S355J0W hot rolled sheets vs A283 Grade C

Q370qDNH steel plate atmospheric corrosion resistance steel grade: Q—The first letter of the Chinese pinyin of "qu" for the yield strength of steel used in bridges; 370-a specified value of small yield strength, unit MPa; q-the first letter of the Chinese pinyin of the word "bridge" for bridge steel; D—The quality level is D level; N——The first letter of the Chinese phonetic alphabet of the word "Nei"; H——The first letter of Pinyin of "hou"; Q370qDNH steel standard: GB/T 714-2015.

Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the S355J0W hot rolled sheets, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S355J0W hot rolled sheets. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S355J0W hot rolled sheets is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
