Standing at a new historical starting point, we adapt to the requirements of supply side CCS A40 bulk ore carrier steel structural reform, adhere to the overall strategy of "innovation driven, quality leading, 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 International leading CCS A40 bulk ore carrier steel steel materials supplier.
The strength of CCS A40 bulk ore carrier steel, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel CCS A40 bulk ore carrier steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
CCS A40 bulk ore carrier steel, Wear resistant steel plate cutting: plasma cutting, carbon arc, grinding wheel saw can be used to cut large area of steel plate into the required shape. In order to reduce the cold crack of wear-resistant steel plate cutting, the wear-resistant steel plate should be preheated when cutting. The thicker the wear-resistant steel plate is, the higher the hardness is, and the higher the corresponding preheating temperature is. The preheating temperature should not exceed 200.
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 A40 bulk ore carrier steel, NM500 wear plate is 70mm.
