  1. All steel parts having a hardness of Rockwell C40 (180,000 PSI) and higher must be baked at 375 degrees F, plus or minus 25 degrees F for 3 hours minimum after plating to release hydrogen embrittlement.  I would suggest if you don't know the hardness of your parts being plated you can safely bake them in a home oven. Preheat your oven to 375 F then put your plated parts in. The plating should not blister if the electro-plating process was done correctly. Plated parts do not have to baked in between plating steps but I would recommend them being baked within 24 to 48 hours after plating.  In the Industry, Auto, Areo and the like most materials designed for decorative plating ( Cu. Ni. Cr. ) are of materials that don't need hydrogen embrittlement release. 

  2. We offer black oxide on stainless steel using the old school mixtures. Stainless steel is not easy to blacken even with the correct chemisty because of the wide range of stainless alloys. we've been processing black oxide on stainless for over 45 years and in some cases we will adjust the oxide mixture to accomade the alloy composition.

  3. Hi Curt,  Both processes will model the surface finish of your parts and the longer they are plated the brighter they will become especially the sulfate process, if your looking for a semi bright finish or a brush finish make sure your molding is preped with that finish before plating, If you have a sample of the finish and have a good plater they might have the capabiliy to creat your final finish on the nickel after the plating process.

  4. Electoless Nickel has its advantages with precsion coating thickness but doesn't meet the brightness and plating thickness applied with the sulfate chloride high speed plating process. To apply .002 to .003 thousands of nickel with the Electroless process takes about 2 1/2 hours where the sulfate process would apply .020 thickness in that time.

  5. Yes chrome plating over nickel was created in 1924 and preserved the nickel shine. Flash chrome thichness over bright work averages about 10 to 20 microns depending which plating shop you use. Before 1924 all the automotive nickel  plating had to be polished by hand on a regular bases to look pretty.  The great fact with the high speed nickel plating processes today is chemisty, with brighters and levelers, the nickel bridges and can be applied very thick which covers small blemishes that might not be able to be removed in the grinding and polishing before plating.

  6. jpage, So true large plating shop don't like doing small auto plating jobs so they mix it in with large industrial work to off set the cost. Speaking from experience and owning a large industrial plating shop for 42 years and being a car enthusiast I started Old School Plating to cater to the classic & antique auto field. We process each job seperate with the best of care. Having my father's plating experience and plating bibles we still offer the OEM finishes from Yester-year.

  7. Hi ,  We specialize in OEM plating finishes for under the hood & chassis such as cyanide cadmium, zinc black phosphate, black oxide and chromates black gold and clear.  We don't do bright chrome but would reccommend Librandis Plating in Harrisburg Pa.  Thanks Steve

  8. Hi,  We at Old School Plating offer OEM plating standards from yester-year.


    Cyanide Cadmium

    Chromates, Gold, Black, Clear

    Zinc Black Phosphate

    Black Oxide

    Zinc Plating

    Re-surfacing & Baking



  9. Hydrogen embrittlement is formed in all electroplating processes ( zinc or Cad ) but it does not effect ferrous materials under a hardness of 40 rockwell.  On steel parts electroplating 40 rockwell or harder the hydrogen can be remove with a bake out at 375 degree F for 3 hours with in 24 hours of the plating process.
