Q690D grade is a low-alloy high-strength structural steel, belonging to the structural steel category. Q690D steel plate executive standard: GB/T16270-2009. Q is the expression of yield strength, 690 is its lower limit yield value, and D is its grade. This grade also has a higher yield strength and tensile strength. Q690 series grades also include Q690C, Q690D, Q690E, Q690F. Delivery status of steel S420ML hardness: It should be delivered in quenched and tempered state. In addition, this grade can be delivered according to some special requirements of customers, but it should be indicated in the contract.
S420ML hardness, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., >16-40mm: 345MPa min., >40-60mm: 335MPa min., >60-100mm: 315MPa min., >100-150mm: 295MPa min., >150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
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 S420ML hardness, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades. Whenever there is problem about our S420ML hardness steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.
