steel hardness conversion

Steel Hardness ConversionBelow is a conversion table for the hardness of the steel.

The values listed are for reference only. There are some parameters that could change the

conversion. For example, the HV is only testing on a focused small spot, where the HRC/HB would

have a test result from a much bigger area.

Hardness & Tensile ConversionBelow is the reference conversion table for steel to convert the hardness to its tensile

strength.

There are parameters that could change the real result of the tensile strength testing, for example:

temper embrittlement, hydrogen embrittlement, percentage of carbon, amount of the impurity...

Surface Roughness ConversionIn Taiwan and China, usually we use metric "Ra" system for the surface roughness

measurement.

In USA, you can simply divide the inch roughness number by 40 to get the metric Ra number.

For example, if the inch drawing specifies surface roughness 32.

32 / 40 = Ra 0.8

Surface roughness can be specified in different way of measure. Below is a conversion

table of them.

Metal Standard ConversionMaterial Standard Conversion ASTM / DIN / JIS / BS / GB China / ISO / NF:

Below is a conversion table of the most frequently used materials in different national standards, as to the composition of the

materials, please refer to “Metal Material Composition”.

- Materials in different national standards might be slightly different in some detail compositions. It would be better to specify

which standard it is conforming to in the quotation and the purchase order.

- Due to the size limit of this web page, some of the materials could not be listed here. For example, some sheet metal

stamping materials CRS plates, Galvanized plates..If you would need more information, please contact SINAMA.

- Same material but in different shape or form might have different material numbers or names.

- The national standard of USA is ANSI, however ASTM is more frequently used

- There are a lot more materials available, but due to the size limit of this web page, we could

only make a list of the most frequently used ones.

- Also due to the size limit of this web page, the mechanical properties and some detail

requirements of the composition could not be included in this list.

- Materials could have different names when the form/utility is changed. For example, SS304

could be specified as CF-8 when used for casting processes.

- Any further information, please contact SINAMA, we will have our metallurgist to answer

your questions.
