Briefly introduce the composition and performance of 2520 (310S) stainless steel plate

1) good oxidation resistance;

2) wide operating temperature range (below 1150℃);

3) no magnetism in solid solution state;

4) high temperature strength;

5) good weldability.

Scope of application：

310S stainless steel plate is a 25cr-20ni series of high alloy stainless steel, excellent high temperature oxidation resistance, suitable for making various furnace components, the highest temperature 1200℃, continuous use temperature 1150℃. Application: material for furnace and automobile purification device.

310S stainless steel is austenitic cr-ni stainless steel with good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so that has much better creep strength, can continue to work at high temperatures, has good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good resistance to oxidation and corrosion.

310S stainless steel plate

Acid and alkali resistance, high temperature performance, high temperature resistant steel pipe is dedicated to manufacturing occasions such as the electric heating furnace tubes, stainless steel after the increase of carbon content in austenite size, due to its solid solution strengthening effect strength was improved, the chemical composition of stainless steel austenite size features based on chromium, nickel added, tungsten molybdenum, niobium and titanium elements, due to its organization is face-centered cubic structure, and thus has high strength and creep at high temperature strength.

253MA, 309S, 310S high temperature stainless steel plate difference

Heat resistant steel is commonly used in the manufacture of boiler, steam turbine, industrial furnace and aviation, petrochemical and other parts of the industry at high temperatures.

310S 0Cr25Ni20)

Characteristics: 310S stainless steel plate is suitable for making various furnace components, the highest temperature 1200℃, continuous use temperature 1150℃.

Application: material for furnace and automobile cleaning equipment.

253 ma:

Features: 253MA is an Austeniticstainlesssteel, planned for application of required high creepstrength and superior anti-corrosion. Its utilization temperature range is 850~1100℃.

Use:

in addition to the alloying elements chromium and nickel, this brand of stainless steel contains small amounts of RareEarthMetals (REM), which significantly improves its oxidation resistance. Nitrogen was added to improve creep properties and to make the steel fully austenitic. Although the chromium and nickel content is relatively low, this stainless steel has the same high temperature properties as highly alloyed alloy steels and nickel-based alloys in many environments.

Which is better ss304 or ss316?

Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature.
What is good quality stainless steel?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.

What is the difference between 304, 304H and 304L?

In fact, the content of chromium and nickel is 304 stainless steel, and the composition contains 18% chromium (Cr) and 8% nickel (Ni), but the main difference lies in the carbon content.

304L is an ultra-low carbon stainless steel. The carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion. In theory, the effect of stress corrosion resistance is stronger than that of 304, but the effect is not obvious in practical applications. The purpose of reducing carbon and adding titanium is the same, but the smelting cost of titanium-added 321 is higher, the molten steel is thick, and the price is more expensive.

The H in 304H refers to high temperature. High carbon content is the guarantee of high temperature strength. GB150 requires that when austenitic steel is used above 525 degrees, the carbon content should not be less than 0.04%. Carbide is the strengthening phase, especially the high temperature strength. Better than pure austenite.

Among the three, the highest carbon content is 304H, the lowest carbon content is 304L, and the carbon content of 304 stainless steel is between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. The difference in carbon content also causes the price to be different, or the requirements for different uses are also different.

Why is stainless steel so expensive?

Stainless steel is more expensive to produce because of the addition of the variety of alloying elements, such as iron, chromium, nickel, manganese and copper. … The chromium attaches itself to oxygen more readily than iron and thus creates a chromium oxide layer which protects the metal from degradation.
What is the safest stainless steel?
Stainless steel cookware is generally recognized as a safe material for cookware. Any good quality stainless steel, be it 304 or 316 stainless steel, is a better choice than most of the other available materials. For example, coated aluminum pans lose their non-stick over time.
