General Information

S355J2 is a micro alloyed structural steel suitable for e.g. mechanical engineering applications. The steel posess a good weldability with max CEV =0.47 for all variants. The steel may be delivered with a controlled silicon content for good galvanazing properties. Below, a number of closely related variants with various impact strength are presented. 

Variant SB9813 is delivered with a closely controlled C-content for predictable properties and with a CEV value of max 0.41.

Variant S355J2(M) is a M-treated variant

Variant S355K2 and S355L4 both show good Impact toughness 

Variant 520M is a M-steel variant of S355J2

Variant 550M is a drawn or peeled version of S355J2
