low alloy high strength steel plate astm a633gr a gr b gr d
A633 is high-strength low alloy structural steel plate with high notch toughness. Kloeckner Metals routinely stocks A633 nationwide.
The ASTM A633 specification is the Standard Specification for Normalized High-Strength Low-Alloy Structural Steel Plates when superior notch toughness is needed at low temperatures. Grades C is available up to 4" in thickness and Grade E is available up to 6" in thickness. Typical applications are utility poles as plates, offshore platforms, construction equipment frames, electric shovel dipper Standard Specification for Normalized High-Strength Low 1.1 This specification covers normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. 1.2 This material is particularly suited for service at low ambient temperatures of 50°F [45°C] and higher where notch toughness better than that expected in as-rolled material of a comparable strength
A633Gr.A steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A633Gr.A steel plate is under ASTM-SAE standard equivalent to DIN:A633Gr.A,which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A633Gr.A is 370 to 510MPa
