摘要:
Provided is a lubricant composition for seamless steel pipes or tubes working which totally satisfies various properties, such as storage stability, transferability inside an apparatus tube, sprayability to lubricated sites, and property of uniform adhesion to a high-temperature mandrel bar without losing non-carburizability or excellent lubricity to hard-to-work materials suchas 13 chromiumsteel and stainless steel. Prepared is a lubricant composition which has a viscosity property represented by the following approximate expression: . Y = a·X b wherein Y: viscosity (mPa·s),x: shear rate (s -1 ) ; and a: 4000 to 40000 and b: -1.0 to -0.3 while the lubricant composition is stored to be kept still, and a: 1000 to 20000, and b: -1.0 to -0.15 after 90 seconds from the time when shearing a lubricant composition is finished.
