What can i do with a mechanical engineering degree: Textile Properties Of S355 Steel - An Overview

S355 is a non-alloy European measure (EN 10025-2) structural steel, around usually used after S235 where to a greater extent than forcefulness is needed. It got keen weldability together with machinability, allow us encounter to a greater extent than mechanical details of this steel.

Identification of Different S355

south - stands for structural steel

355 - stands for minimum yield forcefulness (though it volition vary based on thickness, refer below department for to a greater extent than details)

Normally S355 volition convey next variation based on affect forcefulness at dissimilar temperatures, equally steel popular off to a greater extent than brittle when temperature drops. If your construction ask to withstand -20°C, it's amend together with safer to lead S355J2.

S355JR - Can withstand an affect set out energy of 27J at +20°C

S355J0 - Can withstand an affect set out energy of 27J at 0°C

S355J2 - Can withstand an affect set out energy of 27J at -20°C

S355K2 - Can withstand an affect set out energy of 27J at -30°C (40J at -20°C)

And old followed past times a missive of the alphabet H, similar S355J2H, hither H stands for hollow section.

S355 Yield Strength

S355 is named based on it's minimum yield forcefulness of 355 Mpa (N/mm2), However the yield forcefulness reduces when yous popular off upwards inwards thickness to a higher house xvi mm for apartment products & hollow sections

Here is the tabular array showing reduction inwards yield forcefulness based on thickness
Up to xvi mm - 355 Mpa
xvi mm < t ≤ xl mm - 345 Mpa
xl mm < t ≤ 63 mm - 335 Mpa
63 mm < t ≤ eighty mm - 325 Mpa
eighty mm < t ≤ 100 mm - 315 Mpa
100 mm < t ≤ 150 mm - 295 Mpa

S355 Tensile Strength

S355 ultimate tensile forcefulness ranges likewise varies based on thickness.
Up to iii mm - 510 Mpa to 680 Mpa
iii mm < t ≤ 100 mm - 470 Mpa to 630 Mpa
100 mm < t ≤ 150 mm - 450 Mpa to 600 Mpa

S355 Density

Density of S355 is 7850 kg/m3 similar all other mild steel

S355 Hardness (Brinell Hardness - HB)

Hardness for S355 J2 ranges from 146 HB to 187 HB

S355 Young's Modulus

S355 Youngs's Modulus is 190 to 210 Gpa, inwards a conservative blueprint popular off for 190 Gpa
