2mm 4mm 6mm 8mm 10mm thick EN steel grade S275NL material

With high-quality EN steel grade S275NL material steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our EN steel grade S275NL material steel market and improved the control of steel plate production quality.

EN steel grade S275NL material, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).

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 EN steel grade S275NL material, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the EN steel grade S275NL material material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this EN steel grade S275NL material steel grade.

Mechanical Properties A242 steel:ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
