Chromium molybdenum based alloy steel ASTM A182 F11 Flanges have been designed for use in high temperature and high pressure systems involved in industries such as oil and gas, energy, construction as well as the automotive industries. Primarily, our clients prefer using this alloy grade for its important properties, like the ability of the Chrome Moly Alloy A182 F11 Flange to withstand not only high temperature, but also superior resistance to corrosion and tensile strength.

We supply high quality SA 182 Gr F11 Blind Flange in Mumbai, Get A182 GR F11 Alloy Steel Slip On Flange pressure Ratings and Dimensions

Adding molybdenum in chromium steels successfully decreases the creep rate of steel. Also, molybdenum slows down the coagulation and coarsening of carbides in the chromium molybdenum steel ASTM A182 F11 Class 1 flange, which can occur during their use at elevated temperatures. In the case of austenitic grade F11 Alloy Steel Flanges, adding molybdenum improves resistance to pitting as well as crevice corrosion. This is seen in those environments which especially contain highly corrosive compounds like chlorides and sulphur. Chromium, on the other hand, acts as a retardant to oxidation corrosion, when alloyed with the steel A182 Grade F11 Class 2 Flange. This is because chromium reacts to form a passivated, self-repairing chromium oxide layer on these flanges. This passivated oxide layer formed on the Alloy Steel F11 Flanges acts as a barrier against oxidation.

In comparison to mild carbon steel grades, this chrome-moly based SA182 F11 Cl2 Flange prove to be an ideal alloy in times when a higher level of corrosion resistance and tensile strength is required.
