Method for making strain aging resistant steel |
摘要 |
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. |
