Physical Properties
1. There are chloride ions in the operating environment.
Chloride ions are found in salt, sweat, sea water, wind, soil, etc. Stainless steel corrodes faster in the presence of chloride ions than ordinary mild steel.
So the use of stainless steel environment has requirements, and the need to often wipe, remove dust, keep clean and dry. (This gives him an “inappropriate use.”)
There is an example in the United States: an enterprise used an oak container to hold a solution containing chloride ions. The container has been used for more than a hundred years and was planned to be replaced in the 1990s. Because the oak material was not modern enough, the container was corroded and leaked 16 days after the replacement with stainless steel.
2. No solution treatment.
Alloy elements did not dissolve into the matrix, resulting in low alloy content in the matrix structure and poor corrosion resistance.
3. Such materials without titanium and niobium have a natural tendency to intergranular corrosion.
The addition of titanium and niobium, combined with stable treatment, can reduce intergranular corrosion.
In the air or chemical corrosion medium can resist corrosion of a high alloy steel, stainless steel is a beautiful surface and good corrosion resistance, do not have to be plated and other surface treatment, and play the inherent surface properties of stainless steel, used in many aspects of a kind of steel, usually called stainless steel. On behalf of the performance of 13 chromium steel, 18-8 chromium nickel steel and other high alloy steel.
From the metallographic point of view, because stainless steel contains chromium and the surface of the formation of a very thin chromium film, the film separated from the oxygen in the steel invasion of corrosion resistance.
To maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12% chromium.
304stainless steel Shim Plates is a universal stainless steel, which is widely used in the manufacture of equipment and parts requiring good comprehensive properties (corrosion resistance and formability).
304 stainless steel is a brand of stainless steel produced in accordance with ASTM standards in the United States. 304 is equivalent to China’s 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 contains 19% chromium and 9% nickel.
304 is the most widely used stainless/heat resistant steel. Used in food production equipment/xiton chemical equipment/nuclear energy, etc.
304 corresponds to the Chinese brand 0Cr18Ni9,1Cr18Ni9Ti, carbon content ≤0:08%
304Lstainless steel Shim Plates is a variant of 304stainless steel Shim Plates stainless steel with lower carbon content and is used for welding applications. The lower carbon content minimizes carbides precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.
