What are the main characteristics of S700MC oiled steel coil plate

Our company's S700MC oiled steel coil plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime ki

Our company's S700MC oiled steel coil plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the S700MC oiled steel coil plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Comparison of stainless steel 304 and 304L: The main difference between 304L and 304 is the carbon content. The carbon content of 304 is less than or equal to 0.08, and the carbon content of 304L is 0.03 max. Secondly, S700MC oiled steel coil plate, 304 stainless steel is a versatile stainless steel, which is widely used in making equipment and parts that require good comprehensive performance (corrosion resistance and formability), and 304L is a variant of 304 stainless steel with a low carbon content, which is used for Welding occasions.

Our company produces ordinary carbon steel S700MC oiled steel coil plate with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a S700MC oiled steel coil plate production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

Hydrogen (H) is the most harmful element in general steel such as S700MC oiled steel coil plate. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
