufactured from high carbon steel (typically 1050 through 1095 grade), which has significantly higher hardness and tensile strength than low carbon steel. High carbon steel washers are used in applications requiring maximum hardness, wear resistance, or spring-like resilience, such as under high-tension fasteners, in locking mechanisms, and as hardened bearing surfaces.

When should I use high carbon steel washers instead of low carbon steel?
High carbon steel washers are specified when the application requires a hardened bearing surface under a high-strength fastener, when the washer must resist deformation under high clamp loads, or when wear resistance is a priority. Low carbon steel washers are used for general-purpose load distribution where hardness is not critical.

Do high carbon steel washers require a finish or coating?
High carbon steel is susceptible to corrosion and typically requires a protective finish for most applications. Common finishes include zinc plating, phosphate, black oxide, and oil. For corrosive environments, stainless steel is generally a better choice than coated high carbon steel. Contact us to specify a finish if required.

Can you make custom high carbon steel flat washers?
Yes. Superior Washer manufactures custom high carbon steel washers to your OD, ID, and thickness specifications. Contact us via the Quick Quote form or by phone.

Are your high carbon steel flat washers made in the USA?
Yes. All high carbon steel flat washers are manufactured in the United States under our ISO 9001:2015 certified Quality Management System. Material certifications are available upon request.
