ASTM E140, Change 12B, – Basic Firmness Conversion Tables to possess Gold and silver Relationships One of Brinell Firmness, Vickers Hardness, Rockwell Hardness, Shallow Stiffness, Knoop Stiffness, Scleroscope Hardness, and Leeb Stiffness
Conversion process Table 1 presents study about Rockwell C firmness range towards dating certainly one of Brinell firmness, Vickers stiffness, Rockwell hardness, Rockwell shallow hardness, Knoop stiffness, and you can Scleroscope stiffness from low-austenitic steels plus carbon, alloy, and you may product steels regarding the given that-forged, annealed, stabilized, and you will quenched and you may tempered criteria so long as he is homogeneous.
These types of firmness transformation relationships were created to put on such with the following: nickel-aluminum-silicon specimens done to commercial mill conditions to have hardness analysis, since the entire range of these types of metals off their annealed in order to their greatly cool-has worked otherwise many years-hardened requirements, and their intermediate standards
Conversion Desk 2 gift ideas analysis about Rockwell B hardness range on the dating certainly one of Brinell stiffness, Vickers firmness, Rockwell stiffness, Rockwell low hardness, Knoop stiffness, and you will Scleroscope firmness of low-austenitic steels and carbon dioxide, metal, and you can tool steels on the due to the fact-forged, annealed, stabilized, and you may quenched and you can tempered criteria provided he is homogeneous.
Sales Desk step 3 gift suggestions investigation into relationship certainly one of https://datingranking.net/local-hookup/brantford/ Brinell stiffness, Vickers stiffness, Rockwell hardness, Rockwell low firmness, and you may Knoop hardness out of nickel and you can highest-nickel metals (nickel stuff over fifty %).
Sales Dining table cuatro gifts data with the matchmaking among Brinell firmness, Vickers hardness, Rockwell stiffness, and you may Rockwell low stiffness out-of cartridge metal.
Conversion Table seven gift ideas studies to your relationships one of Brinell firmness, Vickers stiffness, Rockwell stiffness, Rockwell low stiffness, and you will Knoop stiffness out of copper.
Conversion Dining table 8 gift ideas study toward dating certainly Brinell firmness, Rockwell stiffness, and Vickers stiffness out-of alloyed white iron.
Sales Dining table 9 merchandise studies with the relationships among Brinell stiffness, Vickers stiffness, Rockwell hardness, and Rockwell superficial stiffness from wrought aluminum situations.
Sales Desk ten gift suggestions studies regarding the Rockwell C stiffness assortment to your relationship one of Leeb (Variety of D) firmness, Brinell firmness, Vickers firmness, and you will Rockwell firmness of low-austenitic steels and additionally carbon dioxide, metal, and you will tool steels regarding the as the-forged, annealed, normalized, and quenched and tempered requirements so long as he is homogeneous.
Sales Dining table 5 gifts data into matchmaking anywhere between Brinell firmness and you can Rockwell B firmness from austenitic stainless steel dish regarding annealed standing
A number of the conversion viewpoints presented here have been taken from computer-made curves out of actual decide to try research. Most Rockwell hardness wide variety was made available to the nearby 0.step one or 0.5 firmness matter to permit perfect reproduction of those shape.
Annex A1 – Annex A10 incorporate equations to alter from 1 hardness level in order to several other. This new equations considering in Annex A1 – Annex A9 was in fact build about data into the Dining tables step 1 in order to 9, correspondingly. The newest equations provided in Annex A10 was in fact arranged during the time the new Leeb hardness take to try devised (come across Appendix X2). The data for the Dining table ten try determined in the Annex A10 equations.
Conversion away from hardness beliefs is going to be used only if it is impossible to try the material under the requirements given, and if transformation is generated it should be done with discretion and you can not as much as controlled standards. Each kind out of stiffness sample is actually subject to particular errors, however, if precautions was carefully noticed, the fresh precision regarding firmness readings generated for the products of one’s indentation type could well be discover similar. Variations in susceptibility inside listing of a given stiffness size (particularly, Rockwell B) is greater than between a couple of some other balances or brand of tool. The conversion process philosophy, whether or not regarding the dining tables or determined on the equations, are merely calculate and can even feel wrong getting specific software.
