Cross-reference A570 to A1011
Cross-reference A570 to A1011
(OP)
I have a material reference to ASTM A570, Grade C. Since this is a withdrawn standard, replaced with A1011, my vendors will not or can not certify to A570. I read copies of the 1998 and 1984a version of A570, but can't find a refernce to a Grade C.
Matweb has one

but that doesn't really help me determine the material callout in reference to A1011.
Can someone point me to a cross reference from A570, Grade C to its equivalent A1011 grade, type, and class?
Thanks

I *think* these are the correspondences, but some confirmation would be good:
letter number
A 36 Type 2
B 36 Type 1
C 33
D 30
A 1011 has the same grade numbers as A 570, so A 570 Grade C is probably A 1011 Grade 33.

I also wrote to ASTM so with your info at least I can look for a specific revision year to find the change rather than each revision backwards from now until 1970.

Comparing the 72 with 79 & 84a and 98 editions of A570:
72 --> 79 & 84a --> 98
A --> No direct comparison --> NDC
B --> 30 --> 30
C --> 33 --> 33
--> 36 --> 36 Type 1
--> 36 Type 2
D --> 40 --> 40
E --> No direct comparison --> NDC
--> 45 --> 45
--> 50 --> 50
--> 55
