In the detection of threaded fasteners, it is not possible to simply check the relevant manual according to the hardness value, and convert the strength value. This has a hardenability factor in the middle. Because the national standard GB3098.1 and the national standard GB3098.3 stipulate that the hardness of the arbitration is measured at the 1/2 radius of the cross section of the part. Tensile specimens are also taken from the 1/2 radius. This does not exclude the presence of low-hardness, low-strength parts in the central part of the part.
In general, the hardenability of the material is good, and the hardness of the screw section can be evenly distributed across the cross section. As long as the hardness is acceptable, the strength and guaranteed stress can meet the requirements. However, when the hardenability of the material is poor, although the hardness is acceptable although inspected according to the specified location, the strength and the guaranteed stress often fail to meet the requirements. Especially when the surface hardness tends to lower limit.
