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
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.
Yes, it is the element which made steel so brittle
adding chemical fertilizers to the soil
The housewives of America will react with gratitude if you do this. Teflon is very inert, as is stainless steel. But adding teflon to a stainless steel pan gives you the advantage of an easy to clean pan with the durability of stainless.
Adding sulphur to steel makes it easier to machine but only in controlled amounts. Too much sulphur and it become brittle and can crumble.

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
The purpose is to make it sweet.
Steel is made from iron by adding carbon, from 0.2% to 2.14% by weight.
