What is the main function of JIS carbon steel SM400A CS plate

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, JIS carbon steel SM400A CS plate plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

Features of Q235NHA sheet:Q235NH steel sheet has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving. It has a long service life when used in harsh environments. It has a protective rust layer to resist atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere.

The difference between Q195 steel and 20# steel: JIS carbon steel SM400A CS plate, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.

The basic principle of JIS carbon steel SM400A CS plate, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of JIS carbon steel SM400A CS plate, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
