There are Four Kind of CR (Cold Rolled Steel Coils)

• Commercial Steel ( - JIS : SPCC, SPCD, SPCE - ASTM : A366-91, A619, A620)
  
  
  
  • CR Steel is generally used in the manufacturing of Refrigerator doors and body, drums for different sizes, furniture, automobile parts including (quarters, bodies, pans, houses, roofs, fenders, hoods etc).
  
  
  
  


• Structural Steel (ASTM : A611-91A)
  
  
  
  • This Type of Cold Rolled Steel is used for Structures and need special strength
  
  
  
  


• For Porcelain Enamellings (JIS : SPP) & (ASTM : A424-TYEP1)
  
  
  
  • For any deep drawing work such as Kitchen utensils, bathtubs, spinning tubs and ordinary home appliances.
  
  
  
  


• High Tensile- Strength Steel ( Commercial : CHSP45C/60C - Drawing : CHSP35R/40R/45R
  
  
  
  • Deep Drawing : CHSP35E/40E/45E - Extra Deep Drawing Quality : CHSP35ES/40ES - TRIP-Type : CHSP60TR/80TR/100TR - Bake Hardening : CHSP28EB-E/35EB/40EB
  
  
  
  


• This is further divided in four classes (1)- Commercial (2)- Drawing, (3) - Deep Drawing, (4) - TRIP


• High Tensile Strength Commercial Cold Rolled Steel is used mostly and commonly in rail levers, automobile seats and parking brakes. For Drawings standard is usually used for Center floors, brackets, major outer panels of automobile and alternatively the TRIP Quality material is also used in automobiles impact bars, doors and bumpers as well.

Hot-Rolled Steel for General Structures
