ASTM1566 Spring Steel Round Bar ASTM A29 / A29M-04 bright round bar

Manganese in ASTM1566 improves hardenability, φ 12mm steel can be quenched in oil, and its surface decarburization tendency is smaller than that of silicon steel. The comprehensive mechanical properties after heat treatment are better than that of carbon steel, but it has overheating sensitivity and temper brittleness. ASTM1566 is used for various flat and round springs, seat cushion springs, spring springs of small sizes, and also for making spring rings, valve springs, clutch springs, brake springs and cold-drawn steel wire cold-rolled coil springs.
