ABS Grade AH36, DH36, EH36 Z35

Download data sheet

General Product Description

ABS Grades AH36, DH36, and EH36 Z35 are "Z" quality, higher-strength structural steels with a minimum specified yield strength of 51 ksi and specified minimum Charpy V-notch impact toughness properties. The Z35 quality steel has a minimum specified average value for reduction of area in through thickness tensile testing of 35%.

Applications

Typical applications include shipbuilding and mobile offshore drilling units and structural details for which greater resistance to lamellar tearing is desired

Mechanical Properties

Tensile testing is performed in the transverse direction. When "Z" quality steel is specified, through-thickness tension testing is performed in accordance with ABS Rules.

1) Specimen orientation at the option of the manufacturer unless otherwise specified in the order.

No more than one value below the specified miniminum average energy but no less than 70% of the specfied minimum average energy value.

Minimum average energy for full-size specimens. Refer to ABS Rules for sub-size specimen energy requirements.
