Cause of corrosion pits on nm450 plate impact resistance

The Indian iron and NM450 plate impact resistance Steel Association (ISA) lowered its steel demand forecast for 2020 to 5.1% from 5.1% in February this year. The figure is expected to hit a low of 7.7%. The company said in an official statement that the current share price has fallen sharply due to the huge downside risk. "We expect India's finished steel demand to fall to about 93.7 million tons by 2020, down from 101.5 million tons in 2019." This calendar year, the NM450 plate impact resistance decline was 7.7%, about 8 million tons. " Isa said.

30CrNi3MoV (675) high-strength steel is a new type of high-strength steel newly developed and put into use in China. It is a steel plate for armored vehicles. 30CrNi3MoV steel is developed by V microalloying on the basis of the original Cr-Ni-Mo series low-alloy ultra-high-strength steel, and appropriately adjusting the content of other alloying elements. The milling performance of 30CrNi3MoV steel is poor.

The difference between NM450 plate impact resistance, 10# seamless steel pipe and 20# seamless steel pipe: 1. Chemical composition Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25 2. Mechanical properties 10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our NM450 plate impact resistance office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase NM450 plate impact resistance 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
