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 kinds of electroplating of iron combination screws: ordinary and environmentally friendly. For example: color zinc, generally called red color. White zinc, black zinc, white nickel. Blue zinc. There are environmentally friendly color zinc, environmentally friendly white zinc, and environmentally friendly blue zinc. Environmentally friendly white nickel. There are more advanced ones. Nickel on copper, nickel in brine. Tools/Materials Screw wires, iron screw wires include 1010, 1018, 10B21, etc. Stainless steel screw wires include SUS201, SUS304, etc. Steps/Methods The requirements for the material of the combined screw depend on which material is required, whether it is iron or stainless steel. What is the national standard number of the combination screw? There are GB9074.8 and GB9074.4. There are GB9074.13 and so on. The mechanical performance and strength requirements of the combined screw need not be hardened. The level requirements are divided into 4.8 and 8.8 l...
