SK3 steel,SK3 steel materials,AISI SK3 steel plate properties

SK3 steel plate
Steel Category: Forged carbon tool Steel
Steel standard:AISI
Steel grade:AISI SK3
Dimension: Thickness 5-300mm, Width 1500-3500mm, Length 3000-12000mm
Application: The strength and abrasion resistance of SK3 is higher than SK6 , but hot hardness is relatively low. Suitable for manufacturing lower cutting condition and higher wear resistance , and SK3 is not affected by suddenly and violent vibration, SK3 can be used to manufacture all kinds of tools with a certain toughness and the sharp edge, such as tool, cutter, drill bit, cutter, low accuracy and shape simple measuring equipment (such as card board, etc.), also can be used as wear parts withstanding larger impact.
