Quality carbon structural steel (GB/T699-1999)
The SCH 20 seamless steel pipe, in addition to containing carbon (C) element and contains a certain amount of silicon (Si) (generally not more than 0.40%), manganese (Mn) (generally not more than 0.80%, deoxidation higher can to 1.20% ) alloying elements, without other alloying elements (except for residual elements). Such steel must also ensure that the chemical composition and mechanical properties. Sulfur (S), phosphorus (P) content of impurity elements is generally controlled at 0.035% or less. Control 0.030% called high-quality steel grades "A" should be added later, for example 20A; the P control 0.025% 0.020%, S control, said the premium-quality steel, the grade should be followed plus the "E" to show the difference. For other residual alloying elements from the raw material into a steel, such as chromium (Cr), nickel (Ni), copper (Cu), etc. The content of the general control Cr ≤ 0.25%, Ni ≤ 0.30% Cu ≤ 0.25%. Some grades of manganese (Mn) content of up to 1.40%, known as manganese steel.
SCH 20 seamless steel pipe weight formula: [(OD - Wall Thickness) * thickness] * 0.02466 = kg / m (weight per meter)
Outer diameter of 10mm-426mm
