Heat treatment
Tempering temperature 1900 ° F (1038 ° C) for 30 minutes and cooling below 60 ° F (16 ° C) for complete martensite conversion.
Welding
Successfully welded by conventional arc welding methods. This alloy should not be welded by gas-oxygen welding. If necessary, the use of AWS E / ER630 fill material is recommended.
Mechanical restoration
High strength of rolled steel causes certain difficulties in machining. It should also take into account the high abrasive ability of the steel alloy, Can be treated in an annealed condition. Cutting edges with a special coating should be used.
