DISCUSSION ON CURRENT SITUATION OF DOMESTIC PRODUCTON OF COLD-DRAWN PRECISION STEEL TUBE FOR CYLINDER CASING PURPOSE

The paper covers main areas of domestic industry of cold-drawn precision steel tube,including development of production and manufacturing equipment and the application superiority of the product, particularly the economic superiority in application for making of hydraulic cylinder casing.Although significant development of domestic production of cold-drawn precision steel tubes has been made, there still exist gaps in product variety and quality compared with the industrialized countries. Proposal for further development in this field is also put forward.
