ASTM A694
The standards of A694 are more rigorous than the more common SA105N and SA350LF2 grades, providing more robust specifications for high-pressure fluid transmission in oil and gas piping systems. The increased demands on the physical properties of the steel create a stronger metal throughout the pressure range, from low to high temperature services.

 
Each grade in the A694 specification is assigned a number correlating to the minimum yield strength (in ksi units) required for that grade; GradeF52 for example requires a minimum Yield Strength of 52 ksi.
SA105N
This is a mild Carbon Steel that is not only one of the most common of the Carbon steels, but also one of the most common steels in the world. It is hard, not brittle or ductile, and has a low price point. SA105N is very common throughout many industries, and is even used with stainless Steel piping systems with the aid oflap joint End Rings
We stock large diameter (18” – 42”) SLIP-ON, Lap Joint, Weld Neck, and Blind Flanges in SA105N, in class 150 and 300, and can also source a variety of sizes and classes for longer lead times, from 12” to 60”.
SA350 LF2
This is a grade of Carbon Steel intended primarily for low-temperature service and requires notch toughness testing. Very similar to SA105N, this material is used in more industrial applications such as the oil and gas industries.

We can supply large diameter Flanges of all types in SA350LF2, from 18” to 60”, in a wide variety of pressure classes.
The A350 LF2 Line is often referred to as Carbon Steel Low Temp Fittings or Flanges
We carry a large inventory of Carbon Steel Flanges in many types and sizes.
Grades of Carbon steel flanges:
We shall be pleased to develop Non-Standard
· ASTM A105, ASTM A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2
· ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, F70
Carbon Steel Forged Flanges
A flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.
Flanges are manufactured in all the different materials to match the material of the pipe and fittings to which they are being attached. While some flanges are made of Cast Iron, the vast majority of flanges are forged carbon steel.
Forged steel flanges are made in seven primary ratings: Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500 & Class 2500-
Chemical Composition of ASTM A694
ASTM A694 Standard covers carbon and alloy steel forgings for pipe flanges, fittings, valves, and parts for high-pressure transmission service.
