Тот баспайтын болаттың 302 маркасы: құрамы, қасиеттері және қолданылуы

Have you ever wondered what materials are used to make various stainless steel products we use in our daily lives, such as tableware, building materials, medical equipment, etc.? Why can they resist corrosion and remain bright and new? Today, we are going to explore a very common баспайтын болат түрі - 302 маркалы тот баспайтын болат. Let’s enter the magical material world together and see how 302 stainless steel plays a role in our lives.

What Is the Chemical Composition of Grade 302 Stainless Steel?

302 баспайтын болаттың химиялық құрамы келесідей:

1. Carbon (C): up to 0.15%
2. Silicon (Si): up to 0.75%
3. Manganese (Mn): up to 2.00%
4. Phosphorus (P): up to 0.045%
5. Sulfur (S): up to 0.030%
6. Хром (Cr): 17.00-19.00%
7. Никель (Ni): 8.00-10.00%
8. Nitrogen (N): up to 0.10%

302 маркалы тот баспайтын болат мүшесі болып табылады аустенитті баспайтын болат family, characterized by its high content of chromium and nickel. The addition of chromium and nickel gives 302 stainless steel its corrosion resistance, as well as enhanced ductility and strength. The low carbon content of 302 stainless steel makes it less susceptible to sensitization and corrosion in welded structures. The addition of nitrogen helps to improve the material’s strength and corrosion resistance.

What Are the Mechanical Properties of Grade 302 Stainless Steel?

Механикалық қасиеттері 302 маркалы тот баспайтын болат depend on factors such as heat treatment, cold working, and the specific grade of the material. However, the following are some typical mechanical properties of annealed 302 stainless steel:

1. Беріктік шегі: 515 МПа (75,000 дюйм)
2. Өнімділік күші: 205 МПа (30,000 дюйм)
3. Ұзартылу: 40%
4. Hardness (Rockwell B): 92

Please note that these values apply to annealed 302 stainless steel and may vary depending on the material undergoing different heat treatment or cold working processes.

What Are the Applications of Grade 302 Stainless Steel?

302 stainless steel is a common grade of stainless steel with a wide range of applications in various industries. Here are some common uses of 302 stainless steel:

1. Бұлақтар: 302 stainless steel is often used to make springs due to its high strength, good ductility, and corrosion resistance.
2. Бекіткіштер: 302 stainless steel is often used to manufacture bolts, screws, and other fasteners due to its corrosion resistance and strength.
3. Тамақ өнімдерін өңдеуге арналған жабдықтар: 302 stainless steel is commonly used in the manufacture of food processing equipment due to its corrosion resistance, colorfastness, and high-temperature resistance.
4. Medical devices: 302 stainless steel is used in the manufacture of surgical instruments, catheters, and implants due to its biocompatibility and corrosion resistance.
5. Автокөлік компоненттері: 302 stainless steel is used in the manufacture of exhaust systems, brake components, and fuel tanks due to its corrosion resistance and high-temperature strength.
6. Aerospace components: 302 stainless steel is used in the aerospace industry to manufacture aircraft engine components, landing gear, and structural components due to its strength and corrosion resistance.
7. Chemical processing equipment: 302 stainless steel is used to manufacture tanks, pipelines, and valves for chemical processing equipment due to its corrosion resistance and high-temperature strength.

These are just some common uses of 302 маркалы тот баспайтын болат, and its versatility makes it suitable for many other applications.

What Are the Characteristics of Grade 302 Stainless Steel?

302 stainless steel is a grade of austenitic stainless steel, which is a particularly corrosion-resistant and stain-resistant type of stainless steel. Here are some characteristics of 302 stainless steel:

1. Коррозияға төзімділік: 302 stainless steel has strong corrosion resistance, especially in mildly corrosive environments. It can also withstand oxidation and scaling at high temperatures.
2. Күшті: 302 stainless steel has good strength and toughness, able to withstand high stresses and loads without deformation or breakage.
3. Икемділік: 302 stainless steel has ductility, which means it can easily be formed into various shapes without cracking or breaking.
4. Магнетизм: 302 stainless steel is non-magnetic in the annealed state, but slightly magnetic after cold working.
5. Жылу кедергісі: 302 stainless steel can withstand high temperatures, suitable for applications that require heat resistance.
6. Беттік қабат: 302 stainless steel can be polished to a high surface finish, making it suitable for decorative applications.
