How to choose stainless steel nozzles (understand the characteristics of common materials used in stainless steel nozzles)
Stainless steel metal nozzles are typically made from 303SS, 304SS, 316SS, 316L, 316F, 416SS, and 440C.
303SS has good abrasion resistance.
304 stainless steel nozzles have strong corrosion resistance, good resistance to alkali solutions and most organic and inorganic acids.
316F stainless steel nozzle is easy to cut with high sulfur content. Good corrosion resistance, easy machining and good finish making it suitable for parts such as shafts.
316SS has excellent strength against atmospheric corrosion and high temperature.
316L has a wide range of applications in the chemical industry due to its excellent corrosion resistance with 2 to 3% Mo element added. On the basis of 316L, many steel grades are derived, such as 316Ti derived from the addition of a small amount of Ti, 316N derived from the addition of a small amount of N, and 317L derived from the increase of Ni and Mo content.
440C is mainly used to manufacture bearing parts in corrosive and non-lubricated strong oxidizing working environment.
440C can be used as a bearing steel for corrosion and high temperature resistance, and it can also be used to make high quality knives, such as medical scalpels, scissors, nozzles, bearings and so on.
The diversification of stainless steel nozzle materials makes them more widely used, which is why most customers choose stainless steel nozzles after thinking about it.
When choosing stainless steel nozzles, the following factors need to be considered:
1. Orifice of the nozzle: directly affect the spray effect and spray volume. Generally the smaller the caliber of the nozzle, the more delicate spray effect, but the impact of resistance will lead to insufficient spray volume. When choosing the caliber of the nozzle, you need to take into account the specific needs of the use.
2. The structure of the nozzle: different structures of the nozzle is suitable for different occasions. For example, built-in nozzle for viscous liquid, external nozzle for a larger range of occasions. When choosing, you need to choose with the specific needs of the use.
3. Selection of materials: stainless steel is a common good corrosion and abrasion resistance of the material, applicable to a variety of industrial fields. But in some special occasions, such as high temperature, high pressure and other environments, you may need to choose a more heat-resistant, corrosion-resistant materials.
4. Flow of the nozzle: influence the effect and scope of the spray. The larger the flow, the wider the spray range, but at the same time the spray effect will also be affected. Therefore, when choosing the nozzle flow, you need to consider the actual demand.
In addition, it is also necessary to pay attention to the spray angle, spray pattern and the actual need for comprehensive consideration in order to achieve the best spray effect.
