JIS carbon steel SM520C CS plate Vs 1.0038 Steel

Global JIS carbon steel SM520C CS plate crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global JIS carbon steel SM520C CS plate crude steel production decreased to 443.03 million mt, down 1.4 percent year on year。

Generally speaking, the higher the strength of JIS carbon steel SM520C CS plate, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.
