What should be paid attention to 05CuPCrNi weather resistant cutting

BBN steel 05CUPCRNI weather resistant hot rolled plates stock: 15*2300*14500, 8*2440*4700, 8*2300*6000, 14*1524*6096, 14*2150*8400, 8*2100*6000, 14*2000*12000, 12*2335*5000, 12*2150*7700, 15*2430*7550, 14*2000*11700, 18*2000*10000, 12*1850*9000, 16*1720*10070, 22*2200*8200, 15*2000*10000, 38*2700*6000, 50*1500*6000, 60*1800*9380, 60*1750*9380, 63*2440*5700, 63*2440*6096, 70*2210*7500,80*1800*6260 .

The company's ESP thin gauge is down to 0.6mm. The thinner the thickness of the 05CUPCRNI weather resistant, hot rolled steel product, the more difficult it is to roll. The thickness will encounter increased load, severe vibration of the rolling mill, difficult shape control, and fluttering of the head during the downdraft. There are many problems such as difficulty in getting bite, which limit the thinnest size that can be rolled by hot rolling. At present, the thinnest gauge of conventional rolling line is 1.2mm, and the thinnest gauge of CSP production line is about 1.0mm. The successful rolling of 0.6mm hot rolled steel product is a milestone in hot rolled steel strip technology.

These grades A709 Grade 36, 05CUPCRNI weather resistant, A709 Grade 50 and A709 Grade 50W are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test (Frequency "P"). Bridge steels can be ordered with plate thickness up to 150mm.

05CUPCRNI weather resistant, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
