Medium and High Carbon Steel

Steel Grade:

75Cr1    , 50Mn2V ,    30CrMo,   SK85  , 16MnCr5 , 30MnB5,   10SiMn2  , 28Mn2, 38MnB5 ,   20Mn2-50Mn2 , 51CrV4 ,  

 SCM 415-445,    20#-85#  , 20Mn-70Mn, T7  , T8  , T9  ,           SAE1020-1086 , S20C-58C , SK60-95 , C20-60, C55S-95S

 

1.The medium and high carbon steel (0.25-0.90%) is of full specification with high strength ,high toughness ,high hardenability and high hard wear -resistance ,which we widely used in saw blade (stone ,metallurgy and woodworking ),automotive parts (disk spring ),safety, hose clamp ,seat gear),cutter ,tool and high strength binding ,etc. The sheet thickness covers 1.6mm-20 with width 980-2050mm ;

 

2.The medium and high carbon steel from SYI steel with application of saw blade basement guarantee that the Rockwell hardness (HRC)is between 18-26,So that the turn-down edge due to over softness shall not be generated ,tearing due to hard is also impossible during the processing of saw blade basement .The product performs good plasticity ,which used for automotive or tractor clutch ,high reduction can be implemented during cold rolling process ;

3.With good profile and high dimension accuracy ,the product higher than 3.9mm in thickness can be decoiled  in the most advanced domestic cut-to-length line ,which guarantee good flatness .i.e. unflatness < 4mm/m .The unflatness of the product with thickness lower than 3mm can be guaranteed as < 15mm/m after standard decoiling through finishing ;

4.The ultra-thin 1.6mm and ultra-wide 2050mm hot rolled wide strip or sheet can be supplied ;

 

5.The midium and high carbon steel can be batc annealed by coil or roller hearth annealed by sheet ;
