2.Chemical composition:

 

Stainless steel plate no. :0Cr18Ni9(0Cr19Ni9) 06Cr19Ni9 S30408.

 

Chemical composition :C: less than or equal to 0.08, Si: less than or equal to 1.0 Mn: no more than 2.0, Cr :18.0~20.0, Ni :8.0~10.5, S: less than or equal to 0.03, P: less than or equal to 0.035 N = 0.1.

 

Folding and 304 l

 

304L is more resistant to corrosion, and 304L contains less carbon.

 

304 widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties;Stamping bending such as hot workability is good, no heat treatment hardening phenomenon (non-magnetic, using temperature - 196 ° C to 800 ° C).

 

After 304L welding or eliminating stress, its anti-grain boundary corrosion ability is excellent;Under the condition of without heat treatment, can also keep a good corrosion resistance, temperature - 196 ° C to 800 ° C.

3.Fold base case:

 

According to the two types of hot rolling and cold rolling, according to the structure of the steel, there are five types: austenite, austenite, iron, iron, martensitic and precipitation-hardening.Requirements can withstand the oxalic acid, sulfuric acid, ferric sulfate, nitrate, nitric acid, hydrofluoric acid, sulfuric acid, copper sulfate, phosphoric acid, formic acid, acetic acid, etc all kinds of acid corrosion, widely used in chemical, food, medicine, papermaking, oil and atomic energy industry, and construction, kitchenware, tableware, automobile, household appliances all kinds of spare parts.

 

Stainless steel plate surface is clean, with high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion.It is a kind of alloy steel which is not easy to rust, but it is not rust free.

 

The stainless steel plate is divided into two kinds of hot rolling and cold rolling, including thin cold plate with thickness of 0.02-4mm and medium thickness plate of 4.5-100mm.

 

In order to ensure that all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties conform to the requirements, prior to delivery steel after annealing, solid solution treatment and aging treatment, heat treatment, 05.10 88.57.29.38 special symbols

 

Corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organization structure, the main function is chromium element.Chromium has high chemical stability, can form passivation film on the steel surface, so that the metal can be separated from the outside, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate.After the passivation film is destroyed, corrosion resistance decreases.

The density of 304 stainless steel is 7.93 g/cm3 austenitic stainless steel is generally used for 304 chromium content (%), 17.00-19.00, nickel content (%)8.00-10.00, 304 is equivalent to our country's 0Cr19Ni9 (0Cr18Ni9) stainless steel.

 

304 stainless steel is a kind of versatile stainless steel material, which is better than 200 series stainless steel materials.High temperature resistance is also good.

 

304 stainless steel has excellent corrosion resistance and good corrosion resistance.

 

For oxidative acid, in the experiment, it is concluded that 304 stainless steel has a strong corrosion resistance in nitric acid with a concentration of less than 65%.Alkali solution and most organic acids and inorganic acids also have good corrosion resistance.


 

Folding general characteristics:

 

The surface of 304 stainless steel plate is beautiful and the use possibility is varied.

 

Good corrosion resistance, durable than ordinary steel.

304 is widely used in household tableware (1, 2), cabinets, indoor pipeline, water heater, boiler, bath crock, auto parts, medical instruments, building materials, chemical, food industry, agriculture, parts of the ship.

 

Corrosion resistant:

 

Corrosion resistance of stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organization structure, the main function is chromium element.

 

Chromium has high chemical stability, can form passivation film on the steel surface, so that the metal can be separated from the outside, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate.After the passivation film is destroyed, corrosion resistance decreases.

 

It is required to withstand the corrosion of various acids, such as oxalic acid, ferric sulfate, nitric acid, nitric acid - hydrofluoric acid, sulfuric acid - copper, phosphoric acid, formic acid, acetic acid, etc.

 

Widely used in chemical industry, food, medicine, paper, petroleum, atomic energy, construction, kitchen utensils, tableware, vehicles, household appliances, etc.
