Alumina Ceramics:
The growth rate of fixed asset investment in the alumina ceramic steel industry has dropped significantly. From January to June 2013, the investment in fixed assets in the iron and steel industry was 303.5 billion yuan, a year-on-year increase of 4.3%, of which the investment in ferrous metal smelting and rolling was 235.6 billion yuan, a year-on-year increase of 3.3%, and a decrease of 6.1 percentage points from the same period in 2012; The selected investment was 67.9 billion yuan, an increase of 7.8% year-on-year, and the growth rate dropped sharply by 15 percentage points. Reference formula for stainless steel plate/steel belt: stainless steel plate weight (kg) = length (m) * width (m) * thickness (mm) * density ρ (g/cm³).
Stainless steel round bar/wire reference formula: stainless steel round bar weight (kg)=(diameter (mm)/2)*(diameter (mm)/2)*π*length(m)*density ρ(g/cm³)/1000 .
Reference formula for stainless steel round pipe: stainless steel round pipe weight (kg)=((outer diameter (mm)/2)*(outer diameter(mm)/2)-(inner diameter(mm)/2)*(inner diameter(mm)/ 2))*π*length(m)*density ρ(g/cm³)/1000; **wall thickness(mm)=(outer diameter(mm)-inner diameter(mm))/2.
Stainless steel square tube reference formula: stainless steel square tube weight (kg) = (section length (mm) * 2- section width (mm) * 2- wall thickness (mm) * 4) * wall thickness (mm) * length (m) *Density ρ(g/cm³)/1000.
Reference formula for stainless steel equilateral angle steel: stainless steel equilateral angle steel weight (kg) = (section side length (mm) *2-side thickness (mm) * length (m) * density ρ(g/cm³)/1000; **[ 1] According to the national standard for equilateral angle steel GB/T706-2008, the calculation formula for the actual weight of angle steel is more complicated. Because GB/T706-2008 specifies the inner arc radius (r1) and inner arc radius ( r) Not as a delivery condition, this reference formula is given based on the actual delivery status of the angle steel in production and circulation; [2] According to the calculation formula for the section area of the equilateral angle steel given in GB/T706-2008: S=d* (2*bd)+0.215*(r²-2r1²), the theoretical weight of precise stainless steel equilateral angle steel (kg) = cross-sectional area S (mm²) * length (m) * density ρ(g/cm³)/1000.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
