October 2019 1 1 2 INTRODUCTION Foreword This edition of Liberty Steel’s Hot Rolled and Structural Steel Product Catalogue incorporates the following changes from the previous edition. • The depths and widths of Universal Beams (UBs) and Columns (UCs) were previously provided to three significant figures. For consistency with AS/NZS 3679.1 Structural Steel – Hot rolled bars and sections, these measurements are now provided to one decimal place. The dimensions for UBs and UCs were converted from imperial to metric units of measure in the mid 1970s and resulted in dimensions that were not whole millimetres. Until this edition they were rounded to three significant figures. The other sections in the Catalogue are metric and therefore in whole millimetres. The section properties for all sections in this version and the previous versions have used depths and widths correct to one decimal place to calculate the tabulated values presented to three significant figures. These values are unchanged from the previous edition. • The inclusion of tolerance tables for each of the products listed. These values are consistent with AS/NZS 3679.1. • The inclusion of tables providing the allowable camber and sweep of sections consistent with AS/NZS 3679.1.

The use of sulfide modification steel making techniques for these grades is permitted. 2. Grain refining elements, i.e. aluminium and titanium, may be added, provided that the total content does not exceed 0.15%. Limits are for total or soluble aluminium. 3. The following elements may be present to the limits stated, subject to a maximum total of 1.00%: (a) Copper 0.50% (b) Nickel 0.50% (c) Chromium 0.30% (d) Molybdenum 0.10% 4.

The actual properties obtained are dependent on both grade and heat treatment process control. As Liberty Steel has no control over the springmakers’ heat treatment process, the above recommendations cannot be guaranteed. However, springmakers with efficient heat treatment facilities will be able to achieve a hardness value of 50 HRC as recommended. 30 HRSSP 9th Ed. October 2019 1.00 P S Min. Max. Min. * 0.040 * Min.
