Oil Tempered Chrome Silicon – Commercial Quality
Chrome Silicon Commercial Quality wire is designed for springs that must withstand considerable shock and extreme heat. Chrome silicon can be used at temperatures up to 50°F higher than chrome vanadium. Recommendations for heat treatment: Immediately after coiling, the springs should be stress relieved at about 400°C (750°F) for 30 minutes. After shot peening, the springs should be stress relieved at about 250°C (480°F) for 30 minutes
Oil Tempered Chrome Silicon – Valve Spring Quality
These materials are designed for springs that must withstand considerable shock and extreme heat. Chrome silicon can be used at temperatures up to 50°F higher than chrome vanadium.
Valve spring quality chrome silicon has been eddy current tested to assure the finest possible surface in keeping with automotive industry requirements.
Valve quality Chrome Silicon conforms to ASTM-A-877.
Oil Tempered Chromium – Vanadium Wire Commercial Quality
Chromium-vanadium is the most popular alloy steel for springs that are required to withstand a large number of operating cycles. It is medium carbon steel with chromium and vanadium added to increase its hardness and tensile strength. The pre-tempered material is best for valve or gun springs. Springs can be used at extremely high stresses in applications where they will also be subject to extreme shock and impact loading. For springs of high endurance, the alloy is usually used at a hardness of Rockwell C44-49. Where extreme stresses and short life are expected, the hardness is increased to Rockwell C50-53.
Oil Tempered Chrome Vanadium – Valve Quality
These materials are designed for springs that must withstand considerable shock and extreme heat. Valve spring quality chrome vanadium has been eddy current tested to assure the finest possible surface in keeping with automotive industry requirements. Valve quality Chrome Vanadium conforms to ASTM-A-232.
