The reason with stainless steel rusty sumbersible pump

2023-11-01 10:36:35

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The sumbersible pump that is a major produces manufacturer. When type selecting of client sumbersible pump, manufacturer of my company water pump can provide the before-sales service such as price of sumbersible pump model, sumbersible pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is about stainless steel sumbersible pump rusts the knowledge of the reason:

What is stainless steel?
Have the capacity that counteractive air oxidizes, in also having the medium that containing acerbity, alkaline, salt at the same time anticorrosive a kind of rolled steel of ability!
Why does stainless steel sumbersible pump fight rust?
Stainless steelSumbersible pumpThe surface added the element such as press or rub against and nickel, form paper-thin and the film of rich chromic oxidation that stabilizes compactly stably (defend film) , prevent oxygen atomic to continue infiltration, continue to oxidize, and obtain fight rustily ability. When compact oxidation covering layer is destroyed, stainless steel pump can rust.
The meeting below what condition destroys diaphragm?
1. bleaching powder 2. Mechanical wear 3. Water
Stainless steel sumbersible pump is phyletic:
Stainless steel sumbersible pump divides a lot of sort, attribute is different, use environment is different.
For example: Sumbersible pump of 304 stainless steel, in the air of dry cleanness, have fight rustily ability admirably absolutely, but move it littoral area, in the sea fog that contains many salt portion, can rust very quickly; And 316 steel tube are behaved good.
Can divide the department that it is Cr by composition (SUS400) , Cr – Ni is (SUS300) , Cr – Mn – Ni (SUS200) reaching separate out sclerosis is (SUS600) .
200 series – chromic – nickel – manganese austenite stainless steel.
300 series – chromic – nickel austenite stainless steel.
It is good that 301- extends a gender, use at shaping product. Also can make its rapid and sclerotic through machining. Weldability is good. Anti-wear properties and fatigue intensity excel 304 stainless steel.
302- corrosion resistance is the same as 304, because contain carbon,want relatively tall strength is consequently better.
303- is passed add a few sulfur, phosphor makes its relatively treatment of 304 easier cutting.
304- namely 18/8 stainless steel. GB brand is 0Cr18Ni9.
309- than 304 have better be able to bear or endure lukewarm sex.
316- afterwards the after of 304, the 2nd gets the steel that uses more extensively is planted, basically use at food industry and surgical operation equipment, add molybdenum element to make its obtain a kind to fight cankerous special structure. As a result of than 304 its are had better fight chloride to corrode ability to also be made consequently marine steel will use. SS316 is used at nuclear fuel to reclaim normally device. 18/10 class stainless steel also accords with this application level normally.
321- besides because added titanium element,dropped material welding line other property is similar besides rustily risk 304.
400 series – ferrite and martensite stainless steel.
408- hear resistance is good, weak corrosion resistance, the Cr of 11% , the Ni of 8% .
The model with cheaper 409- (flower beauty) , use as normally car vent-pipe, belong to ferrite stainless steel (chromium steel) .
410- martensite (high strenth chromium steel) , wearability is good, corrosion resistance is poorer.
416- added sulfur to improve the treatment performance of material.
Class of 420- cutting tool – martensite steel, tall chromium steel of similar cloth family name stainless steel of this kind of prior. Also use at surgical operation cutting tool, what can do is very shining.
430- ferrite stainless steel, adornment is used, use at car act the role ofing to taste for example. Shape goodly quality, but be able to bear or endure Wen Xinghe corrosion resistance wants difference.
Steel of cutting tool of 440- high strenth, contain carbon tallish, after can obtain the heat treatment with proper course to succumb higher intensity, hardness can achieve 58HRC, belong to harder stainless steel. Commonner applied example is razor piece. Commonly used model has 3 kinds: 440A, 440B, 440C, still have 440F additionally (easy treatment) .
500 series – heat-resisting chromic alloy steel.
600 series – stainless steel of martensite precipitation sclerosis.
The model of precipitation sclerosis stainless steel with more commonly used 630- , also call 17-4 normally; 17%Cr, 4%Ni.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is about stainless steel sumbersible pump rusts the introduction of the reason, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company still produces the pump below fluid, welcome you at any time seek advice.
