AISI 4130 35CrMo Cold Rolled Precision Steel Tube Seamless for Precision Engineering
AISI4130 and AISI4140 are all belong to "ALLOY STEEL" material,the content of Cr and Mo is much higher than Carbon Steel material.And they have perfect performance during impact.
So they have widely use in the gear for locomotive traction,turbocharger transmission gear,pressure vessel gear,rear axle,connecting rods and spring clips with heavily loaded.
Cold Rolled High Precision Seamless Steel Pipes have bright,smooth and oil-dipped surface.So it can save energy during the maching process.
