What is ASTM equivalent of CCS F32 hull steel plate and their difference

The company now has CCS F32 hull steel plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than CCS F32 hull steel plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

ASTM a992 steel CCS F32 hull steel plate is recognized as the most suitable steel for wide flange beam in the world. It contains a variety of alloy elements, such as vanadium, niobium, copper, nickel, chromium and molybdenum, which greatly improve CCS F32 hull steel plate its strength and other properties. For example, the mechanical properties are much better than the tensile strength 65ksi and yield strength 65ksi of a572-50 and A36. Therefore, a992 wide flange beam (H beam) generally replaces a572-50.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of CCS F32 hull steel plate, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

CCS F32 hull steel plate, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of CCS F32 hull steel plate, NM500 wear plate is 70mm.
