Rail Products Rails The majority of rails manufactured by OneSteel in Whyalla are produced to AS 1085.1 Railway Track Material Part 1 — Steel Rails.

Depth of heat treatment and hardness gradient as per AS 1085.1-2002 Dimensions (mm) a. 15 Min. 23 Max. Dimensions (mm) b. 20 Min. 35 Max. for 50 kg Rail Dimensions (mm) b. 25 Min. 40 Max. for 60 kg and 68 kg Rail

Table 38 page 28 lists the various rail sections produced at Whyalla together with the conforming standard.

For dimensional details see Table 31 page 25.

Length — standard length available for AS68kg rail is 25m, for all other rails standard lengths are 12.19 m, 13.72 m and 27.5 m.

Drilling — rails can be supplied drilled or undrilled.

Head Hardened Rails Where rail wear, plastic flow of the rail head, corrugation or rail fatigue defects are reducing rail life it is recommended that OneSteel head hardened rail be specified. Available test data indicate a doubling of rail life will occur. Head hardened rail is available in 50 kg/m, 60 kg/m and 68 kg/m sizes.

Some situations where heavier and more expensive crane rail is specified can also be handled with high strength head hardened rail.

For further information on rail products contact:

* 300PLUS replaced Grade 250 as the base grade for these sections in 1994.

300PLUS hot rolled sections are produced to exceed the minimum requirements of AS/NZS 3679.1-300.

Notes 1. For 300PLUS sections the tensile strength (fu) is 440 MPa. 2.

For Grade 350 sections the tensile strength (fu) is 480 MPa.

* 300PLUS replaced Grade 250 as the base grade for these sections in 1994.

300PLUS hot rolled sections are produced to exceed the minimum requirements of AS/NZS 3679.1-300.

Notes 1. For 300PLUS sections the tensile strength (fu) is 440 MPa. 2.

For Grade 350 sections the tensile strength (fu) is 480 MPa.

*300PLUS replaced Grade 250 as the base grade for 125x125x8 equal angles and larger in 1994.

300PLUS replaced Grade 250 as the base grade for 100x100x12 equal angles and smaller in 1997.

300PLUS hot rolled sections are produced to exceed the minimum requirements of AS/NZS 3679.1-300.

Notes 1. For 300PLUS sections the tensile strength (fu) is 440 MPa. 2. For Grade 350 sections the tensile strength (fu) is 480 MPa.

Notes (apply to tables 36 and 37) 1. For a section, the term ‘thickness’ refers to the nominal thickness of the part from which the sample is taken.

2. So is the cross-sectional area of the test piece before testing.

3. For precise details of properties reference should be made to the latest edition of AS/NZS 3679.1:1996 or the latest OneSteel specification.

4. 300PLUS® steel is produced to exceed the latest requirements for grade 300 in AS/NZS 3679.1.

*The recommendations are based on the criterion that, at the maximum dimensions, a hardness of 50 HRC can be achieved in the centre of the quenched section.

The actual properties obtained are dependent on both grade and heat treatment process control. As OneSteel 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.
