What are the alloying elements in High Speed Steel
Tungston, Chromium , Molybdenium and vanadium
What will be the effect in the following material alloyed with steel composition?
1.Phosphorous 2. Sulphur
Both usable in alloying of Tool steel that make red short effect during metal cutting. These are used to improve machinability in Steel used a little amount of 1 percent to carbon steel inorder to have good machinability.
How silicon improve properties of steel
It is a deoxidizing agent and during melting of steel it is used . So all steel will have little quantity in it.
It improve magnetic and electrical property .
It increases harden ability in steel.
Mention various types of Tool Steels
Hot working Tool steel
High-Speed Tool Steel
Cold working Tool Steel
Shock resisting Tool Steel
Mild Steel
Low alloy tool steel
Water hardened Tool Steel
Normal Steel
Why Chromium and Molybdenum added in low alloy steel
Chromium increases and improves wear resistance and high temperature strength and improves hardenability.
Molybdenum increase hardenability of steel and increases red hardness and improves wear resistance . It increases creep strength of low alloy carbon steel in high temperature.
Where tool steels are used
It is used to make cutting tools , forging tools and die etc.
Write the constituent of HSS
18 - 4 – 1 of High speed Steel contains 18% Carbon 4% chromium 1% Vanadium
