A633 Gr.A Steel Description

A633 Grade A carbon and low alloy steel plate, A633 GrA low alloy structural steel plate under ASTM A633/A633M standard, A633 GrA is a high-strength structural steel, ideal for welding, riveting or bolting. There are four grades under the ASTM A633/A633M standard: A, C, D and E. Namely A633A, A633B, A633C, A633D, is the abbreviation of A633GrA, A633GrC, A633GrD, A633GrE.

A633 GrA high-strength structural steel is particularly suitable for use in low temperature environments ≥ -50°F [-45°C] compared to rolled materials of similar strength, because this environment requires steel sheets to have better notch toughness than those of similar strength. Strength grade of rolled steel sheet. Charpy testing requirements for specific regions and climates may be required; multiple certifications to API or ABS specifications may be obtained in mill test reports, but compliance to ASTM A633 is guaranteed.

ASTM A633 GrA low alloy structural steel plate can be used in the manufacture of workshops, general buildings and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various Such as cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.

BBN Steel can provide cutting and processing varieties covering ordinary plates, alloy plates, container plates, high-strength plates and other steel plates, with a cutting thickness of 6mm-400mm. The center has large-scale CNC flame cutting machine, plasma cutting machine, large-scale hydraulic shearing machine and other steel plate cutting and processing equipment, as well as first-class technical personnel and after-sales service system. Realize one-stop service from product drawings, steel plate procurement → steel plate cutting → steel plate processing → steel plate distribution, so as to maximize the saving of manpower and material resources for customers, realize the purpose of zero inventory of raw materials, reduce capital backlog and reduce equipment investment.

Heat treated : 1317°C - 1343°C
