Description

EN 10025 S355JR is a low carbon, high tensile strength structural steel known for its excellent weldability, machinability, and formability. It is commonly used in various construction and engineering applications.

Applications

EN 10025 S355JR is widely used in structural and engineering projects, such as buildings, bridges, towers, machinery, and transportation equipment where high strength and good weldability are required.

Blacksmith Applications

EN 10025 S355JR can also be used by blacksmiths in the production of forged components, such as decorative ironwork, gates, and artistic pieces, where excellent formability and weldability are desirable.

EN 10025 S355JR Forging Temperature

Forging of EN 10025 S355JR steel should be carried out between 1100°C - 850°C, followed by slow cooling in a furnace or insulating material to minimize internal stresses.

EN 10025 S355JR Heat Treatment

EN 10025 S355JR Annealing Temperature

Annealing is typically performed at 850°C - 900°C for a sufficient amount of time, followed by slow cooling in the furnace to relieve internal stresses.

EN 10025 S355JR Normalizing Temperature

Normalizing can be carried out by heating the steel to 900°C - 950°C for a proper soak time, followed by air cooling.

EN 10025 S355JR Hardening Temperature

Hardening is not applicable for EN 10025 S355JR steel, as it is a structural steel mainly used in non-heat treated conditions.

EN 10025 S355JR Tempering Temperature

Tempering is not applicable for EN 10025 S355JR steel, as it is a structural steel mainly used in non-heat treated conditions.

Machinability

EN 10025 S355JR steel has a machinability rating of 60, indicating good machinability with appropriate cutting tools and techniques.

Weldability

EN 10025 S355JR steel exhibits excellent weldability. It can be welded using various welding processes, such as SMAW, GMAW, and FCAW, with appropriate preheating and post-weld heat treatment to achieve desired properties.
