S355J2G3 Q345R Channel Beams

S355J2G3 is a European standard steel, the composition is: C ≤0.20, Si≤0.55, Mn ≤1.60, P≤0.035, S≤0.035. The beginning of S is structural steel, 355 means that the minimum yield strength is 355MPa. J2G3 means that the delivery state is normalized, the impact work of -20℃ is 27J, G3 and G4 are the meaning of the characterization of deoxidation mode. S355J2G3 indicates semi-killed steel. Q355D is a low-alloy high-strength steel plate, which is often used in the machinery manufacturing industry For example; Crane, hydraulic press, construction machinery, heavy machinery, bridge structure, head, mechanical parts, steel structure, large forklift, agricultural machinery, etc

1.Products Description

The S355J2G3 Plate material can be described as a non-alloy structural steel, which is manufactured in accordance with the EN 10025:1990 standards. The s355j2g3+n material comes with a high fabricability, and cutting them according to the design requirements of the client is very easy. The s355j2g3 material is also known for showing excellent resistance to corrosion and they can withstand a wide range of severe environments, including both oxidizing and reducing ones.

The 1.0570 S355j2g3 steel grade is also effectively used in the marine industries, as they can resist chloride related stress corrosion cracking and crevice corrosion. The Steel S355j2g3 steel grade also possesses good impact strength, and they are readily weldable. One of the best things about the S355j2g3 1.0570 material is that they can retain their characteristics even at sub-zero temperatures. The S355j2g3n plates are lightweight, durable, and hence they can last really long.

Q345R is a combination of 16Mng, 19 Mng and GB6654-1996, and GB150 specified the thickness range is 3 ~ 200mm. The limit value of the tensile strength with low carbon content and standard is no more than 540Mpa, and it has good weldability, in common conditions cold and hot crack are not easy to form. However, the same as the 20 # carbon manganese structure steel, with large thickness and in low ambient temperature working environment, it produces cold, hot cracks.

Q345R steel contains a certain amount of alloy elements, yield strength tends to be high, Therefore, we should review the real destrength ratio (real yield strength) from the quality guarantee certificate of the steel or the production unit (The ratio of the degree to the actual tensile strength).
