Bolts Equivalences

(OP)
Dear Colleagues:

I'm a Mech Eng. who has 10 years experience in pressure vessels design,using ASME , ADmerk , CODAP Code but my strong labour was in ASME. Now, when I design using ADM Code, I get some troubles with Bolt K values using to determine allowable stress.

In this case, I've a ASTM A-193 Gr B7 and I try to use it ina ADM Design , What kind of values shall be used? K20 and K(D. Temp.)?, I guess these values are really higher, because we are talking about 105 Ksi (724.2 MPa).
Could anyone help me?. There is not a direct equivalence between this bolt and german material bolt.

Thanks in advanced

Calidad (José Luis Gómez R.)
