BS1501-430A - Macsteel

Impact resistanceNote:1. The specification has no impact test requirements for steel type 161.Elevated temperature yield strength or proof stressIn appendix D (for steel types 151 and 161) and appendix F (for steel type 224). Thespecification shows the yield strength or proof stress valuesof the respective grades at elevated temperature.These values may be used for design purposes, but if a user requires verification of thestrength at any particular temperature, a tensile testat this temperature must be stipulated on the order. The high temperature yield strengthvalues for these steels are summarized in thetable below.Table 3.
