ASTM A350 LF2 Material Specification

What is LTCS Flange?
A LTCS Flange is a low temperature carbon steel material. The flanges are designed to work primarily in low temperature conditions. The SA 350 LF2 blind flange has a fine grain structure and a uniform carbide dispersion.

ASTM A350 LF2 Class 1 vs Class 2
The ASTM A350 LF2 class 1 and 2 are the versatile classes of this grade that can be differentiated on some basic features. The A350 LF2 Cl1 material is designed with a tensile strength between 415 to 585mpa. This material has a minimum yield strength of 205mpa. An A350 Gr LF2 Material has a tensile strength between 485 to 655mpa and shows a minimum yield strength of 250mpa.
The ASTM A350 LF2 class 1 flange has a minimum applicable pressure of -18 degrees C. Similarly, a class 2 flange has a minimum applicable pressure of -46 degrees C. The minimum applicable pressure of the ASTM A350 Gr LF2 socket weld flange is also its Charpy impact test temperature.
What is the difference between ASME and DIN in A350 Flange?
ASME and DIN are two different institutes or organizations who set standards for the A350 flange . The American Society of Mechanical Engineers (ASME) promotes multidisciplinary engineering and sciences around the world. A DIN A350 LF2 spectacle blind flange is a German Institute for standardization. These flanges are part of the ISO member body and have around thirty thousand standards covering every technological field.
What is the difference between A350 Gr LF2 slip on and weld neck flange?
A weld neck and slip on the flange are among the two common types of flanges used in the industry. SA 350 LF2 Cl1 weld neck flange has a long protruding hub or face. These WN flanges can handle higher pressure and temperature media in the system. SA 350 Gr LF2 slip on flanges are most popular among petrochemical projects. These SORF flanges are welded using one or more fillet welds.
