奥龙HB-2 锤击式布氏硬度计

HB-2 锤击式布氏硬度计

       HB-2型锤击式布氏硬度计是以一定直径的钢球在施以瞬间的冲击载荷后，使钢球陷于被测试标准硬度试块或被测试件中，从而获得压痕，通过对压痕的测量，获取相应的数据,在通过查表即可获得试件的硬度值。本硬度计构造简单，便于携带，使用方便，是工矿企业、生产车间、材料仓库等测量布氏硬度理想的硬度计。

主要测试对象及使用方法

在天然状态或退火状态下钢的布氏硬度值与抗拉强度值

（限于非奥氏体钢）

在精炼淬火或淬火加回火状态下钢的布氏硬度值与抗拉强度值

（限于非奥氏体钢）

铸造的布氏硬度值

黄铜铸件的布氏硬度值

辗压黄铜的布氏硬度值

紫铜的布氏硬度值

锡青铜合金的布氏硬度值

铝合金铸件的布氏硬度值

    在试验前应做好如下准备工作，试验前首先将标准 试块（标准硬度试块）大倒角型的一端插入钢珠压头之间嵌装在壳体中的弹簧使压头将标准 试块紧压在钢珠上。

    在被测试材料的表面上应将其上面锈蚀层磨光使之得到一平坦且光滑的表面，以便在试验时试件上得到清晰的钢珠压痕，从而获得较精确的数值。

Model HB-2 hammering Brinell hardness tester

HB-2 hammering Brinell hardness tester is the diameter of the ball must be subjected to an instant after the impact load, so the ball is caught testing standard hardness test block or test pieces, thereby obtaining indentation, By measurement of the indentation, obtain the appropriate data, you can get the hardness of the specimen in the look-up table. The hardness of simple structure, easy to carry, easy to use and is ideal for industrial and mining enterprises, workshops, warehouses and other materials Brinell hardness measurement.

The main test object and method of use 

Brinell hardness and tensile strength values in the natural state or annealed steel 

(Limited to non-austenitic steels) 

Brinell hardness and tensile strength values in the refining quenched or quenched and tempered condition steel 

(Limited to non-austenitic steels) 

Brinell hardness casting 

Brinell hardness brass castings 

Brinell hardness rolling brass 

Brinell hardness of copper 

Brinell hardness bronze alloy 

Brinell hardness of aluminum alloy castings 

Before the test should do the following preparations before the first test standards Test block (standard hardness test block) is inserted into one end of the large chamfered ball head fitted in the housing between the spring standard ram Test block is pressed against the ball. 

On the surface of the material being tested should be at the level of corrosion to give a polished so that the surface is flat and smooth, so that during the test to get a clear impression on the ball test piece, to obtain more accurate values.
