Claims
- 1. Steel for rails, check rails and railroad rolling components consisting of 0.5 to 0.75% carbon, 0.10 to 0.50% silicon, greater than 0.90 and up to 1.70% manganese, less than 0.025% aluminum, not more than 0.05% phosphorus, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
- 2. Steel for rails, check rails and railroad rolling components consisting of 0.53 to 0.62% carbon, greater than 0.90 and up to 1.1% manganese, less than 0.025% aluminum, 0.8 to 1.3% chromium, 0.1 to 0.6% silicon, from 0.05 to 0.11 each of molybdenum and vanadium, less than 0.02% phosphorus, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
- 3. Rails, check rails and railroad rolling components made from a steel comprising 0.5 to 0.75 % carbon, 0.10 to 0.50% silicon, greater than 0.90 and up to 1.70% manganese, not more than 0.05% phosphorus, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
- 4. Rails, check rails and railroad rolling components made from a steel comprising 0.53 to 0.62% carbon, 0.65 to 1.1% manganese, 0.8 to 1.3% chromium, 0.1 to 0.6% silicon, from 0.05 to 0.11% each of molybdenum and vanadium, less than 0.02% phosphorus, a tellurium content of less than 0.004% and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
- 5. A method of forming rails, check rails and railroad rolling components comprising:
- providing a rolled steel with 0.5 to 0.75% carbon, 0.10 to 0.50% silicon, greater than 0.90 and up to 1.70% manganese, not more than 0.05% phosphorus, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting; and
- forming a rail, check rail, or railroad rolling component from the rolled steel without heat treatment.
- 6. A method of forming rails, check rails and railroad rolling components comprising:
- providing a rolled steel with 0.53 to 0.62% carbon, 0.65 to 1.1% manganese, 0.8 to 1.3% chromium, 0.1 to 0.6% silicon, from 0.05 to 0.11% each of molybdenum and vanadium, less than 0.02% phosphorus, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting; and
- forming a rail, check rail, or railroad rolling component from the rolled steel without heat treatment.
- 7. Rails, check rails and railroad rolling components made from a steel comprising 0.5 to 0.75 % carbon, 0.10 to 0.50% silicon, greater than 0.90 and up to 1.70% manganese, not more than 0.05% phosphorus, 0.01 to 0.25% aluminum, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
- 8. Rails, check rails and railroad rolling components made from a steel comprising 0.53 to 0.62% carbon, 0.65 to 1.1% manganese, 0.8 to 1.3% chromium, 0.1 to 0.6% silicon, from 0.05 to 0.11% each of molybdenum and vanadium, less than 0.02% phosphorus, 0.01 to 0.25% aluminum, a tellurium content of less than 0.004%, and a sulfur content such that the tellurium/sulfur ratio is from 0.1 to 0.6, the balance being iron and impurities resulting from melting.
