Product Description
JIS SCM430 DIN 34CrMo4 1.7220 aisi 4130
seamless alloy steel pipe manufacturer
=>4130 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
Pre hardened and tempered 4130 can be further surface hardened by flame or induction hardening and by nitriding.
=> 4130 is used extensively in most industry sectors for a wide range of applications such as: Adapters, Arbors, Axle Shafts, Bolts, Crankshafts, Connection Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Guide Rods, Hydraulic Shafts & Parts,Lathe Spindles, Logging Parts, Milling Spindles, Motor Shafts, Nuts, Pinch Bars, Pins Various, Pinions, Pump Shafts, Rams, Sockets, Spindles, Sprockets, Studs, Tool Holders, Torsion Bars, Worms etc
Packaging & Delivery
Packaging Details: after 7-10 days after deposit or L/C original of steel pipe
Delivery Detail: standard export packing or as your requirements for steel pipe
