Oil Tempered (OTMB) Spring

Material Type: Oil Tempered
Material Group: Carbon Steel Wire

Oil Tempered Springs Description:

At Spring Engineers of Houston, quality is the priority. Therefore, our oil tempered springs are cold formed and heat treated during fabrication. We use oil tempered spring wire that has good shock, impact resistance, and fatigue properties. While still allowing for manufacturing feasability oil tempered springs are a cost-effective, high-value spring solution.
