Description

BS EN 10025 S355 steel is a low carbon steel known for its excellent strength, weldability, and impact resistance. It is commonly used in structural and construction applications.

Applications

S355 steel is widely used in building structures, bridges, machinery bases, shipbuilding, offshore structures, and other high-strength applications where weight savings and durability are crucial.

Blacksmith Applications

S355 steel can be used by blacksmiths for creating various tools such as blacksmith hammers, anvils, tongs, chisels, and other applications requiring high strength and toughness.

S355 Forging Temperature

Forging of S355 steel should be carried out between 1200°C - 950°C, followed by slow cooling in a furnace or insulating material to achieve desired mechanical properties.

S355 Heat Treatment

S355 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.

S355 Normalizing Temperature

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

S355 Hardening Temperature

Hardening is achieved by heating the steel to 880°C - 910°C and then quenching in water or oil.

S355 Tempering Temperature

Tempering should be performed between 550°C to 660°C to achieve the desired hardness and toughness.

Machinability

S355 steel has good machinability with appropriate cutting tools and techniques.

Weldability

S355 steel has excellent weldability. It can be easily welded using common welding methods without the need for preheating or post-weld heat treatment.
