The use of p275nh material is still faced with some problems

A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where p275nh material high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The p275nh material hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.

Compared with thick steel plates, p275nh material, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.

Tempering the important p275nh material welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve p275nh material strength, plasticity and toughness.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate p275nh material EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
