Average Brinell Hardness Numbers (BHNs) for Abrasion Resistant Steel Grades [4] Grade BHN AR200 & AR235: 180-260 AR400: 360-440 AR450: 430-480 AR500: 460-544 AR600 ...
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
On certified steels, the plates are marked with the grade and a preceding "AB/", e.g. AB/A etc. [3] Yield point for all ordinary-strength ABS steels is specified as 34,000 psi (235 MPa ), except for ABS A in thicknesses of greater than 1 inch (25 mm) which has yield strength of 32,000 psi (225 MPa), and cold flange rolled sections, which have ...
