CS plate S890 steel density

The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition S890 steel density is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).

Steel prices in Europe are under downward pressure due to temporary shutdowns by auto makers in most of Europe and the disruption of trade flows due to reduced trade activity in the construction and other steel industries. Despite the import safeguard measures adopted in Europe, some key steel prices have reached a three-year low in 2019. At that time, the European market was oversupplied. Despite the import safeguard plan, the imports to the European Union remained at a historical high, and now the S890 steel density and so on steel price is even close to the level of 2009.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product S890 steel density more than 15 years.

Composition characteristics of S890 steel density product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.
