Dimensional tolerances for nitrided alloy steel bars

The allowable tolerance for Nitrided Alloy Steel rod size can be rather complex. This is due to the use of different types of Nitrided Alloy Steel, which all have their own individual tolerances. The process of nitriding is a very important process that adds properties to the steel that improve its performance and increases its hardness, strength and ductility.

When considering the size tolerance for Nitrided Alloy Steel, it is important to note that there are two different types of surfaces, which are called a “processed surface” and a “raw surface”. The processed surface is the surface that has been subjected to the nitriding process and this surface can have a tolerance of up to 0.50mm and can have a roughness finish up to Ra1.6 and up to Ra12 microfinish for the ground finished part. This tolerance is based on the size of the rod and the finish, meaning if the size tolerance of the rod is greater than 0.50mm then the finish can be up to Ra1.6.

The raw surface is the surface that is not processed by the nitriding process. For raw surfaces, the tolerance will be much lower and can have a tolerance of up to 0.15mm and up to Ra2.5 microfinish.

The strength of the Nitrided Alloy Steel rod is also an important factor to consider when determining size tolerance. An average strength of Nitrided Alloy Steel rod is 65-67 HRC, which is much stronger than traditionally carbon steel. As a result, it is important to consider that the size of the rod should be taken into consideration with any tolerances applied.

In addition to size tolerance, there are also other factors to consider when using Nitrided Alloy Steel. For example, nitriding creates an additional layer of wear protection, which when combined with a proper choice of lubricant and sealants, can increase performance and wear protection. In many cases, it is also necessary to properly preheat parts before nitriding them. This helps to ensure that the desired properties of the Nitrided Alloy Steel rod are achieved.

As such, size tolerance of Nitrided Alloy Steel must be carefully considered along with other factors when determining the optimal application of the material. The size tolerance of Nitrided Alloy Steel can be quite complex, but ultimately, it is important to be aware of all associated factors before deciding which type and size of material is best for a given application.

Nitrogen-alloyed steel bar is a kind of steel bar made of nitrogen-alloyed steel. It is widely used in production and life because of its excellent performance.

Nitrogen-alloyed steel bars are often used in combination with other materials or components to maintain or increase the strength or hardness of the material or component. They are often used in ships and bridges, as well as in construction and industrial processes.

The most important factor when manufacturing nitrogen-alloyed steel bars is ensuring that the standard size and tolerance requirements are met. In general, the tolerance range of the round bar steel is 6 and 12mm, and the tolerance range for the flat bar steel is 6 and 10mm. In addition, the size of the nitrogen-alloyed steel bar must remain within the allowable deviation range specified in the product standard.

The allowable deviation of the nitrogenized steel bar size is ≤0.15mm for the outer diameter, ≤0.05mm for the wall thickness and ≤0.02mm for the length. In addition, the surface roughness should not exceed Ra3.2 and the maximum deviation of the round bar should not exceed 0.3mm.

It is very important to maintain the accuracy of the size of the steel bar, because if the size is not accurate, it will cause a lot of inconvenience in use and will also reduce the usage effect. Therefore, it is necessary to strictly control the manufacturing process and ensure that the size is within the allowable deviation.
