ASTM A285 is a specification which covers carbon steel plates of both low tensile strength as well as intermediate tensile strength which could be used in the manufacture of pressure vessels and pipes. Steel grade C has been designed for employment in conventional tanks and boilers preferably, in comparison to their use in elevated pressurised vessels because of the lower yield strength of ASTM A285 Grade C.
The plates used to make ASTM A285 Pipe could belong to any of the following categories of steel i.e. - semi-killed, killed, capped, or rimmed steel. These plates are intended for pressure vessels and piping systems involved in fusion-welding. Normally the ASTM A285 Steel Pipe is supplied in an as-rolled condition. The specified steel alloy needs to conform to the required chemical syntheses. The plates used in the production of ASTM A285 grade c pipe, according to the specification need to be administered a tension test. And the pipe specimens need to adhere to the requirements of the mechanical property mentioned here. The good formability and weld-ability properties of this particular carbon steel alloy makes the ASTM A285 Grade C Carbon Steel Pressure Vessel Pipe usable in applications like structural, mechanical & engineering purposes.
