(OP)
Is there any body to know the mechanical and chemical composition of material ASTM A212-Gr.B that has been replaced with A515? And which garde of A515 is equal to A212-Gr.B?

RE: ASTM A-212 Gr.B PROPERTIES
SA212-B properties from the 1962 edition of ASME VIII (trick question: the '62 ed. of Div 1 or Div 2?):
Nominal composition: C-Si
P number 1
Min Tensile 70,000 psi
Allow stress -20 to 650°F: 17,500 psi
Allow stress at 1000°F (max listed temp): 2,500 psi
(several intermediate temperature / stress values also listed)
SA515-70 has the same nominal composition, min tensile, and allowable stress at 1000°F. I'd tend to use SA516-70 (C-Mn-Si) though, instead of SA515. I'm just more familiar with it.
