  • Lubricative stainless steel sheets and pipes and method of producing lubricative stainless steel pipes
    Patent number: 6479152
    Abstract: Lubricative stainless steel sheet and pipe having a chromate film on at least one of the surfaces of a stainless steel sheet or pipe substrate, the chromate film having an amount of adhered Cr of 5 to 100 mg/m2, and, on the chromate film, a lubricant film obtained by applying, on the chromate film, a water-base coating containing (a) a urethane resin of ether-ester type having a skeleton of bisphenol type, a skeleton of ester, and a carboxyl group, (b) an epoxy resin, and (c) a polyolefin wax, and baking the applied coating, the sum of the amount of the urethane resin of (a) and the epoxy resin of (b) being 70 to 95% by weight of the total solids of the coating, the amount of the polyolefin wax of (c) being 5 to 30% by weight of the total solids of the coating, and the lubricant film having a thickness of 0.5 to 5 micrometers and a Vickers hardness of at least 15. A method of producing a lubricative stainless steel pipe is also disclosed.
