phosphorous might add increased atmospheric corrosion resistance, however, it may be more prone to stress corrosion cracking because of the increased hardness. In general phosphorous adds strength, but reduces ductility / makes the steel more brittle; in amounts less than 0.30% it has little effect on the weldability of low-carbon steel.
Phosphorus is not naturally occurring in its pure form; it is typically found in compounds. The most common form of phosphorus is white phosphorus, which is waxy and can be easily broken into pieces. However, red phosphorus is more stable and less brittle.

phosphorus-doped silicon ( n-type semiconductor) can be be produced by adding phosphorus to silicon to obtain a mixture, then heating and melting the obtained mixture. Or add phosphorus to already melted silicon.
Phosphorus is commonly used to make fertilizers, detergents, and certain types of fireworks. It is also used in the production of matches, steel, and certain types of chemicals.
Inorganic phosphorus in rocks can be converted to organic forms through weathering processes that release phosphorus into the soil, making it available for uptake by plants. This conversion can also be facilitated by the action of microbial and fungal populations in the soil that transform inorganic phosphorus into organic compounds that plants can use. Additionally, adding organic matter or organic fertilizers to the soil can help increase the availability of organic phosphorus for plant uptake.
Adding sulphur to steel makes it easier to machine but only in controlled amounts. Too much sulphur and it become brittle and can crumble.

limestone is used to reduce the phosphurus
Phosphorus is not naturally occurring in its pure form; it is typically found in compounds. The most common form of phosphorus is white phosphorus, which is waxy and can be easily broken into pieces. However, red phosphorus is more stable and less brittle.
Steel is stronger than concrete. By adding some reinforcement in the compression zone of a beam, it's bending strength can be increased without increasing the size of the beam. The steel increases the compression strength, while the concrete prevents the slender steel bars from buckling.
The steel having this defect cracks when being worked in cold state. This defect is due to presence of excess of phosphorus
You can obtain phosphorus for plants effectively by using phosphorus-rich fertilizers, such as bone meal or rock phosphate, or by adding compost or manure to the soil. Additionally, you can plant phosphorus-accumulating cover crops or use mycorrhizal fungi to help plants absorb phosphorus more efficiently.
You can make phosphorus available to plants by using phosphorus-rich fertilizers, such as bone meal or rock phosphate, or by adding compost or manure to the soil. Additionally, you can promote the growth of phosphorus-fixing bacteria in the soil to help plants access this essential nutrient.
The purpose is to make it sweet.
Steel is made from iron by adding carbon, from 0.2% to 2.14% by weight.
