ASTM A283 Grade A/B/C/D Carbon is moderate, has good comprehensive performance, strength, plasticity and welding performance is good, use the most extensively.
ASTM A283 Grade A/B/C/D used to make steel or factory room, high voltage power transmission tower, Bridges, vehicles, boiler furnace, containers, ships, etc., also a lot less used as performance requirements for mechanical parts, also can be used for some special industry with steel.
