Steel Details and Making Process Information
Steel Metal Details

Steel mukhtalif metals ka mixture hai jisy alloy kaha jata hai lekin is mein ziyada tar Iron shamil hota hai. Steel iron sey ziyada sakht aur taqatwar hota hai. Steels aksar iron alloys hote hain jo 0.02% sey 1.7% percent Carbon weight hote hain. Alloys jin mein bohat carbon hota hai unhen cast iron kaha jata hai. Kuch naye steels aisy hain jin mein carbon ko dusre alloying materials sey replace kiya jata hai.

Making of Steel


Steel ki aik lambi history hai India aur Sri Lanka mein rehne walay log aaj sey 2500 saal pehle steel ki choti amounts banate they. Ye bohat mehnga tha aur aksar swords(talwar) knives (churi) mein istemal hota tha. Middle Ages mein steel ko sirf choti aur kam amount mein banaya ja sakta tha kyon ki isko processes karne mein bohat waqt lagta tha. Waqt ke sath sath bohat tabdeeliyan ayi steel banane mein bohat sari tabdeliyan ki gayi 1610 mein England mein steel banana shuru ho gaya aur jis tarah ye banta tha steel banane ka tarika behtar hua aur uski qeemat aglay 100 saalon mein kam ho gayi. Sasta steel England mein industrial revolution ke liye kafi madad gar sabit hua. Pehla industrial converter metallurgy sasta steel banane ke liye Bessemer converter tha.

Steel Kaise Banta Hai


Aaj ke daur mein steel ko banane ka sab sey aam tarika basic-oxygen process hai. Converter aik bara turnip-shaped vessel hota hai. Liquid raw iron jisey pig iron kaha jata hai us mein dala jata hai aur kuch scrap metal heat ko balance rakhne ke liye shamil kiya jata hai. Oxygen ko iron par phenk diya jata hai. Oxygen extra carbon aur dusri impurities ko jala deti hai. Kafi carbon ko shamil kar liya jata hai takay contents ko marzi ke mutabiq banaya ja sake. Phir liquid steel ko dala jata hai ye molds mein dala jata hai aur sheets, slabs, beams aur dusri naam nihad long products mein bhi dala jata hai jaise Railway Tracks. Kuch khaas steels electric arc furnaces mein bante hain.

Steel ziyad tar machines banati aur ye bohat bari buildings jinhen steel mills kaha jata hai wahan par banta hai. Steel bohat cheap metal hai aur iske zariye bohat sari cheezain banai ja sakti hain. Steel ko buildings aur bridges banane ke liye istemal kiya jata hai aur har kisam ki machines mein istemal kiya jata hai. Aaj k daur mein banne wali taqreban har Ships aur Cars steel se banti hain.

Jab koi steel object purana ho jaye ya phir toot aur ya repair na kiya ja sake to isay scrap kaha jata hai. Scrap ko dobara pighla kar isko reshape karke iska koi bhi naya object banaya ja sakta hai. Steel recyclable material hai jis mein same steel ko use aur reuse kiya jata hai.

Iron aur Steel Ki Chemistry


Steel aik metal alloy hai jis mein iron aur aksar kuch Carbon shamil hota hai. Har metal atoms ka bana hota jo bohat chote parts mein hota hai. Kuch atoms ko ikatha rakha jata hai jiski wajah sey kuch solid materials sakht ban jate hain. Kuch pure iron aur kuch steel sey naram hote hain kyon ki Atoms aik dusre par slip kar sakte hain. Agar dusre atoms jaise carbon shamil kiye jate hai wo iron atoms sey mukhtalif hote hain aur iron atoms ko sliding apart bohat asani sey krete hain. Jiski wajah sey metal taqatwar aur sakht banta hai. Carbon ki amount ko change karne ke liye dusre atoms steel ke sath mix kiye jate hai jo cheezain intersteing aur metal sey useful hoti hain inhen steel ki properties kaha jata hai. Kuch properties darj zail hain:-

  • Is it magnetic, a magnet can pick it up
  • Hardness
  • Ductility: can it be made into thin wires
  • Strength
  • Will it rust (or corrode)
  • How easily it bends

Steel pure iron sey ziyada carbon ke sath sakht aur taqatwar hota hai lekin ye bohat asani sey toot bhi jata hai.

Different Types of Steel


Steel ki bohat sari iqsam hain jin mein sey kuch iqsam darj zail hain:

Stainless Steel :- Stainless steel ko aam taur par zang nahi lagta aur isay stain isliye kaha jata hai kyon ki zang ka rang red hota hai.

Carbon Steel :- Carbon steel, steel ki sab sey aam type hai lekin is par paint karna ya phir isko cover karna zarori hota hai agar aisa na kiya jaye to is par zang lag jata hai.

Galvanized Steel :- Galvanized steel aisa steel hota hai jisy zang sey bachane ke liye Zinc sey cover kiya jata hai.

Uses of Steel


Steel se banne wali bohat sari cheezain hain ye sab sey aam aur useful metal hai. Aisi bohat sari cheezain hain jo past mein iron sey banti thi lekin ab wo steel sey banai jati hain jin mein se kuch darj zail hain :-

  • Cutlery and knives
  • Bridges
  • Buildings
  • Tools
  • Motors and engines
  • Machines
  • Hulls of ships and large boats
  • Car and train bodies
  • Rulers
  • Major appliances
  • Wires
  • Rails for trains
  • Bars for making reinforced concrete

Airplanes aur Rockets steel ke nahin bane hote balkay Aluminium ke bane hote hain. Agar aap ko meri ye post achi lagi hai to neeche thanks box par click kar dain aur iss informative post ko Share ke button par click karke facebook ya twitter par apne friends ke sath share bhi karen.
