What is minimum yield strength of Q550NH seawater corrosion resistant steel material?

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, Q550NH seawater corrosion resistant steel material steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and Q550NH seawater corrosion resistant steel material carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, Q550NH seawater corrosion resistant steel material, S275N plate is supplied up to 250mm.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with Q550NH seawater corrosion resistant steel material, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

The ability to resist plastic deformation and fracture under the action of external load is called Q550NH seawater corrosion resistant steel material strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.
Ultrasonic testing of 16MnDR steel plates: The Q550NH seawater corrosion resistant steel material plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.

Our company stocks a wide range of hot rolled carbon steel plate distributed globally from our service centers in the U.S., Canada, Mexico, U.K, France, Shanghai, and Singapore. Customers calling for Q550NH seawater corrosion resistant steel material A516 a lot of times are also trying to get their arms around forecast issues. As our customers continue to work on their forecasts, IRON & Steel has options to help you conduct structured forecast reviews and put inventory strategies in place to effectively manage any impact from forecast variability.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
