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.
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 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.
Notes1. For 300PLUS sections the tensile strength (f
u
) is 440 MPa.
2. For Grade 350 sections the tensile strength (f
u
) is 480 MPa.

* 300PLUS replaced Grade 250 as the base grade for 150x90x8 unequal angles and larger in 1994.
300PLUS replaced Grade 250 as the base grade for 125x75x12 unequal 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 (f
u
) is 440 MPa.
2.For Grade 350 sections the tensile strength (f
u
) is 480 MPa.

*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.
