Stainless steel screws, as the name suggests, the screws are made of stainless steel wire. Stainless steel is usually denoted by the letter SUS. Stainless steel screws generally have 201 stainless steel, 304 stainless steel, 316 stainless steel, 404 stainless steel and so on. Generally we often say that the stainless steel screw is SUS304, refers to the stainless steel screw material is 304. In this on the stainless steel screw material introduction to this. Next, Anzhikou hardware tell you about the stainless steel screw cleaning process description:

Stainless steel screw cleaning process: oil removal → full water wash → oxidation peel → full water wash → polishing → full water wash →70 ~ 90℃ hot water immersion for 10 seconds → mechanical dry

Stainless steel screw cleaning process instructions: 

1, Stainless steel screw cleaning and oil removal 

Anzhikou hardware suggests the use of weak acid, high performance oil removal agent HS-HBCY02, cleaning agent for weak acid liquid, oil with good penetration, dispersion, wetting, saponification, emulsification ability, with extremely excellent cleaning performance. 

(1) stainless steel screw cleaning temperature: room temperature 

(2) stainless steel screw cleaning method: Add the HS-HBCY02 stock solution into the mechanical vibration tank, the stainless steel screw mechanical vibration cleaning time after the appropriate water. 

(3) stainless steel screw cleaning time: 3 ~ 8 minutes 

(4) stainless steel screw cleaning agent usage: 100kg; Stainless steel screw added HS-HBCY02:0.25 ~ 0.5kg.

2. Remove the oxide skin 

Anzhikou hardware is recommended to use stainless steel screw is special detergent HS - HBQX02, cleaning agents for moderate acid liquid, and the complex surface scale, special structure, such as stainless steel screws, carbide have excellent removal performance, after cleaning of stainless steel screws, and can accelerate the passivation of stainless steel surface, make after cleaning stainless steel screws with good resistance to salt fog performance. 

(1) stainless steel screw to remove the skin of the use of temperature: room temperature 

(2) The method used when the stainless steel screw is oxidized: the HS-HBQX02 stock solution is added to the mechanical vibration tank, the stainless steel screw mechanical vibration cleaning after the appropriate time of water. 

(3) stainless steel screw oxidation cleaning time: 2 ~ 30 minutes. 

(4) stainless steel screw to oxidize the amount of agent: 100kg; Stainless steel screw add HS-HBQX02:1 ~ 5kg.

3, Polishing 

It is recommended that HS-HBPG03, a special grinding and polishing liquid for stainless steel screws, be used. The polishing liquid is a weak acidic viscous liquid, which has excellent polishing performance for stainless steel screws. The polished stainless steel screws are shiny and have a very beautiful appearance. 

(1) Stainless steel screw polishing temperature: room temperature 

(2) The method used when polishing stainless steel screws: add the HS-HBPG03 stock solution into the vibration tank, and use mechanical vibration to polish the stainless steel small parts for a certain period of time after clean water. 

(3) stainless steel screw polishing time: 10 ~ 30 minutes. 

(4) stainless steel screw polishing agent usage: 100kg; Add HS-HBPG03 polishing solution 0.5 ~ 1.0kg for stainless steel screws.
