一、产品简介
    HB-2锤击式布氏硬度计是以直径的刚球在施以瞬间的冲击载荷后，使刚球对压痕的测量，获取相应的数据，再通过压痕饿测量，获取相应的数据，再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、材料车间、材料仓库等测量布氏硬度理想的硬度计。
二、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）
    ★在精练淬火或淬火加回火状态下钢的布氏硬度值与抗拉强度值（限与非奥氏体钢）
    ★铸铁的布氏硬度值
    ★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）大倒角形的一端插入钢珠及衡头之间嵌装在体中的弹簧使衡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，从而获得较的数值。

One, product introduction
HB-2 hammering type Brinell hardness tester is a diameter just ball with instantaneous impact load, the ball indentation measurement, obtain the corresponding data, through measurement of indentation hungry, obtain the corresponding data, and then through the look-up table to obtain specimen hardness value. The hardness tester has the advantages of simple structure, convenient carrying, convenient use, is the industrial and mining enterprises, production workshop, workshop, warehouse and other materials materials measurement of Brinell hardness desired hardness meter.
Two, the use of methods
★in the natural state or a state of the steel annealed Brinell hardness and tensile strength values ( limited to non-austenitic steel )
★in refining quenching or quenching plus tempering state steel Brinell hardness and tensile strength values ( limit and non austenitic steel )
Brinell hardness of cast iron
Brass castings of the Brinell hardness value
★forging brass Brinell hardness value
★copper Brinell hardness value
Of the Brinell hardness value of tin bronze alloy
Aluminum alloy casting parts of the Brinell hardness value
Before trial should do the following preparation, test before the standard test block ( standard hardness test block ) large chamfering shape is inserted into the ball head and balance between embedded in the body of the balance spring head standard test block is tightly pressed on the steel ball.
On the surface of the material under test should be above the rust layer polishing to obtain a flat and smooth surface, so that the test specimen to obtain clear ball indentation, so as to obtain more accurate numerical.
