carbon steels are steels which contain upto 2% carbon and some other trace elements such as silicon, manganese etc., Tool steels have greater amount of alloying than the alloy steels of iron. alloying elemnts include chromium, tungsten, molybdenum, carbon, vanadium, nitrogen in the form of nitrides, manganese, silicon, cobalt. These two mainly differ in the pattern in which they are manufactured. tool steels are manufactured from electric furnace techniques where as most carbon steels are manufactured from conventional melting processes. This is done to exhibit good alloy characteristics and impart greater refined structure which cannot be obtained from the conventional say a cuppola furnace or a bessemer furnace.
steels
Silicon is used as a deoxidising (killing) agent in the melting of steel, as a result, most steels contain a small percentage of silicon. Silicon contributes to hardening of the ferritic phase in steels and for this reason silicon killed steels are somewhat harder and stiffer than aluminium killed steels.
Steels resistant to climate change.
Gouging is the process of removing unwanted materials.It is done by means of material is locally heated and molten metal is ejected out or blow up.
No.You should not do that because the welding heat leads to over tempering of P91 which reduces the toughness and ductility...

The most significant cause of the 1979 energy crisis in America was price gouging. The price gouging was done by the oil companies especially OPEC.

annealing for steels
Yes, price gouging creates a deadweight loss.
SA means Standard America
P 91 is a martensitic steel.
Steel is annealed to bring it to a specific level of hardness, reducing its brittleness after heat treatment or forging.
