Customized 316L Stainless Steel Plate Steel Buildings Kits for Parts Containers and Equipment

The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plate refers to steel plate resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to steel plate resistant to corrosion by chemical corrosive media such as acid, alkali and salt.

Performance:
Corrosion resistance
The stainless steel plate has the ability to resist general corrosion similar to the unstable nickel-chromium alloy 304. Long-term heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require materials to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.
High temperature oxidation resistance
Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product form.
Physical properties
The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the film heat dissipation coefficient, scale and metal surface condition. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides technical standards for stainless steel plates: high-strength stainless steel plates with excellent corrosion resistance, bending workability, toughness of welded parts, and excellent stamping workability of welded parts and manufacturing methods thereof. Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, appropriate content of Si, Mn, P, S, Al, Ni, and satisfies 12≤Cr Mo 1.5Si≤ 17. The stainless steel plate with 1≤Ni 30(CN) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, 0.006≤CN≤0.030 is heated to 850～1250℃, and then heated at 1℃/s The above cooling rate cooling heat treatment. In this way, it can become a high-strength stainless steel plate with a martensite content of more than 12% by volume, high strength of more than 730MPa, corrosion resistance and bending performance, and excellent toughness of the welded heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of welded parts.
The flame of oxygen and gas cannot cut stainless steel plate because stainless steel is not easy to be oxidized.

Corrosion conditions
1. The surface of stainless steel has accumulated dust containing other metal elements or attachments of foreign metal particles. In humid air, the condensed water between the attachments and stainless steel connects the two to form a micro battery, which initiates an electrochemical reaction , The protective film is damaged, which is called electrochemical corrosion.
2. The surface of stainless steel adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.
3. The surface of stainless steel adheres to containing acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), in contact with condensed water, sulfuric acid, nitric acid, and acetic acid liquid spots are formed, causing chemical corrosion. The above conditions can cause damage to the protective film on the stainless steel surface Damage causes rust.

Preservative
The corrosion resistance of stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure. The main role is chromium. Chromium has high chemical stability, can form a passivation film on the surface of steel, isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.
