Thanks for your response. Yes I agree, it is difficult to count on these numbers. According to chinese standards. The Chemical Composition of these materials should be as follows. C-0.2,Si-0.55,Mn-1.00-1.6,P<0.045,S<0.035,V-0.02-0.2,NB-0.015-0.060,Ti-0.02-0.20,AL>0.015,CR<0.030,NI<0.7. The...

I have a steel material that has a yield strength of 515 mpa and a tensile strength of 615 mpa at zero degrees. What i need to know is will the tensile strength and yield strength be higher than 293 mpa at 80 degrees. The steel is ahigh tensile grade steel from china (Q390C).
