Oil Tempered - ASTM A 229

High-carbon spring steels are the most commonly used of all springs materials. Try to use these materials in preference to others because that are least expensive, readily available, easily worked, and most popular. These materials are not satisfactory for high or low temperatures or for shock or impact loading.
