What is 1119?
1119 is a resulfurized free-machining carbon steel (UNS G11190) at the top of the 11xx family for cutting speed, with a machinability score of 95 — close to 100% of the 1212 benchmark. It combines that with moderate case-hardening capability, and default values of 415 MPa yield, 495 MPa tensile, 15% elongation and 143 HB (78 HRB) in HR, CD, stress-relieved, TGP, normalised, annealed and carburize-and-quench-tempered bar. Sulfur content rules out structural welding and cuts transverse ductility; 1117 gives similar case-hardening with slightly better toughness. 1119 has a density of 7.87 g/cm³ (0.284 lb/in³), heavier than 92% of steel grades. It melts at 1,425°C (2,597 °F). 1119 has a yield strength of 415 MPa (60.2 ksi) and a tensile strength of 495 MPa (71.8 ksi) — weaker than 56% of steel grades. Elongation at break is 15% and the elastic modulus is 200 GPa (29 Msi).

Working with 1119
Is 1119 easy to machine?
Outstanding on automatics — high speeds, short broken chips, long tool life; a rating benchmark near 100 % of 1212, best with sharp tools and adequate coolant.
Can 1119 be welded?
Not recommended for structural welds: high sulfur promotes hot cracking and porosity; if unavoidable use low-hydrogen filler, preheat ~150 °C and low restraint.
Can 1119 be formed, bent or molded?
Fair cold formability along the rolling direction only; sulfide stringers cause splitting on tight transverse bends and heading — anneal or use a resulfurized-free grade for severe forming.

What surface finishes work on 1119?
No anodizing; protect with zinc or nickel plating, black oxide, phosphate + oil; inclusions can leave pits after fine polishing or bright plating.

1119 — frequently asked
What is 1119 used for?
1119 is typically used for shafts, pins and carburized parts. In short: near 100% of 1212; free-machining with case hardening; avoid structural welding.
What is the yield strength of 1119?
1119 has a typical yield strength of 415 MPa (60.2 ksi) and a tensile strength of 495 MPa (71.8 ksi) — weaker than 56% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is 1119 easy to machine?
Yes — machinability is rated excellent (95/100, better than 100% of steel grades). Outstanding on automatics — high speeds, short broken chips, long tool life; a rating benchmark near 100 % of 1212, best with sharp tools and adequate coolant.
Can 1119 be welded?
Not readily — weldability is rated poor (25/100). Not recommended for structural welds: high sulfur promotes hot cracking and porosity; if unavoidable use low-hydrogen filler, preheat ~150 °C and low restraint.
What surface finishes work on 1119?
No anodizing; protect with zinc or nickel plating, black oxide, phosphate + oil; inclusions can leave pits after fine polishing or bright plating.
Can 1119 be formed, bent or molded?
Fair cold formability along the rolling direction only; sulfide stringers cause splitting on tight transverse bends and heading — anneal or use a resulfurized-free grade for severe forming.
What is the maximum service temperature of 1119?
1119 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1119-CD and 1119-HR?
CD is the default condition — standard stocked screw-machine bar: best size tolerance, straightness and chip control. HR: cheapest form for larger machined parts where surface finish and size tolerance are recut anyway. Yield strength is 415 MPa in CD versus 235 MPa in HR.
How much does 1119 cost?
