Hello Delaforce,
thanks for answered at my question.
In my version of CII 5.10.03(Build 090206) allowable of 1.0345S-16 from -40°C to 170,5°C is costant =120MPa, at 200°C allowable is 113,3MPa. In your example at 150°C, Rp0,2% is 198MPa thus f = min(360/2,4; 198/1,5) = 132 MPa, ok I agree, in CII material database at 150°C i found allowable 120MPa because in EN13480-3 chapter 12.1.3.2 fc=min(Rm/3;froom) & fh=min(fc;ft;fcr) thus 360/3=120 < 132, it matches with CII material database.

At 200°C Rp0,2% is 182MPa and ft= 182/1,5 = 121,3MPa thus fmin=120MPa, why in CII is 113,3MPa? Creep start at 380°C thus fcr is not considered in equation, is it right?.

At 400°C (creep range) value of Creep Rupture strenght is 191MPa for 10000h, 132MPa for 100000h and 115MPa for 200000h. fcr = SRTt/SFcr=132/1,5= 88MPa or 115/1,25= 92MPa [SFcr by table 5.3.2-1 EN13480-3]. In CII value of allowable is 74,67MPa, i don't understand how is calculated, please can you explain me how are obtained?.

Thanks
Best Regards
