Stainless steel usually refers to steel that is resistant to air, water, acid, alkali salt or other corrosive substances.According to the composition of the alloy, the emphasis is on rust and acid resistance.Some of the steel is not rustproof, but not necessarily acid, and acid-resistant steel is usually stainless.The main products used in the production fasteners are austenitic stainless steel, which is often referred to as austenitic stainless steel in People's Daily life.We use stainless steel fasteners, the raw material mainly USES the austenite 302, 304, 316 and "low nickel" 201.


Stainless steel screws do not necessarily corrode rust, only that stainless steel screws are more likely to rust than iron screws.But stainless steel screws will rust in certain situations.So stainless steel screw in what condition easy to cause rusting!What are the causes of rust?

Stainless steel screw has good characteristics, strong corrosion resistance, high temperature resistance, and strong rust resistance.But it will rust in harsh conditions.For example, stainless steel screws in very wet conditions, daily sun exposure, wind and rain.It will be a little rusty for a long time.Contact with some acid-base chemicals to produce chemical reactions.Cause corrosion to rust.There is already a bad stainless steel screws, such as material for stainless steel SUS201 screws to use the product in the water of the sea, because often time of soaking, originally SUS201 stainless steel screw itself is not very suitable for the water of the sea salt resistant used above.Cause corrosion to rust.The use of seawater products is generally recommended to use stainless steel SUS316 screws, because 316 stainless steel screws can carry corrosion and other performance is better.

It can be concluded from the above that stainless steel screws will corrode and rust in certain situations.Therefore, this requires reasonable use of stainless steel screws.Use stainless steel screws with different materials under different conditions.Moreover, in different occasions, when using stainless steel screws, special attention should be paid to the details.As far as possible stainless steel screw corrosion rust control.


Stainless steel screw is widely used in machinery, petrochemical, telecommunications, chemical industry, construction industry, electric power, textile, sports equipment, paper making, sewage treatment, ship, automobile and other industries, with domestic economic living standards greatly improved the application range of the stainless steel screw will be more extensive.
