What is Mild Steel? Is it the same as Seamless Steel?

Question

I want to buy steel. My problem is i purchase it from a middle man, so i need to know what MIld steel is. What it's real name or specifications is/are. I dont want to end up purchasing Black steel or other stuff i can sell or use...

Answer 1

Mild steel has a low carbon content. This makes it easier to machine than higher carbon steel, but lowers its strength and hardness. ANSI 1018 is a pretty common type of mild steel. See these links for more information:

Seamless usually refers to a method for making tubing, as opposed to the alloy of steel. Seamless tubing is usually drawn, rather than made from a sheet welded into the form of a tube.

Answer 2

I wonder from your phrasing if you are referring to pipe or tubular steel. Seamless & "Black" usually are terms used when referring to pipe. Mild steel is low carbon steel, easy to machine, form, & weld. It has lower strength than medium or high carbon steels. AISI 1018 is probably the most common. If this "middle man" cannot provide any specifications, maybe you need a new source.

I am a Blacksmith,mild Steel is what I use every Day,I make Ornamental Ironworks,like Handrails,Gate,Candle holders,all kind of things,most things are made from mild Steel,even Buildings,Doors,and so on.No risk of buying it.Special Steel is just for Special Applications.

Answer 4

iron & mild steel are not the same but you need iron to make mild steel this is done by the process off a blast furnace were iron ore coke & limestone are added coke is coal which has been put into a coking oven to remove some impurities then once the coke, iron ore & limestone are mixed this and comes out the bottom of the blast furnace red hot is know as pure iron once you have this you then put it into the BOS Basic Oxygen Steel making were pure oxygen is blown onto the the iron for about 45 min which then turns the iron into steel. hope this helps :o)

Answer 5

Mild steel is an alloy of steel containing Iron and up to 0.3-0.4% Carbon, with minor impurities as manganese etc.

No, it is not same as seamless steel. Seamless is a form/shape of steel (eg. seamless tube, a tube without axial joint or welding, which could be made out of mild steel).

There are several grades of mild steel which you can see from ASTM standard. "www.matweb.com" is a fantastic site which gives free info on various material grades.

Answer 6

mild steel is a kind of steel that have very little carbon . it has no high strenght but seamless is connected to a kind of steel pipe that have no seam because of special method of manufacturing.
