Oil Tempered Chrome Vanadium Commercial Quality

Oil Tempered Chrome Vanadium Spring Wire for Commercial use

ASTM A231

Chromium vanadium is a popular alloy steel for springs that must withstand a large number of operating cycles. Chrome vanadium springs can be used at extremely high stresses in applications where they will also be subject to extreme shock and impact loading.
