I wish to know what is mean by "steel" regarding density of material. There are several type of steel, eg. carbon steel, stainless steel, galvanised steel, black steel etc... . so please any body can give me the exact density of steel used in engineering calculations. and also please confirm this value is same for all type of steel. Also please mention about Iron eg. ductile Iron, cast Iron, wrought Iron etc..
In Mcgraw hill's Mechanical Engineers Handbook the densities given is different for all type of steel and Iron. But In some table like, ANSI b36.10-1959, the table is given for steel pipe. Can anybody tell me what is meant by standard steel and density used in this table, as I found density is different for different pipe size. please clarify

Standard pipe material is typically carbon steel. Stainless steel is more expensive, so its only used if you have a reason (corrosion or crygenic temperatures) that justifies it.
Most normal temperature pipe that I deal with is A-106-B.
When dealing with low temperatures (-29C to -46C) we use A-333-6.
I don't believe there is a significant difference in density between these types of steels, but I don't have the numbers in front of me to prove that.
Most commercial pipe tables will not say the density of the steel as such, but they will provide a weight per length based on the diameter and schedule of pipe. If you are using these wieghts to design pipe-supports, also keep in mind that you need to consider the pipe full of liquid. Usually, that liquid can be water unless you are expecting a more dense fluid. If it's gas piping you should still design for the pipes full of water, in case the piping needs to be hydrotested in place.
