These grades of steel are intended for structural work where no significant forming or bending must be done. These grades can be bolted, riveted and welded in a full range of structural and fabricated items including bridges, box girders, cranes and other general structural projects.
The grade designations of SANS 50025 / EN10025-2 refer to the minimum yield strength of each
grade for thicknesses less than or equal to 16mm. The steel should be selected in accordance
with the strength requirements as shown in Table 2.The JR, J0 & J2 suffixes refer to different impact requirements. An average impact energy value of 27 Joules must be achieved on full size specimens in the longitudinal direction in all applicable cases. The suffix AR refers to the As-Rolled condition.
If the material is normalised then this will be indicated by a '+N' appearing as a suffix.
The SANS 50025 / EN10025 structural steel grades are all readily weldable by means of the usual metal arc processes.

DIMENSIONS
The plate mill can produce products from 5mm to 100mm thick depending on the grade. See thickness ranges in Plate Price List. The available dimensions for such plates are given in the data sheet: Plate Mill Product Dimensions (file reference A1.3).
The hot strip mill can produce products from 1,6mm to 13,0mm thick depending on the grade. See thickness ranges in Hot Rolled Price List. The dimensions available are given in the data sheet: Hot Strip Mill Product Dimensions (file reference A1.1)
TOLERANCES
Material 6mm and thicker produced at the plate mill is supplied with dimensional tolerances in accordance with EN 10029. If not specified, tolerances will be according to "Class A". Material produced on the hot strip mill is supplied with dimensional tolerances in accordance with EN 10051.
SURFACE INSPECTION
All plates manufactured through the plate mill are inspected and defects repaired in accordance with EN 10163-2: 1991 Class A Subclass 1, unless otherwise agreed.
ULTRASONIC TESTING
If specified at the time of order, ultrasonic testing shall be carried out in thickness ≥6,00mm in accordance with EN 10160.
CERTIFICATION
All material described in this data sheet is supplied with analysis and test certificates.
WELDABILITY
When welding thick plates, reference should be made to BS EN 1011-2:2001 "Welding - Recommendations for welding of metallic materials Part 2: Arc welding of ferritic steels".
The carbon equivalent value (CE) should be calculated from the values of the chemical composition indicated on the test certificates for the plates concerned.
