Product Details
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.
