I’ve seen a valve body material specified as 316SS+HF – what does that mean?

What does it mean that the valve body material is 316SS+HF? But what does HF mean in that? Thank you for the help? This post was last edited by marry on 2009-3-25 10:00.]

It indicates that the main material of the valve is 316SS stainless steel, while the valve seat is made of HF. HF (short for HARD FACE) is a type of cemented carbide; in China it is known as STELLITE, and it corresponds to AWS A5.13 ERCoCr-A.

The second floor is the correct answer. SS316 refers to 316 stainless steel, while HF stands for hard face, a type of hard alloy!

16SS+HF is a base material and a surfacing material. HF (short for HARD FACE) is a type of cemented carbide; in China it is known as STELLITE, and it is equivalent to AWS A5.13 ERCoCr-A. This material is generally used in valves
