What is S355ML hollow section ASTM equivalent

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, S355ML hollow section and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the S355ML hollow section product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.

S355ML hollow section, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.

According to the type of production, boiler tubes can be divided into seamless steel tubes and welded steel tubes. Boiler tubes are mainly used in pipelines, heating equipment, machinery industry, petroleum geological exploration, chemical industry and other fields. Because of the special purpose of the boiler tubes, the technical parameter requirements of the S355ML hollow section, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide S355ML hollow section cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about S355ML hollow section ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
