Validated correlations for yield strength, tensile strength and total elongation from above table which result in optimum value of error and correlation coefficient(r) are respectively as follows- =0.17× 0.1 , ℎ 02 +172.35 (28) =0.088× ℎ 02 + 32.81 (29) = 9.98 × (30)

6. Conclusion The Small punch test can be used to evaluate tensile properties of metallic materials using minimal amount of material. SPT was used to derive tensile properties of low alloy steel in different material condition. Empirical
