What is meant by strength of 316 stainless steel angle the tensile

 

A said 316 stainless steel angle tensile strength, as if there is to understand the feeling, less in theory seems to be stronger than the strength of the expression, with the role of external force Lashin the same diameter of the bar, more rupture when the force can be. In the scientific often said tensile strength, is the requirement of the test piece, in the requirement of the test instrument, in accordance with the prescribed experimental way measured the standard value.

 

316 stainless steel angle compressive strength specimen has 1 to 14 16 fixed immobile look and specifications. The application of such specimens lies in the type of raw material being tested, such as: bar, plate, cable, etc. This specification is required on JIS. In addition to tensile strength, it can also test yield strength, required residual extension ground stress, post-break elongation, cross-sectional shrinkage, etc., and the way of its testing is also required on JIS.

In the JIS specification of 316 stainless steel angle, according to its specification type (the main use) is different, the standard value of this new item is required. The cable only specific tensile strength, and alloy structural steel not only required yield strength, but also required residual extension ground stress, elongation after break, cross-sectional shrinkage, etc. 316 stainless steel angle compressive strength test, is clamped to both sides of the specification specimen, gradually pull Shen to rupture cut-off. There is no way to ensure the consistency of the test piece and goods, but only in large enterprises processing and manufacturing, and carried out sufficient quality control, there should not be a big difference. Especially if the heat treatment process is done, there is no concern that the product is not consistent with the specimen.

 

Tensile strength: tensile force in addition to the original cross-sectional area of the location of the parallel surface of the specimen business for kgf/square wire, generally omitted f and square wire only with kg. 41 in SS41 indicates that his tensile strength of 41kg. (Tensile strength business and writing and in our country is not the same, such as the Japanese tensile strength written 41kg; in our country is the choice of international unit system, which matches the Written 410MPa or 410N / square wire.

 

Elongation after break: the amount of extension of the test piece after rupture and the percentage of the original length (%).

 

Yield strength: In the whole process of the tensile test, there is a sudden reduction in ground stress, and in the ground stress will not change the large condition of the specimen is still elongated ground stress point. This ground stress point is called yield strength, with kgf / square wire, generally omitted f and square wire only with kg indicates. For metal composites, do not address its increase in force than it.

 

Requirement of residual extension compressive strength: The yield limit of other objects is not significant except for alloy steel. It can be indicated by the required residual extension ground stress. That is: in the tensile test, although the Rashen force is cleared, the specimen can no longer be restored to its original form and maintain 0.2% of the extension. This is indicated by kgf/square wire. Because of plastic deformation up to 0.2%, this raw material can no longer be used, so this is the specified value.

 

Cross-sectional shrinkage: that is, the larger reduction in cross-sectional area of the test piece after tearing (the difference between the beginning of the cross-section and less cross-section) and the percentage of the initial cross-sectional area of the test piece.
