Induction Hardened Chrome Plated Bars

Induction Hardened Chrome Plated

With two induction heat-treating lines for bars and tubes, we can easily handle round products to 12” diameter x 75’ long.  We produce standard or deep case depths, and we can selectively harden bars or tubes where needed instead of the full length.  This will ensure areas that do not require hardening are easier to machine, saving you time and money.  We will also be happy to process your material – just call our sales department for a quote!  Northlake can provide chrome and nickel plating as well as special cladding for better corrosion and abrasion resistance – the finishing touches to hydraulic cylinder rods and other shafting, bar, and tubing products. 

Induction Hardened + Chrome plated bar specifications:

  • Diameters: 1″ Rd thru 12″ Rd.
  • Surface hardness up to 65 Rc, based on grade and product.
  • Deep case available to depths of .250” and beyond.
  • Selective hardening available where we can leave sections or ends of the bars “soft” for simpler machining down the road.
  • Bars are precision straightened after induction hardening.
  • Lengths: to 40′ and beyond upon request.
  • Steel Grades: 10V45 (75,000 PSI min yield strength). 1045 (50,000 PSI min yield strength). 4140HT (100,000 PSI yield strength is typical).
  • Chrome thickness: .001″ min per side is typical.
  • Surface finish: 12 Ra max. Additional parameters can be achieved upon request (Rz, Rpk, Rvk, Rmr, etc).
  • Straightness: .001″ to .002″ per foot.
