Tensile strength of 304 stainless steel plate: national standard properties, tensile strength (MPa) 520.

304 stainless steel plate is widely used in chemical, food, pharmaceutical, papermaking, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household appliances and other parts of the pure source parts.

The surface of stainless steel plate is smooth and clean, with high plasticity, toughness and mechanical strength, and it is resistant to corrosion of acid, alkaline gas, solution and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust-free.

Stainless steel plate is divided into two kinds of hot rolled and cold rolled according to the manufacturing method, including thin cold plate with a thickness of millimeters and medium and heavy plate with a thickness of millimeters.

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and its internal structure, with chromium playing a major role.

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. When the passivation film is destroyed, the corrosion resistance decreases.

Hello dear, glad to answer for you, thank you for your patience! The yield strength and compressive strength of 201 stainless steel and 304 stainless steel are small: the yield point of 201 steel is 275MPa, and the tensile strength is 520MPa.

Specifically, it is sorted out for you as follows: the information of the query shows that the yield point of 201 stainless steel is 275MPa, the tensile strength is 520MPa, and the elongation is 40%: 2, the yield point of 304 stainless steel is 205MP, and the resistance strength is 515MPa and the elongation is 40%.

The simplest and basic difference between the two is the difference in nickel content, 304 stainless steel has a nickel content of up to 8 points, and the corrosion resistance is stronger than that of 201 stainless steel. This also leads to 304 stainless steel pipes** are more expensive than 201, but 201 stainless steel will not rust if the environment is suitable and well maintained. The corrosion resistance of 304 is better than that of 201, and there is also a 301 stainless steel and nuclear trillion steel material in the middle.

The main pressure difference between 201 stainless steel and 304 stainless steel is the manganese content and carbon content in it, these two alloying elements determine the strength (pressure bearing) of stainless steel, and 201 stainless steel has higher manganese content and higher carbon content than 304 stainless steel pipes, but the comprehensive mechanical properties of 304 stainless steel are better. There is a saying that "the pressure tolerance only depends on the wall thickness of the stainless steel pipe", and this sentence is also true, the thicker the pipe, the better the natural pressure tolerance. There is basically no difference between 304 stainless steel pipe and 201 stainless steel pipe, and the surface color, specification and size and even the production and processing technology can be the same.

Then they have substantial differences, the answer is the difference in material, don't underestimate the "material" of the two words of Zen, the role can be particularly large, which is strictly related to the use of the product and the highest level of the product. The difference between 304 stainless steel pipe and 201 stainless steel pipe is mainly manifested in the following two aspects: 1. Chemical composition 304:

C carbon ,si silicon ,mn manganese :cr chromium :,p phosphorus :

n ,s : Ni nickel ::c carbon ,si) silicon , mn manganese :,cr) chromium :, n nitrogen: p phosphorus:

s) Sulfur: Ni nickel: Due to the low nickel content of 201, it is usually used as an alloy of 201, such as adding manganese or nitrogen, so that 201 is more resistant to oxidation and increases corrosion resistance.

2. Mechanical properties 304 Properties: tensile strength 520MPa, yield strength 205-210MPa, elongation 40%, hardness HB187 HRB90 HV200201 Performance: tensile strength:

520MPa, Yield Strength: 275MPa, Elongation: 55 to 60%, Hardness HRB<183N mm2MPa, hope this service can help you.

Stainless steel yield strength (MPa) 170min.

Tensile strength (MPa) 485min, yield strength (MPa) 170min, elongation (%) 30min, area reduction (%) volt height 40min, 205L stainless steel density, hardness HRB<90HV<200HBS<187. Due to its good corrosion resistance, stainless steel allows structural components to maintain their engineering integrity permanently.

Chromium-containing hall stainless steel also combines mechanical strength and high elongation, making it easy to fabricate components to meet the needs of architects and structural designers.

The yield strength and compressive strength of 201 stainless steel are respectively S (yield strength) 205MPa, b (compressive strength) 520MPa; The yield strength and compressive strength of 304 stainless steel are S (yield strength) 215MPa and B (compressive strength) 520MPa respectively. When using these two stainless steel materials, the following points should be noted: (1) establish a clear processing technology and construction structure to ensure that the structure plays an ideal functional effect during the use of the bucket cong; (2) Avoid large deformation tensile stress, so as to reduce the damage of stainless steel materials; (3) Fully consider heat treatment and cold treatment; (4) Adopt appropriate molds to prevent unnecessary deformation; (5) Perform regular inspection and maintenance to maintain the safe and normal state of stainless steel.

Hello, the yield strength and resistance ridge compression strength of 201 stainless steel and 304 stainless steel are different. Generally speaking, the yield strength of 304 stainless steel is 205 MPa and the compressive strength is 515 MPa. Whereas, 201 stainless steel has a yield strength of 260 MPa and a compressive strength of 515 MPa. From this point of view, the yield strength of 201 stainless steel is higher than that of 304 stainless steel, but the compressive strength of 304 stainless steel is higher than that of 201 stainless steel.

This is due to the different chemical composition and physical properties of different materials. In addition, it is important to note that the stainless steel materials produced by different manufacturers may be different, so the specific yield strength and compressive strength may vary.

Hello dear! The yield strength of 201 stainless steel is 205MPa, and the compressive strength and decay degree are 520MPa; The yield strength of 304 stainless steel is 205MPa, the compressive strength of stainless steel and 304 stainless steel are commonly used stainless steel materials

The composition is different: 201 stainless steel contains 17% chromium, while 304 stainless steel contains 18% chromium; 2.Hardness is different:

201 stainless steel has a lower hardness, while 304 stainless steel has a higher hardness; 3.The corrosion resistance is different: 201 stainless steel has lower corrosion resistance, while 304 stainless steel has higher corrosion resistance; 4.

Different: 201 stainless steel is lower, while 304 stainless steel is higher. Therefore, when choosing stainless steel materials, we should choose the appropriate stainless steel materials according to the actual application needs, comprehensively consider the above four aspects.

The yield strength of 201 stainless steel is about 321MPa, and the compressive strength is about 586MPa; The yield strength of 304 stainless steel is about 205MPa, and the compressive strength is about 517MPa, which can be seen that the yield strength and compressive strength of 201 stainless steel are much higher than that of 304 stainless steel. Stainless ridge steel materials are most commonly used in workpieces involving high strength and corrosion resistance, and are widely used in the aviation, shipwrecking, power generation, combing, and manufacturing industries. At room temperature, stainless steel can be modified by various treatment techniques such as exothermic, welding, and cold deformation, so as to make it more suitable for the use and requirements of the workpiece.
