Hardness conversion table - Tensile strength, Vickers, Brinell och Rockwell (According to DIN 50150) The information below is for guidance only and should not be seen as fixed reference values. Some conditions, especially the incidence of cold work, can change the relationship between the tensile strength and hardness profoundly.
The S355 steel specifications are high yield non alloy steels. First specified in the European EN10025 standard and later published by the British Standards Institure (BSI) as BS EN 10025 S355, S355J2 and S355J2 N. These standards superceded the BS4360 grades. The average minimum yield for this material is 355 N/mm, hence the name S355.(plate) How to calculate flexural yield strength?

ASTM A370 provides the standard test methods and even a table which shows correlations between hardness in several different scales and the steel's tensile strength.
