    摘要： The pipe end correction method for correcting an inner diameter of pipe end of a seamless pipe made of a high Cr stainless steel containing 8 to 35 mass % Cr, and 0.1 to 10 mass % Ni includes a pipe end correction step following hot tube-making and heat treatment, that forces a plug into the inside of pipe end portion for inner diameter correction so as to expand the pipe end portion while oxide scale, which is generated during tube-making or heat treatment, remains accumulated on an inner surface of the pipe end portion. A lubricant film forming step, prior to the pipe end correction step, applies lubricant at least either on the inner surface of the pipe end portion of the seamless pipe or on a surface of the plug. Seizure flaws can be prevented on the inner surface of the pipe end portion of the high Cr stainless steel.

    摘要： The invention provides a water-soluble metal-working oil agent, including a component A, a component B, a component C, and a component D, wherein the component A is an ester compound which has a characteristic temperature, as measured in accordance with JIS K2242, of 570° C. or higher and which is contained in the water-soluble metal-working oil agent in an amount of 10 mass % or more with respect to the entire amount of the agent; the component B is at least one condensed fatty acid which is selected from a condensed fatty acid (1), produced through dehydration condensation of a hydroxycarboxylic acid, and a condensed fatty acid (2), produced through dehydration condensation of an alcoholic hydroxyl group of the condensed fatty acid (1) with a monovalent carboxylic acid, which has a characteristic temperature, as measured in accordance with JIS K2242, of 650° C. or higher, and which is contained in the water-soluble metal-working oil agent in an amount of 7.5 mass % or more with respect to the entire amount of the agent; the component C is a carboxylic acid which is contained in the water-soluble metal-working oil agent in an amount of 2 mass % or more with respect to the entire amount of the agent; and the component D is a basic compound contained in such a neutralization equivalent that at least the component B and component C are neutralized to cancel out the sum of the acid values thereof. The agent can provide excellent workability with a hard-to-work material and can prolong tool life.
