How to choose the right type and grade for stainless steel products




Stainless steel is a manufacturing material that has great hardness and corrosion resistance. stainless steel flange can meet a vast range of design standards, as well as long service life, and does not need much maintenance. Consequently, to select the correct type and grade of suitable stainless steel products, four qualities need to be carefully weighed.

1. Resistance

This is the basic reason why you should specify stainless steel duplex flanges. It is important to know about the environment where the article will be and the level of heat or corrosion resistance necessary for the application.

2. Mechanical properties

The basis for the selection of a Stainless steel square bar is the combination of hardness and corrosion resistance. This quality involves a particular resistance to high or low temperatures.

3. Manufacturing operations

This point focuses on how the 304 stainless steel flanges will be created: manufacturing, grinding, welding, chamfering, forging, stamping, profiling, among others.

The quality of certain stainless steel bars depends on the specific processes to which the materials are subjected to obtain perfect hardness, safety, and roundness.

Among the most sought-after mechanical operations, today is the grinding without centers, which has been shown to produce an exact roundness.

4. Total cost

Additionally, production and material costs must be taken into account, as well as the increase in savings due to the durability of the grade 12.9 bolts and the low need for maintenance.

Application Requirements

The selection of a specific type of stainless steel inconel 625 bolts depends on the needs of the application.

For example, if it is necessary to create a Stainless Steel Round Bar, then austenitic steel is likely to be used. On the other hand, stainless steel bars for medical applications are available in martensitic steel.

The environment of a Stainless Steel Hex Bar, including the mechanical processes with which it is formed and its characteristics, such as resistance to corrosion and heat, will help to know what types of materials should be used.

Apart from those important qualities that must be considered, other factors must be taken into account.

  • The force needed: Austenitic, martensitic, duplex, and PH (precipitation hardened) steels may possess high strength. The force may change according to the series of processes to which they are subjected. For example, profiling and welding processes often influence a 304 stainless steel round bar, which is why it is necessary to know which material and grade of steel are most suitable.
  • Operating temperature: Often, the corrosion rate is accelerated by high temperatures. This means that a higher grade should be used. In general, low temperatures require strong austenitic steel.
  • Required product form: Not all grades of steel can be achieved in all sizes and shapes such as sheets, tubes, bars. Austenitic steel can offer a wide range of dimensions so that all products can be formed from it. In this way, most 316 stainless steel round bar is created from austenitic steel.
