usage of NM400 steel plate cold brittleness

India began to implement the national blockade measures on March 25. After two extensions, the national blockade measures have been implemented for nearly 50 days, which has a huge impact on the usage of NM400 steel plate economy. To that end, modi said in a televised speech on the evening of the 12th that India will launch a total of 20 trillion Indian rupees one point eight eight Trillion yuan). This usage of NM400 steel plate is equivalent to 10% of India's GDP.BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China.

The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, usage of NM400 steel plate, and can be used instead of 40CrNi steel.In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate.
