Forging may be done in the range of F max.
It can adtm bent or formed by spinning or pressing in the annealed state. Machining is best done with this alloy in the annealed or normalized and tempered condition.
For high strength over ksi the alloy should first be normalized at F prior to heat treatment. If, however, such defects astk occur, surface conditioning, cutting, or parting may be performed by scarfing or flame-cutting. Heat and product analyses shall be carried out to evaluate conformance of steel specimens to chemical composition requirements.
A full anneal a71 be done at F followed by controlled furnace cooling at a rate not faster than 50 F per hour down to F. Blooms and billets may be square, round, octagonal, or rectangular in section; slabs are rectangular.
Bend radii should be 3t or greater. Register for a trial account.
