Tubo y tubería de acero inoxidable AISI 310S

310S stainless steel tube：

Introduction：

310S stainless steel tube is a hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instruments, etc. When the bending and torsional strength are the same, the weight is lighter, and it is widely used in manufacturing mechanical parts and engineering structures. Also commonly used as conventional weapons, barrels, shells, etc.

310s is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of a higher percentage of chromium and nickel, 310s has much better creep strength, can continue to operate at high temperatures, and has good high temperature resistance Sex.

Ingredient content：

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

Ni Nickel: 19.00-22.00

Cr: 24.00-26.00

Si Silicon <= 1.50

Mn Manganese <= 2.00

C carbon <= 0.08

S sulfur <= 0.030

P phosphorus <= 0.035

The manufacturing method is basically the same as the seamless steel pipe. The steel used is in accordance with the rules of GB14975-94 "Stainless Steel Seamless Steel Pipe". 1Cr23Ni18, 1Cr18Ni11Nb and other steel grades are made. 　Uses: stainless acid-resistant seamless steel tubes are widely used in petroleum, chemical industry, pipelines and various stainless steel, acid-resistant steel structural parts, should ensure the chemical composition and physical properties of steel.

Density: 8.0 g/cm3, mechanical properties after solution treatment: yield strength ≥205, tensile strength ≥520, elongation ≥40, hardness test: HBS≤187, HRB≤90, HV≤200

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

310S stainless steel management theory weight calculation formula: (outer diameter-wall thickness)×wall thickness×0.02507=KG/M

Surface features：

The surface of 310s stainless steel pipe is divided into industrial surface and matte surface

A kind of 310s stainless steel tube with matte surface, only the surface has been matt treated. Otherwise, it is the same as the general 310s stainless steel pipe. The disposal method is as follows:

The matt liquid 1:1 is mixed with water to make the working liquid. At normal temperature or heating the electrolyte to 40-50 degrees, hang the lead plate or stainless steel plate on the cathode, fix the workpiece to be electrolytically polished on the anode, then adjust the voltage to about 5 volts, and remove the workpiece after 3-5 minutes of polishing. Complete matt electrolysis technology.

Technical process: chemical degreasing, derusting → water washing → electrolytic matt → water washing → neutralization → water washing → hot pure water washing

310s stainless steel pipe performance characteristics and application scope:

310s stainless steel pipe belongs to a kind of heat-resistant stainless steel, which is mainly used to manufacture high temperature furnace tubes. In addition, 310s stainless steel pipe has higher chromium and nickel content, and its corrosion resistance is better than 304 stainless steel pipe. In nitric acid with an azeotropic concentration above 68.4%, the conventional 304 stainless steel pipe does not have satisfactory corrosion resistance, while the 310s stainless steel pipe can be used in nitric acid with a concentration of 65-85%

The 310s stainless steel pipe has good thermal strength, vulcanization and vulcanization resistance. The use temperature is 1200 ℃, continuous use temperature is 1150 ℃, its heat resistance is much better than 304, 316, 321 stainless steel. Compared with nickel-chromium superalloy and cobalt-chromium superalloy, it has obvious cost advantages.
