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.

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-
