EN 10025-2 Grade S355JR is a normalized structural steel with minimum yield strength of 355 N/mm2 and tensile strength of 455 N/mm2. It finds widespread application in heavy and transport engineering, machine tool production, power engineering applications as well as bridge building projects.
According to the application, this item comes in various lengths and widths. It can be welded using various methods and coated with various finishes.
This steel has excellent oxidation resistance and is suitable for use in corrosive environments due to its low chromium content and nickel concentrations.
S355JR is an ideal material for fabricating piping systems that transport CO2 flue gases, such as those from coal-fired power plants. It has undergone corrosion tests in a 3.5% NaCl solution plus CO2 at 100 bar and 60 degrees Celsius in an autoclave environment.

A252 is the standard specification for welded and seamless steel pipe piles used to support and reinforce structures like dams, highways, waterways and bridges. It specifies the nominal wall thickness of cylinder-shaped piles as well as maximum and minimum load requirements for these types of constructions.
ASTM A252 is an essential steel standard for pipe piling, outlining the maximum and minimum loads, required tensile strength and yield strength of both welded and seamless steel pipe piles. Additionally, it specifies the design of a load carrying capacity for the structure being installed, the type of piles, required ducting, as well as cement types to fill these piles once in place.
