Ferro boron
As we all know, boron is a non-metallic element with a proton number of 5 and an atomic weight of 12. Its solubility in steel is very small, but it has a great influence on the hardness of steel. Boron can delay the formation of ferrite and pearlite.
effect
1. Ferro boron can help the formation of martensite during rapid quenching. For example, if the content of 0.0005%-0.008% boron is added to automobile fasteners, the quenching and tempering hardness of many steel grades is significantly improved, and the use of boron to replace precious and rare elements can receive better economic benefits. As far as boron is concerned, it has no obvious effect on the cold working of steel, but it is more obvious during heat treatment. Carbon boron has the characteristics of high toughness, strong plasticity, low tempering temperature and high strength, which is very suitable for the production of high-strength fasteners.
2. Adding ferro boron to high-quality alloys can partially replace chromium, nickel, molybdenum and other alloy elements without reducing the performance of steel products.
3. Adding ferro boron to the cold-rolled base material produced by continuous casting and rolling of thin slabs can reduce the yield strength of hot-rolled strip, reduce the rolling force of cold-rolling, increase the life of the rolls, and reduce the energy consumption.
4. Adding ferro boron to non-oriented silicon steel can improve the magnetic properties of silicon steel sheets, reduce magnetic aging, reduce iron loss and improve surface quality.
5. The tensile strength of high-strength steel (petroleum pipeline steel) can be evaluated by solid solution boron in the steel. With the increase of the solid solution boron content in the steel, the tensile strength increases linearly, and the increase in strength will increase with the cooling rate after rolling. and significantly improved.
