The company always adheres to the EN10025-4 S355M steel principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great EN10025-4 S355M steel cause. Customers are welcome to visit our company at any time. We are always ready to support you.

BBN steel have large stock of hot rolled plate EN10025-4 S355M steel. Our products are exported to many countries: South Africa, France, Zimbabwe, Egypt, Mexico, Pakistan, Azerbaijan, Trinidad & Tobago,Tunisia, Chile, Angola, Belarus, Sri Lanka, Afghanistan, Turkey, Hong Kong, United States, Bahrain, Brazil, Jordan, Czech Republic, Indonesia, Denmark, Canada, Taiwan, Iran, Tibet, Nigeria, Croatia, Kazakhstan, Poland, Iraq, Yemen, Bolivia, Serbia, Finland, Nepal, Morocco, Ireland, Singapore, Italy, New Zealand, Namibia, Saudi Arabia, Mexico, Qatar, Lebanon, South Korea.

Cold rolled coil products EN10025-4 S355M steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products EN10025-4 S355M steel is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils EN10025-4 S355M steel with different surface roughness can be produced (glossy surface or matte surface, etc.).

Generally speaking, the higher the strength of EN10025-4 S355M steel, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.

13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. EN10025-4 S355M steel, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about EN10025-4 S355M steel pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel EN10025-4 S355M steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
