Performance of stainless steel telescopic tube

Corrosion resistance

The stainless steel plate has the ability to resist general corrosion similar to the unstable Ni-ming alloy 304. Long-term heating in the temperature range of the carbonization degree may affect the performance of alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require materials to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

High temperature oxidation resistance

Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product form.

Physical properties

The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the film heat dissipation coefficient, scale and metal surface condition. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides high-strength stainless steel plates with high-strength stainless steel plates with excellent corrosion resistance, bending workability and welded part toughness, as well as excellent stamping workability of welded parts and their manufacturing methods. Specifically, the content of Si, Mn, P, S, Al, and Ni with C: 0.02% or less, N: 0.02% or less, Cr: 11% or more and less than 17%, appropriate content, and meet 125Cr Mo

1.5Sis17, 1sNi 30 (CN) 0.5 (Mn Cu) s4, Cr 0.5 (NiCu) 3.3Mo ≥ 16.0, 0.006sCN ≤ 0.030 stainless steel plates are heated to 850 ~ 1250 ℃, and then carried out at 1 ℃ / s above Cooling rate cooling heat treatment. In this way, it can become a high-strength stainless steel plate with a martensite content of more than 12% by volume, high strength of more than 730MPa, corrosion resistance and bending performance, and excellent toughness of the welded heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of the welded part.

The flame of oxygen and gas cannot cut stainless steel plate because stainless steel is not easy to be oxidized.
