A335-P92 Material Properties

Question

Hello! 
 We can use A335-P92 material in AutoPIPE, but I don't know where the material properties come from. 
 I can find only thermal expansion coefficient and allowable stress from ASME B31.1 and ASME Sec II, Part D respectively. But they are a little bit different from the values in AutoPIPE. 
 Even, I can't find elastic modulus of A335-P92 in code. 
 What is the basis of A335-P92 material properties in AutoPIPE?

Hello Hyukchan Kwon, 
 See WIKI here , example #3, for details on how to find out this information from AutoPIPE help. It is a very simple process. To answer your question directly for material library = B311-14: 
 From the Code Dependent Pipe Materials , find the following: 
 
 Use UC1, and open the same code year Standard Pipe Material library to find the following: 
 
 Answer: 
 Yield Stress values were taken from ASME B31.1 - 2014 Ultimate Stress values were taken from ASME B31.1 - 2014 Allowable Stress value were taken from ASME B31.1 - 2014 Thermal Expan. Coef. values were taken from T92/P92 Book, Vallourec & Mannesmann Tubes (2000) Young's Modulus values were taken from T92/P92 Book, Vallourec & Mannesmann Tubes (2000)
