The specific gravity of stainless steel pipe is . The weight = specific gravity of length and width of thickness, and the weight of plate with thickness of stainless steel pipe of mm = m m = kg m (length) m (width) . M (thickness) (specific gravity) = . tons (weight)And stainless steel are molybdenum containing stainless steels. The molybdenum content of stainless steel is slightly higher than that of stainless steel. Due to the molybdenum content in stainless steel, the overall performance of this steel is better than that of and stainless steel. Under high temperature conditions, when the concentration is lower than % and higher than %, so it is usually used in marine environment.safety requirements ,AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, but poor plasticity and weldability.Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable.
