Decarburization problem on the surface of stainless steel pipes

The service life of stainless steel pipe products is related to the degree of decarburization on the surface of the steel products. For example, the service life of a steel wire rope mainly depends on its fatigue strength and wear resistance.

The special function of stainless steel pipes is

The special functions of stainless steel pipes are: 1. Corrosion resistance: Due to the thin protective film formed on the surface of 316ti stainless steel, although this protective film is about 3 × 10-6 millimeters, it is very strong and even if damaged, it can be regenerated immediately with oxygen around it to prevent rusting. As long as the characteristics of stainless steel are known and used correctly, there is almost no need to worry about rusting under less corrosive conditions such as water pipes or hot water up to 100 ℃. There is also no need to worry about the occurrence of common "rust protrusions" in galvanized steel pipes, such as a decrease in inner diameter or an increase in resistance, which can achieve unobstructed water flow.

Is 316L stainless steel tube magnetic

People often think that magnets can adsorb 316L stainless steel pipes to verify their quality and authenticity. If they do not attract or have no magnetism, they are considered good and well deserved; If the inhaler has magnetism, it is considered a counterfeit product. In fact, this is an extremely one-sided and unrealistic method of identifying faults.

Comparison of Corrosion Resistance between 317L Stainless Steel Pipe and 316Ti Stainless Steel Pipe

317L stainless steel pipes can be corroded by weak corrosive media such as air, steam, and seawater, while 316Ti stainless steel pipes can be corroded by chemical corrosive media such as acid, alkali, and salt.

Susceptibility to intergranular corrosion of ferritic 310S stainless steel tube

Ferritic 310S stainless steel pipes, like austenitic 316L stainless steel pipes, also undergo intergranular corrosion, but sensitization treatment and heat treatment to prevent this corrosion are exactly the opposite of austenitic steel. Ferrite 310S stainless steel pipes experience intergranular corrosion during rapid cooling (such as water quenching) above 925 ℃; This susceptibility to intergranular corrosion (sensitized state) can be eliminated or reduced by short-term tempering at 650-815 ℃, and the effect of heat treatment on intergranular corrosion of Cr17 and Cr18Ni8 stainless steel can be minimized.
