Harden steel parts without cracks or distortion. This oil cools slower and more evenly than water for consistent hardening and less scrap.
Match the oil’s cooling rate to your steel’s alloy. Carbon steel and low-alloy steel (less than 5% alloy content) typically require faster cooling. High-alloy steel (more than 5% alloy content) benefits from slower cooling. You'll also need to account for the shape of your part. The more intricate the part, the slower the quench time you should choose.
