In recent years, in line with the development trend of iron and A514 Gr M alloy steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A514 Gr M alloy steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
SA516 Gr65 sheet is a carbon steel plate for medium and low temperature pressure vessels. It implements the ASME standard of the American Standard. It can provide a minimum thickness of 8mm and a width of 1500~4000mm. The A514 Gr M alloy steel plate product thickness direction (Z-direction) resistance to tearing and wet hydrogen sulfide corrosion can be added Performance (HIC+SSCC) steel. Steel used to manufacture pressure vessels for petrochemical, gas separation and gas storage and transportation equipment.
Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The A514 Gr M alloy steel plate metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other A514 Gr M alloy steel plate alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary A514 Gr M alloy steel plate carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and A514 Gr M alloy steel plate steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and A514 Gr M alloy steel plate medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. A514 Gr M alloy steel plate, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
