JIS SM400B plates cold bending

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and JIS SM400B plates general weldments that do not need heat treatment.

Phosphorus is a very harmful element in JIS SM400B plates steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of JIS SM400B plates steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
