Pine forest, mainly, is used in metallurgy, for example, to increase hardness steel drills of production and boric acid and element pine forest because it absorbs ability to neutrons, strongly. Pine forest at high temperatures is especially live, thus, it was used for the metallurgical recipient of heat treatment, welding iron the warm process, the increased rough alloyed steel of high temperature, pine forest also is used in nuclear reactors and high-temperature technology. Borsoderzhashchy steel of a rod and a strip is widely used in quality прутов control in a nuclear reactor. Because of the nature of pine forest has low density, high force and a high melting point, it can be used to make some structural materials in the rocket rocket. Compositions of pine forest in agriculture, medicine, the glass industry is widely used. Therefore, development of resources of pine forest, use, for development of the modern industry has more and more an important role. Pine forest - the nonmetallic element, pine forest in the nature, mainly, exist in boric acid and борате, element pine forest was not found. Addition of a small amount of a powder of pine forest in steel can increase steel hardenability, it is pine forest a unique role. Pine forest can improve also mechanical properties of steel and improved weldability. Pine forest in steel, mainly, exists in firm solution, also can create pine forest nitride, an oxide of pine forest and iron carbonaceous борид pine forest.
About a pine forest form in the steel, nevertheless any incorporated division. The metal school is divided into effective pine forest and inefficient pine forest; the metallography was divided into pine forest and бориды; firm thawing in acidsoluble from pine forest and acid insoluble pine forest the chemical analysis. Some contact among the various.
