Low Temperature Carbon Steel Flanges Supplier in India

For alloys that need to be used at low temperatures, it needs to have certain characteristics to prevent failure. At low temperatures, metals tend to contract - because of the decrease in volume between the atom spaces. In piping systems, contracted spaces caused by components would be inefficient, as they would prove to restrict the flow of media across pipes.

ASTM A350 LF2 Flanges

Therefore, the use of Ltcs Flange permits unrestricted flow while exhibiting high mechanical strength. Carbon steels typically contain a higher content of carbon with iron in their chemistry, which is the primary reason for their economic cost. Unlike alloy steel or stainless steel grades that contain various elements included in their chemical composition, carbon steel components are not suited to be used across applications that involve corrosive compounds or solutions, as they are easily corroded. With an increase in the content of carbon, Low Temperature Carbon Steel Flanges are harder and work well in demanding applications. While grade LF2 works well in cold temperatures, they are segregated into two classes on the basis of minimum applicable temperature. For instance, class 1 under grade LF2 can be used at lower temperatures. In applications where the temperatures reach as low as -50°F, it is recommended to use the A350 Lf2 Cl1 Weld Neck Flange. Produced according to specification ASTM A350, these low temperature carbon steel components need to undergo testing for notch toughness. Heat treatment is carried out on these flange to increase their yield strength as well as their hardness and toughness properties. With moderate strength properties, the ASTM A350 LF2 Flange may often be supplied in a Normalised condition. Apart from being heat treated by normalization, suppliers supply the low temperature A350 Lf2 Slip on Flanges in either a Normalised and Tempered condition or a Quenched and Tempered condition, depending on the requirement of the application.
