Principal Design Features
|
|
This is a higher carbon (0.30%) manganese steel in the plain carbon steel alloy family. It provides greater strength than the lower carbon grades while still retaining reasonable ductility.
|
|
|
Applications
|
|
1030 steel is generally used in the quenched and tempered condition for strength. Applications include machinery parts where strength and hardness are requisites.
|
|
|
Machinability
|
|
Machinabilty of 1030 steel is rated at 70 % that of the 1112 steel considered to be 100% machinable as a reference.
|
|
|
Forming
|
|
Formability of 1030 steel in the annealed condition is good.
|
|
|
Welding
|
|
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.
|
|
|
Forging
|
|
Forge at 2300 to 1800 F.
|
|
|
Hot Working
|
|
Hot work at 900 to 200 F.
|
|
|
Cold Working
|
|
Cold working of 1030 steel in the annealed condition may be don by conventional methods. A full or stress relief anneal may be needed after cold working.
|
|
|
Annealing
|
|
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.
|
|
|
Tempering
|
|
Temper, after heat treat and quench, at 600 to 110 F depending upon strength level desired.
|
|
|
Hardening
|
|
Hardens by heat treatment or by cold working.
