As supply chains shift and materials come from a wider range of sources, verifying the quality of incoming metals is more critical than ever. At King, we rely on Brinell hardness testing as a trusted, proven method for quickly assessing both material hardness and estimating tensile strength—giving you confidence before production begins.

Brinell testing for precise material verification

Brinell testing uses a hard steel or carbide ball pressed into the material surface under a controlled load, producing a large, easily measurable indentation. Unlike surface-only tests, Brinell provides a true representation of the metal’s bulk properties, making it ideal for heavy castings, forgings, and coarse-grained materials where surface inconsistencies can mask real performance.

Beyond hardness, Brinell results correlate strongly with ultimate tensile strength (UTS) in many steels and alloys. By applying standard conversion charts, Brinell hardness numbers (BHN) can offer a fast, reliable estimate of tensile strength—providing a practical alternative when destructive tensile tests aren’t feasible or economical.

In today’s environment, where documentation alone isn’t always enough, independent material verification is essential. Brinell testing offers a simple, robust, and highly effective tool to ensure your metals meet the demanding standards of high-heat, structural, and mission-critical applications.

At King, we combine deep expertise with state-of-the-art equipment to help you maintain quality, consistency, and peace of mind.
