Overview
ROLLING TECH Rolling Oil is a metal-rolling oil. It is offered in ISO VG 150, ISO VG 320, ISO VG 460.
The specification table lists, for each grade, kinematic viscosity at 40 °C and 100 °C, viscosity index, pour point, flash point and four-ball weld load and acid number, each with its test method. Share operating conditions with our technical team to confirm the grade before supply.
Application
Rolling operations where an oil in ISO VG 150, 320 or 460 is specified; grade choice depends on the mill, the metal and the reduction.
Feature
ISO VG 150: KV40 155 cSt, KV100 18.9 cSt, VI 98, pour point -18 °C; ISO VG 320: KV40 324 cSt, KV100 25.8 cSt, VI 96, pour point -12 °C; ISO VG 460: KV40 468 cSt, KV100 31.5 cSt, VI 95, pour point -12 °C.
Feature
Published kinematic viscosity at 40 °C sits inside the ISO 3448 tolerance (mid-point ±10 %) for ISO VG 150 (155 cSt); ISO VG 320 (324 cSt); ISO VG 460 (468 cSt).
Feature
Besides viscosity, the published data includes four-ball weld load and acid number, flash point (COC) and foaming tendency.
Start from the equipment manufacturer's viscosity recommendation at operating temperature. The ISO VG number is the mid-point kinematic viscosity at 40 °C (ISO 3448), and each grade's published values are listed separately.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
