Carbon Steel 1030


1030 steel is generally used in the quenched and tempered condition for strength. Applications include machinery parts where strength and hardness are requisites.


Formability of 1030 steel in the annealed condition is good.


1030 steel may be welded by all methods. In heavy sections it is advisable to pre-heat at 300 to 500 F and post-heat at 1100 to 1200 F for welding.

Heat Treatment

Heat treat at 1500 to 1600 F and water quench, followed by a tempering treatment.


Forge at 2300 to 1800 F.

Hot Working

Hot work at 900 to 200 F.


A full anneal is accomplished at 1600 to 1800 F followed by slow cooling in the furnace. a stress relief anneal may be done at 1000 F.
