What is the difference between 1018 and SA573 Grade 58 chemical composition steel?

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of SA573 Grade 58 chemical composition steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main SA573 Grade 58 chemical composition production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

In August 2011, the expanded license for the special equipment material manufacturing of SA573 Grade 58 chemical composition steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the SA573 Grade 58 chemical composition manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.

Compared with SA573 Grade 58 chemical composition, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

Oxygen is a harmful element in SA573 Grade 58 chemical composition steel. With the increase of oxygen content, the strength of SA573 Grade 58 chemical composition steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of SA573 Grade 58 chemical composition steel.
