C35 E Material is equivalent to A36 or S235/S275/S355 JR

[Gregorydas]

Which material grade in the below list is equivalent to C35 E ?

ASTM A36
S275 JR
S235 JR
S355 JR


I want to know, if this material is any special grade or just normal carbon steel as in the above list.???


{please help}

Hi Gregorydas,

All the materials are carbon steels for structural purposes, but there are some differences among them.

C35E has a controlled composition (about 0.35% C and max 0.035% S) and average mechanical properties that make it suitable for a wide range of applications, mainly in the machinery industry (forgings, seamless tubes, and moderately high temperature applications such as fasteners and flanges). When higher mechanical properties are needed, it can be quench hardened and tempered, too.

All the other materials in the list are structural steels whose main requirement is a good combination of weldability and nearly isotropic mechanical properties (yield strength ranging 250 MPa for ASTM A36 to 355 MPa for S355JR). Of course as the steel gets stronger it becomes less weldable. They are typically delivered in the normalised (+N) or as-rolled (+AR) conditions.

So, depending on the shape and the application the material is intended for, the differences can be small to fairly perceivable.

Dear Mp87

Thank You for your answer. The material is to be used as a bush (150mm Dia Round Bar - 280mm Long - Machined) for a lifting beam for Crane Girder. The material is not available locally. So we are planning to substitute it with S355 JR or A36 if client allows.

Thank You again
