Metric Stainless Screws - Some Interesting Facts
Metric stainless steel screws have been an important engineering material for years - very useful most especially in aviation, construction, and other industries.
What's the big deal about this kind of material? Why is it popular in the industry? When do you need to choose metric stainless screws for your project? These are important questions we need to address. And some interesting facts below can help us find the answers.
An ordinary metal like carbon steel screw is prone to rusting. Exposure of this material to oxygen would lead to oxidation - a chemical reaction between the material and the atmosphere. And, it is important to note that the more corrosive your environment, the faster oxidation process would take place. Seaside for instance is more corrosive - metals corrode more quickly when near the sea.
Although industries used to be satisfied with carbon steel for centuries, the fast-paced environment and the tough competition pushed people in the industry to look for improved engineering materials. Indeed, there had been a metal revolution in the industry.
Thanks to the innovative people in the industry - metric stainless screws solve the problem of rusting. What's with the stainless metal screws that make them, well, stainless? Stainless steel materials contain at least 11% chromium. When this metal is mixed into the steel, it oxidizes too - but it oxidizes into a super-strong, corrosion-resistant film of chromium oxide. This outer layer of chromium oxide serves as a kind of protective covering that prevents rust from penetrating the steel.
Metric stainless screw has become an industry standard
Precisely because stainless metal material can give what the industry needs, it has become an industry standard for production, construction, aviation - among other component of the industry. It helps in building a more quality structures and products.
Other reasons for this recognition include:
These screws maintain their strength when exposed to extreme temperatures ( hot or cold)
They are easy to clean and nice to look at - because they are stainless!
Longer lifespan because of its anti-corrosive properties
Highly resistant to magnetic forces as well
Metric stainless screw - a clear winner
If you are building a structure, it is important that you underscore the location as a factor in choosing the type of materials to use. If it is meant to last, particularly around chemicals and salt water exposure, metric steel screw is a clear winner!
There are many types of materials for making stainless steel screws, and they can be divided into several categories according to the structure at room temperature: austenitic type: such as 304, 321, 316, 310, etc.; martensite or ferrite type: such as 430, 420, 410 Wait; Austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will result. In this way, 304 stainless steel will have weak magnetic properties. After 304 stainless steel is cold worked, the structure will also be transformed into martensite. The greater the degree of cold working deformation, the more martensite transformation and the greater the magnetic properties of the steel. Like a batch of steel belts, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. Because the bending deformation...
