310S stainless steel heat-resistant steel bar


310S heat-resistant steel as aerospace, chemical industry, an important material, is widely used in high temperature environment. High temperature oxidation is the most common and most important form of corrosion damage at high temperature. Therefore, research and development of new materials with high temperature oxidation resistance are of great significance to China’s aviation industry, chemical industry and national defense cause. Austenitic heat-resistant stainless steel 310S (0Cr25Ni20) is a high chromium nickel austenitic stainless steel.

Yield strength (N / mm2) ≥205 Tensile strength ≥520 Elongation (%) ≥40 Density 7.93 g · cm-3 Melting point 1398 ~ 1420 ℃.

The role of nickel in stainless steel is in cooperation with the chromium after playing out.

The effect of manganese on austenite is similar to that of nickel. But it is exact, manganese is not the role of the formation of austenite, but because it reduces the critical quenching speed of steel, in the cooling to increase the stability of austenite, inhibition of austenite decomposition, so that the formation of high temperature Austenite is maintained at room temperature. Manganese is less effective in improving the corrosion resistance of steel. For example, the amount of manganese in steel varies from 0 to 10.4%, and the corrosion resistance of steel in air and acid is not changed significantly.


Standard Calculation Formula of Stainless Steel Plate
Steel Product Weight Weight (kg) = Thickness (mm) × Width (mm) × Length (mm) × Density

Density: Steel
7.93: 201,202,301,302,303,304,304L, 305,321
7.75: 405, 410, 420,
7.98: 309S, 310S, 310, 316, 316S, 316L, 347

Stainless steel rods, wire, theoretical calculation formula

★ diameter × diameter × 0.00609 = kg / m (for 410 420 420j2 430 431)
For example: ¢ 50 50 × 50 × 0.00609 = 15.23Kg / m

★ Diameter × diameter × 0.00623 = kg / m (for 301 303 304 316 316L 321)
For example: ¢ 50 50 × 50 × 0.00623 = 15.575Kg / m

◆ square bar wide width × width × 0.00793 = Kg / m

310S stainless steel is austenitic chrome-nickel stainless steel, has a good 310S stainless steel oxidation resistance, corrosion resistance, because the higher percentage of chromium and nickel, making it have much better creep strength, can continue to operate at high temperatures, with Good high temperature resistance. Because of the high content of nickel (Ni) and chromium (Cr), it has good resistance to oxidation, corrosion resistance, acid and alkali resistance, high temperature resistance, high temperature steel pipe dedicated to the manufacture of electric furnace tube and other occasions, austenitic stainless steel The composition of the austenitic stainless steel is based on chromium and nickel based on the addition of molybdenum, tungsten, niobium and titanium and other elements, because of its organization for the face-centered cubic structure, Thus having high strength and creep strength at high temperatures.
