310S stainless steel tube

310S stainless steel pipe is a kind of hollow circular steel, which is widely used in oil, chemical, medical, food, light industry, mechanical instruments and so on. When the bending and torsion strength are the same, the weight is lighter, and it is widely used to manufacture mechanical parts and engineering structures. It is also often used as a conventional weapon, barrel, shell, and so on.

310S is austenitic chromium nickel stainless steel, which has excellent oxidation resistance and corrosion resistance. Because a higher percentage of chromium and nickel, 310S has much better creep strength, and it can continue operation at high temperature, and has good high temperature resistance.


310S (0Cr25Ni20/0Cr25Ni20Si2), heat-resistant stainless steel, domestic brand 0Cr25Ni20, American brand SA213/TP310S, commonly known as 310S, also known as 2520, duplex stainless steel, used for high temperature furnace tube manufacturing. Chemical composition of SA213/TP310S (%):

Ni nickel: 19.00-22.00

Cr chromium: 24.00-26.00

Si Si 1.50

Mn Mn < = 2

C C < = 0.08

S s < = 0.030

P P < = 0.035

The method of making seamless steel pipe and steel used in common at all, "GB14975-94 stainless steel seamless steel tube" rules, by 0Cr13, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr25Ti, 1Cr21Ni5Ti, 00Cr18Ni10, 1Cr18Ni9, 1Cr18Ni9Ti, 00Cr17Ni14Mo2, 0Cr18Ni12Mo2Ti, 1Cr18Ni12Mo3Ti, 1Cr23Ni18, 1Cr18Ni11Nb and other steel production. Use: stainless seamless steel tubes are widely used in petroleum chemical pipes and various uses of stainless and acid resistant steel structure parts, should ensure that the chemical composition and physical properties of steel.

Density: 8 g / cm3, the mechanical properties after solution treatment, the yield strength is more than 205, the tensile strength is more than 520, more than 40 elongation, hardness test: HBS = 187, HRB = 90, HV = 200

310S stainless steel is suitable for making various furnace components, the maximum working temperature of 1200 degrees C, the continuous use temperature of 1150 degrees C.

Weight calculation formula of 310S stainless steel management theory: (outer diameter wall thickness) x wall thickness x 0.02507=KG/M
