ABS AH36, ABS DH36, and ABS EH36 are all grades of steel plates that are certified by the American Bureau of Shipping (ABS). These grades are commonly used in the construction of ships and marine structures due to their high strength and excellent corrosion resistance.

1. ABS AH36: Has a minimum yield strength of 51,000 psi (355 MPa) and a minimum tensile strength of 71,000 – 90,000 psi (490-620 MPa).
   
   
2. ABS DH36: Has a minimum yield strength of 51,000 psi (355 MPa) and a minimum tensile strength of 71,000 – 90,000 psi (490-620 MPa).
   
   
3. ABS EH36: Has a minimum yield strength of 51,000 psi (355 MPa) and a minimum tensile strength of 71,000 – 90,000 psi (490-620 MPa).
