NM450 steel grade name in different countries

SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, NM450 steel grade, SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.

Our company has NM450 steel grade strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply NM450 steel grade deep processing service for products NM450 steel grade like cutting, drilling, bending, welding and grinding.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, NM450 steel grade Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach NM450 steel grade 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual NM450 steel grade production capacity: 3.5 million tons."

With the increase of temperature, the yield limit of NM450 steel grade will decrease monotonically, but the tensile strength of NM450 steel grade will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of NM450 steel grade. Near the blue brittleness temperature, the NM450 steel grade strength increases and the plasticity decreases. The elongation and section shrinkage of NM450 steel grade increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent NM450 steel grade products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the NM450 steel grade technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
