No matter sir...... sir aur ekk chij aap ne Apne video me bataya tha kiii high speed steel ka main constituent ya toh molebadenam ya tungsten hota hai but ye questions wale video me sir Apne main constituent of HSS ka chromium and nickel bataya hai....... i'm confused......
Lightest metal lithium hai ....and heaviest osmium.... Jaldi me ho jata hai kbhi kbhar dost .....next time se bilkul dhayn se ☺and thanks for correcting me ....I appreciate your attention...
nhi ye Jo do type ke hss Hain unke liye hai....aur questions ke perspective me ke agar aapse ye pucha jata hai to venedium ya molibdenum me Jo bhi ho option me wo sahi lagana ....ye isliye Taki aap yad rkh sko easily
wo us particular type ka subdivision hai
alloy steel ke liye
jyada details me ... Inka general composition formula hota hai Fe-C-A Jahan A kisi mixing components ke liye hota hai aur ye depend krta hai ki konsa hss ya alloy steel kis purpose ke liye prepare Kiya gya hai ....Kyu k basic purpose inka high carbon tools means hard metals ko katne k liye cutting tools ke form me develop kiya gya tha. ab depends ki purpose Kya h uske according cromium , tungstum , molybdenum, vanadium ya even Cobalt bhi ho skta hai. jisme 0.60% carbon aur 7% tak ye sab ho skte hai. 1940s me ye basically form kiye gye isi basic purpose k liye .... detail me ye material science me aata hai Jo apne exam k liye nhi hai Kyu k itne time me apn itna hi cover kr skte hain Jo jyada important hai. Baki ummid h smjh aa gya hoga Abhishek aapko
