Abstract
A method for making a strain aging resistant steel comprises adding boron to the steel, wherein substantially all of the boron in the steel forms boron nitride. A method for making steel comprises adding a nitride-forming element to the steel to lower the free nitrogen content of the steel to a free nitrogen content specification. A high-carbon steel contains boron nitride, wherein the free nitrogen content of the steel is less than 80 ppm. A strain aging resistant steel wherein the carbon content of the steel is between about 0.54 percent and about 0.75 percent.
Claims58
A method for making a strain aging resistant steel comprising:
- adding boron to a pre-processed steel to form a resultant steel;
- wherein substantially all of the boron in the resultant steel forms boron nitride;
- and
- wherein the resultant steel is strain aging resistant.
A method for making steel comprising:
- stabilizing free nitrogen in the steel to meet a free nitrogen content specification.
A high-carbon steel manufactured by adding boron to the steel to form boron nitride;
- wherein the free nitrogen content of the steel is less than 80 ppm.
A strain aging resistant steel wherein the carbon content of the steel is between about 0.54 percent and about 0.75 percent.
