General Product Description

ASTM A633 Grade E is a normalized high-strength low-alloy structural steel plate for welded, riveted or bolted construction requiring superior notch toughness performance at low ambient temperatures. A633 Grade E has minimum yield strength of 60 ksi [415 MPa] and may be ordered with supplemental Charpy V-notch impact test requirements.

Applications

Typical applications for A633 Grade E include utility pole base plates, offshore platforms, construction equipment frames, electric shovel dipper handles and suspension components.

Tolerances

Thickness, width, and length tolerances for A633 Grade E steel plate are in accordance with the requirements of ASTM A6. The flatness tolerance for as supplied product is ½ ASTM A6.

Delivery Conditions

ASTM A633 Grade E is supplied in the normalized condition.

Formability properties

A633 Grade E material exhibits excellent cold forming characteristics. Shear burrs and heat-affected zones of thermal cut edges on or near the bend axis as well as sharp corners on edges and on gas cut or punched holes located on or adjacent to the bend axis should be removed by grinding prior cold forming. The following recommended minimum inside bend radius, R, and die width opening, W, as a function of bending orientation are provided:

Weldability

Welding of A633 Grade E shall be performed in accordance with the applicable welding code. In the absence of a specified welding code, the following suggested minimum preheat and interpass temperatures and welding consumables are provided. Special welding consumables and welding procedures may be required to match the base metal toughness. Low hydrogen practices are strongly recommended, including the removal of surface moisture.
