Advice on material selection, production sequence and heat treatment
For nitriding the correct material selection is of decisive importance as the chemical analysis of the steel and its microstructure affect significantly the nitriding results. The specialists of Härterei Carl Gommann will provide you with appropriate assistance, also taking into account the individual stress on the work piece.
Assistance in planning and construction
Heat treatments are needed in steel components in order to ensure that certain properties are being given for their usage. Here, a variety of problems occur, such as: delay, changes in shape, dimensional changes, volume changes, decarburization, scaling or cracking. During the construction, these problems should be considered through heat treatment based planning. We support you with any questions; please feel free to contact the service department of Härterei Carl Gommann.
Assessment of claims and expert reports
In our laboratory, we have a wide range of test options. As part of our service you may use these in the assessment of materials, their heat treatment and damage cases. Our experts will compile a practically oriented assessment in various fields of heat treatment.
Quality control in our works laboratory
The ongoing monitoring of our heat treatment processes is carried out quickly and reliably in our on-site works laboratory. This leads to continuous quality improvement and process safety.
Development of differentiated nitriding for new materials and special alloys
Nitriding treatments are very complex heat treatments. The various steel grades require individual treatment parameters to achieve optimum properties. In our pilot plant, data for processes for new materials and special alloys can be identified and tested.
Training
Employee training for all industrial areas are of great importance, especially since they also are also required in the context of ISO 9001: 2000, QS 9000 and VDA 6.1.
Härterei Carl Gommann offers training for the different areas of heat treatment of steels and cast iron, where you can set the scope according to your training needs.
Do you have questions about our training program, then please get in touch with us - our team will be available and happy to answer your questions!
Conversion of hardness to hardness and hardness to tensile strength for unalloyed and low-alloy steels and cast steel according to DIN EN ISO 18265 Table A.1 (2.2014) and Shore hardness. Simply select the hardness test method, enter or overwrite the minimum value, and start the comparison.
You can also adjust the value using the slider. If you have any questions, we will be happy to assist you personally.
The values shown in brackets are hardness values that lie outside the defined range of standardized hardness testing methods, but are often used in practice as approximate values.
Vickers hardness testing according to DIN EN ISO 6507-1
Vickers hardness testing is suitable for metallic materials ranging from very low to very high hardness. The method is particularly well-suited for very hard and very small samples.
Brinell hardness testing according to DIN EN ISO 6506-1
Brinell hardness testing is specified for metallic materials using a steel ball as the indenter up to 450 HB. Values above that were determined using a carbide ball.
Rockwell hardness testing according to DIN EN ISO 6508-1
Rockwell hardness testing is applicable to metallic materials whose hardness lies within the following ranges:
HRB: 10 to 100 HRB
HRF: 60 to 100 HRF
HRC: 20 to 70 HRC
HRA: 20 to 95 HRA
HRD: 40 to 77 HRD
HR15N: 70 to 94 HR15N
HR30N: 42 to 86 HR30N
HR45N: 20 to 77 HR45N
