The history of OTEVA dates back to the 1930s, when oil-tempered valve spring wire started to be developed in Garphyttan as a technological advancement compared to traditional cold-drawn wire. The first generation, OTEVA 20, was introduced during this period and marked the beginning of the company’s long-term focus on high-performance spring wire.
What makes OTEVA wire particularly valued is its combination of clean material with high tensile strength, excellent fatigue performance, strong relaxation properties, and high material and surface quality. These properties enable springs to operate at engine temperatures and extreme dynamic loads over long periods without losing performance.
Over the years, Suzuki Garphyttan has continued to develop the OTEVA range through advanced steel grades and proprietary manufacturing processes to meet the increasing demands of modern engines and transmissions.
