The composition of <>S32168 (06CR18Ni11Ti) is as follows:

06CR18Ni11TI (S32168) belongs to the national standard NB austenitic stainless steel, the executive standard: GB T 1221-2007

The chemical composition of 06Cr18Ni11Ti (S32168) is as follows:

06CR18Ni11TI (S32168) austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automotive industries. However, the "stainless steel" of stainless steel is not absolute, and due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature will have a great impact on the corrosion resistance of stainless steel.

For example, with long-term use in the 450 850 sensitization temperature range, stainless steel will undergo intergranular corrosion. The mechanism is that C combines with the Cr at the grain boundary to form Cr23C6 and precipitate, so that the Cr content at the grain boundary is reduced, which is the so-called "chromium poor". Cr is one of the main elements that inhibit intergranular corrosion, and the probability of intergranular corrosion increases when the Cr content at the grain boundary is less than 12%.

06CR18NI11TI (S32168) Applications include: Oil & Gas Industry Equipment;Offshore platforms, heat exchangers, underwater equipment, firefighting equipment;Chemical processing industry, utensils and pipes;Desalination, high-pressure RO equipment and subsea pipelines;Energy industry such as power plant desulfurization and denitrification FGD system, industrial scrubbing system, absorption tower;Mechanical components (high-strength, corrosion-resistant, wear-resistant).

S32168 is a titanium stabilized austenitic stainless steel, with the addition of titanium to improve the intergranular corrosion performance, and has good corrosion resistance in the atmosphere and in different organic acids and inorganic acids, especially in oxidizing media. This steel also has good mechanical properties at high temperatures. Can be replaced by ultra-low carbon stainless steel.
