How strong are the superior-strength ABS steels?
The ABS 32 grades, including AH32, DH32, and EH32, have a yield strength of 45,500 psi (315 MPa) and the 36 grades, including AH36, DH36, and EH36, have a yield strength of 51,000 psi (355 Mpa). The ultimate tensile strength of the 32 grades is 64,000 – 85,000 psi (440 – 590 MPa) and for the 36 grades it is 71,000 – 90,000 psi (490 – 620 MPa).
In comparison, ABS A & B are defined as ordinary strength and have specified yield points of 34,000 psi (235 MPa) and ultimate tensile strengths of 36,000 – 71,000 psi (400 – 490 MPa).
However, there are exceptions for greater thicknesses and certain sections.
