EN13674-1 60E2 rail is used for special state railway line, it is near 60E1, but has a little different, we can produce it by order, the MOQ should more than 1000 tons.
Usually these type of rail will be used for state railway line, it needs different hardness and different length, we can produce all of it as your requirement.
We can design railroad line as your requirement, also can build small type mining railway line and crane moving line, also can supply the all workable fasteners.
The quality of our products all be very good, we can accept the payment term of L/C and any third party inspection.
Please refer below specification to tell us your request:
Standard EN 13674 – 1:2003 consists of two main parts:
− qualification test and
− acceptance tests
Qualification tests are some other tests that were previously carried out, as for example, fracture toughness. Acceptance tests characterize the properties of the prescribed tests, which ensure production of high quality rails, and testing requirements of railway administration.
Quality of rails is based on measured values of hardness, by which they introduced new labels for steel rails.
Qualification testing must be conducted at least one in five years and the major
changes in technology, production rails. Additional testing residual stresses are carried
out on all types of steel rails every two years maximum, provided that the longitudinal
strain rate in the rails can amount to up to 250 MPa.
The prescribed qualifying examination is the following:
− fracture toughness
− fatigue crack growth rate
− fatigue testing
− residual stress in rail foot
− variation of centre line
− tensile strength and elongation
− other qualification requirements
Within acceptance testing is carried out a series of laboratory tests such as:
− chemical composition (the maximum content of the following elements: H, O, Al, V, N and oligo elements)
− microstructure (increasing x 500)
− degree of decarburizing charred layer (allowed up to 0.25 mm)
− purity of steel (especially the presence of oxide)
− macrostructure (Baumann test)
− tensile strength
Other acceptance testing rails are:
− dimension tolerances
− criteria (control template)
− inspection requirements / tolerances for to internal quality and surface quality
Internal state is examined ultrasound in a continuous process control, and includes at least 70% of the head and at least 60% web.
– Standard of UIC 860 V: 1996 – prescribed four types pearlite steel rails in the range of tensile strength from 700 to 1300 MPa.
– Standard EN 13674 – 2003, provides seven types pearlite steel hardness in the range 200 to 390 HBV, types steel in accordance with EN 13674, based on the values of hardness (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
