The delamination problem of Q550NH grade

In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the Q550NH grade steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.

Our quality control department will do inspection for details of the steel materials Q550NH grade before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

Types of steel plates our company supply: A36 carbon structural steel plate, A572 low-alloy high-strength steel plate, Q550NH grade, steel plate for bridge, S355 steel plate for building structure, Grade AH36 steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, mould steel plate, steel plate for alloy structure, API 5L Gr.B pipeline steel plate, high-strength high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate.

16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². Q550NH grade, 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and Q550NH grade product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."

We are professional Q550NH grade carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, Q550NH grade EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.
