Brinell Test

Brinell Test. It is pressed into the specimen to make the indent in the specimen by applying load. The Brinell method applies a predetermined test load F to a carbide ball of fixed diameter D which is held for a predetermined time period and then removed.

Brinell testing often use a very high test load 3000 kgf and a 10mm diameter indenter so that the resulting indentation averages out most surface and sub-surface inconsistencies. 53 rows The Brinell hardness test is commonly used to determine the hardness of materials like. In the USA Brinell testing is typically done on iron and steel castings using a 3000Kg test force and a 10mm diameter carbide ball.

The Brinell method applies a predetermined test load F to a carbide ball of fixed diameter D which is held for a predetermined time period and then removed.

Brinell Hardness Testing is a nondestructive testing method that determines the hardness of a metal by measuring the size of an indentation left by an indenter. Brinell Hardness number Load Curved surface area of the indentation. Metals are commonly tested in this way and the Brinell test can also be used on woods and some other materials. The Brinell hardness test consists of applying a constant load usually in the range 5003000 N for a specified period of time 1030 s using a 5 or 10 mm diameter hardened steel or tungsten carbide ball on the flat surface of a work piece.
