Stainless steel is a kind of high alloy steel that can resist corrosion in the air or chemical corrosion medium, with beautiful surface and good corrosion resistance, without surface treatment such as plating color.
Tip 1: there are many kinds of stainless steel, which can be divided into the following categories according to the structure at room temperature:
1, austenitic stainless steel: such as 304, 321, 316, 310, etc.;
2, martensite or ferrite stainless steel: such as 430, 420, 410;
The austenitic body is nonmagnetic or weakly magnetic, and the martensitic and ferritic bodies are magnetic.
Whether or not stainless steel products are magnetic depends on the internal components of the material itself.
The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
Chromium is the basic element to make stainless steel obtain corrosion resistance. When the content of chromium in the steel reaches about 1.2%, the oxygen in the corrosion medium ACTS with chromium to form a very thin oxide film (self-passivation film) on the surface of the steel, which can prevent further corrosion of the steel matrix.
In addition to chromium, common alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various USES of stainless steel structure and performance requirements.
Tip 3: stainless steel can be recycled.
The main sources of waste stainless steel are stainless steel waste generated by industrial manufacturing and stainless steel process, damaged and scrapped stainless steel equipment after long-term use, and stainless steel appliances used in daily life.
They can only be recycled into other stainless steel products or products after scrap.
Tip 4: metal expansion and contraction.
You can make stainless steel soap to clean your hands of fish, garlic, Onions and other odors.
