Brinell and Rockwell Hardness Conversion Chart - These Conversion Tables presents data in the Rockwell A, B, C, D, E and F hardness range on the relationship among Brinell hardness, Vickers hardness, Rockwell and Shore Scleroscope hardness
Brinell Hardness Number - BHN - The Engineering ToolBox
The Brinell hardness test is commonly used to determine the hardness of materials like metals and alloys. The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter.
Brinell hardness test - Wikipedia
The Brinell hardness test (pronounced / b r ə ˈ n ɛ l /) measures the indentation hardness of materials. It determines hardness through the scale of penetration of an indenter, loaded on a material test-piece.

布氏硬度试验(Brinell scale)是压入硬度试验之一种,其测量值用HB或BHN表示, 布氏硬度值称为BHN(Brinell Hardness Number),常被简写为HB(Hardness Brinell)。 报告布氏硬度值的时候,必须注明试验条件。
Rockwell to Brinell Hardness Conversion Chart
For instance, converting from a Rockwell hardness test on the C scale (HRC) to a Brinell hardness test value requires using the formula: BHN = 5.970 x (HRC + 104.7). This formula gives an approximate value for the Brinell hardness value, and quality assessment professionals use it to create the conversion tables and charts for instant conversion.

布氏硬度试验是一种通过将硬球压入材料表面来确定材料硬度的方法。 该方法提供对变形抵抗力的度量,并广泛用于金属测试。 布氏硬度试验是由瑞典工程师约翰·奥古斯特·布氏在 20 世纪初开发的。 它是测量金属硬度的第一个标准化方法,并迅速成为工程领域的标准。 d d 是压痕直径,以毫米为单位。 布氏硬度试验对于比较不同材料的硬度而言至关重要。 它广泛用于冶金学,以确保材料满足其预期用途的必要规格。 布氏硬度值的重要性是什么? BHN 给出一个反映材料硬度的 …
布氏硬度HB与勃氏硬度BHN之间什么关系啊! - 百度知道
布氏硬度试验(Brinell scale)是压入硬度试验之一种,其测量值用HB或BHN表示, 报告布氏硬度值的时候,必须注明试验条件。 使用标准方法记录的试验条件如HBW 10/3000中,HBW指使用碳化钨压头(W是钨的化学符号,使用钢压头的则记为HBS),10指的是用毫米测量的压 ...

2024年4月29日 · Brinell Hardness Test (BHN) The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or tungsten ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation.
