Schulz Hartchrom GmbH

Hard chromium is a surface protection that distinguishes itself with the following properties:

• high degree of hardness (800 – 1100 HV)
• good wear and tear resistance
• good corrosion resistance
• high temperature resistance (up to 400°C)
• low adhesion tendency

Contrary to bright chrome, hard chrome denotes a significantly thicker chrome coating that can be applied up to a strength of several millimetres on the basic material depending on the application.
Hard chromium plating realises a substantially longer service life of wear and tear parts, thus guaranteeing error-free machine running time.

Hard chromium plating of new parts in our in-house production facilities (raw material -> machining -> cylindrical grinding -> hard chromium plating -> belt finish) is our strength.

Our services include corrosion-resistant, microcrack hard chromium plating of piston rods and pipes in a dimension range from 20-100 mm diameter and lengths from 5,000 to 6,800 mm.
Small and large series can be processed in batch sizes of 500 m up to 50.000 m/a in layer strengths from 20 to 40 µm.

Max. processing size:
Length:	6,800 mm
Ų:	100 mm
Weight:	400kg
Basic materials:	Steel, stainless steel

Over 50 years of experience in the field of hard chromium plating, expert competence as well as individual consulting and short delivery times turned us into one of the leading providers of this surface processing technology.
