The phrase "an approximate strength of" is correct and usable in written English.
It can be used when discussing a measurement or estimation of strength in various contexts, such as engineering, materials science, or physical fitness.
Example: "The engineer reported an approximate strength of 300 megapascals for the concrete mix used in the construction."
Alternatives: "an estimated strength of" or "a rough strength of".
