What is the difference between A131 DH40 oil platform steel plate and ordinary strength steel

The company now has A131 DH40 oil platform steel plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than A131 DH40 oil platform steel plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

EN10025-3 S420N material is a welded low alloy steel grade. Its mateiral number is 1.8902. This steel shall be done low temperature charpy V impacting test under EN10025-3 standard, the temperature shall be -20℃, and the impacting energy shall be min 27J. For A131 DH40 oil platform steel plate, S420N steel plate quality, our company will supply various testing for our clients like size and quantity checking, the chemical analysis, ladle analysis, tensile test, impact test, and ultrasonic testing.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A131 DH40 oil platform steel plate is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15~40mm during oil quenching. When the hardness is HB174~229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, A131 DH40 oil platform steel plate.

"A283C is same as A283 Gr C, A283 grade C. A283C plate technical parameters: A283C plate chemical composition - max. 0.24% carbon, max. 0.40% silicon, max. 0.90% manganese, max. 0.035% phosphorus, max. 0.040% sulphuric, and min. 0.20% Cu. A283C plate mechanical properties: min. yield strength is 205 MPa, tensile strength is 380-515MPa, min. elongation is 22% in 8"" and 25% in 2"". Tolerance of A283C plate is subject to ASTM A6. The density of A131 DH40 oil platform steel plate, A283C plate is 7.85g/cm3."

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update A131 DH40 oil platform steel plate stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
