&Nbsp; Stainless iron passivation solution
Overview of stainless iron passivation: stainless iron passivation solution is also called martensitic stainless steel passivation solution
Many friends may not understand it
There are also material differences in stainless steel
For example, 200 and 300 series stainless steel materials are called austenitic stainless steel, while 400 series materials are called martensitic stainless steel, commonly known as stainless iron materials
Due to the high carbon content of stainless iron, the rust prevention performance of stainless steel is relatively lower than that of austenitic series stainless steel
Therefore, a passivation treatment must be done to improve the rust prevention performance of the workpiece
So how should stainless iron be passivated? The following is about the process flow of stainless iron passivation and the advantages after passivation

Brief introduction of stainless iron passivation solution: stainless iron passivation solution is only developed for sus400 series Ferritic and martensitic stainless steels to improve corrosion resistance
It belongs to a new type of high-quality product for general primary color passivation of martensitic materials

This product is made of environmental friendly organic acid as the main oxidant, high-efficiency anode adsorption intermediate auxiliary, high-quality corrosion inhibitor and a small amount of high molecular passivation accelerator
It is non-toxic and tasteless without acid corrosion components
Through passivation of this product, it can effectively ensure that the original color of the workpiece will not be damaged during passivation, the size of the workpiece will not be changed, and the salt spray resistance of stainless steel workpiece will be greatly improved
For example, all types of stainless iron materials such as 400 series nickel free stainless steel 410, 420, 430, 1Cr13, 2Cr13 and 3r13 are used to improve the corrosion resistance of their workpieces
The treated workpieces do not change the original color, and the salt spray resistance can be increased by 6 to 100 times, up to 780h of neutral salt spray test
Due to the formation of a dense and indestructible passivation film on the workpiece surface during passivation treatment, it is widely used in the fields of screws, fasteners, medical devices, blades, Magda shafts and so on, and has a very broad prospect

Advantages of stainless iron passivation solution:
1
  Non toxic, low corrosion, no special equipment, general plastic containers

2
  Increase the precision and added value of products

3
  Greatly improve the salt spray rust prevention performance of stainless iron materials

4
  The passivation solution does not contain harmful substances, complies with ROHS, reach and other environmental specifications, and has passed SGS and FDA certification

5
  Through the blue dot method uniformly stipulated by the state, there is no blue dot in 35 seconds

Precautions for stainless iron passivation solution:
1
  Containers for passivation can generally adopt plastic boxes, plastic tanks and stainless steel tanks

2
  The passivation temperature is 70 ℃ for 30 minutes, and the stable temperature is 60 ℃ for 15 minutes

3
  Suitable for 400 series martensitic stainless steel

4
  Operators shall wear labor protection equipment during operation to avoid contact between liquid agent and skin

5
  Wastewater treatment, neutralization with alkaline lime water or sodium hydroxide, etc
, and discharge when the pH value reaches 7, which has no impact on the environment

Storage and packaging:
The temperature of the product shall not exceed 75 ℃ during storage, loading and unloading
If it is stored for a long time, the temperature shall not exceed 45 ℃
The passivation liquid is not easy to burn, explosive, corrosive and environmentally friendly
