A-633 Normalized High-Strength Low-Alloy, HSLA, Structural Steel Plates

Description

This specification covers normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. This material is suited for low ambient temperatures where the desired notch toughness is better than that expected in as-rolled materials of comparable strength level. The material shall have fine austenitic grain size and shall be normalized by heat treatment. Its chemical composition shall be determined by heat analysis. Tension tests shall also be done

Applications

It is suited for service at low ambient temperatures of –50°F or higher where notch toughness better than expected is desired. utility pole base plates, offshore oil and gas platforms, construction equipment frames, electric shovel dipper handles and suspension components

Specifications

A-633 Normalized High-Strength Low-Alloy, HSLA, Structural Steel Plates

Four grades, designated Grades A, C, D, and E (essentially former Specification A633 without a grade designation) are covered by this specification. Grade A provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive. Grade E provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
