Q345NQR2 as rolled plate exported to Vietnam

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, Q345NQR2 as rolled plate quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the Q345NQR2 as rolled plate International leading steel materials supplier.

The mechanical properties of Q345NQR2 as rolled plate steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel Q345NQR2 as rolled plate to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.

Because Q345NQR2 as rolled plate, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the Q345NQR2 as rolled plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This Q345NQR2 as rolled plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. Q345NQR2 as rolled plate, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel Q345NQR2 as rolled plate 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.
