What is 1.4412?
1.4412 (GX5CrNiMo19-11-3) is a cast Cr-Ni-Mo austenitic stainless steel of the CF8M type with molybdenum toward the upper end of the range, which raises pitting resistance in chloride-bearing process fluids. It is used for sand and investment cast pump and valve components, supplied solution annealed and water quenched or HIP'd; typical values are 260 MPa yield, 530 MPa tensile, 38 % elongation and 160 HB with service to 550 °C. Carbon sits at the standard level, so major repair welds on corrosion-critical parts should be re-solution annealed; low-carbon 1.4409 (CF3M) is the alternative for as-welded service. 1.4412 has a density of 7.95 g/cm³ (0.287 lb/in³), heavier than 81% of stainless steel grades. It melts at 1,395°C (2,543 °F). 1.4412 has a yield strength of 260 MPa (37.7 ksi) and a tensile strength of 530 MPa (76.9 ksi) — weaker than 84% of stainless steel grades. Elongation at break is 38% and the elastic modulus is 195 GPa (28.3 Msi).

Working with 1.4412
Is 1.4412 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; avoid dwelling to prevent a hardened skin.
Can 1.4412 be welded?
Very good with GTAW/SMAW using over-alloyed E/ER 19-12-3 (316L-type) filler; no preheat, keep interpass < 150 °C and heat input low, solution re-anneal after major repairs on corrosion-critical parts.
Can 1.4412 be formed, bent or molded?
Cast to shape in sand or investment moulds with generous risering (long freezing range, ~2.3% shrink); cold forming is not a normal route, straightening is done warm.

What surface finishes work on 1.4412?
Pickle and passivate after casting, grinding or welding to restore the passive film; mechanically polishable to a fair finish, electropolishing gives the best pit-free surface.

1.4412 — frequently asked
What is 1.4412 used for?
1.4412 is typically used for chemical process pumps, valve bodies and marine hardware. In short: higher-Mo CF8M variant; better pitting resistance than CF8M.
What is the yield strength of 1.4412?
1.4412 has a typical yield strength of 260 MPa (37.7 ksi) and a tensile strength of 530 MPa (76.9 ksi) — weaker than 84% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4412 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; avoid dwelling to prevent a hardened skin.
Can 1.4412 be welded?
Yes — weldability is rated very good (75/100). Very good with GTAW/SMAW using over-alloyed E/ER 19-12-3 (316L-type) filler; no preheat, keep interpass < 150 °C and heat input low, solution re-anneal after major repairs on corrosion-critical parts.

What is the maximum service temperature of 1.4412?
1.4412 is rated for continuous use to about 550°C (1,022 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4412-AT and 1.4412 AT-HS?
AT is the default condition — standard supply condition for all pressure-retaining castings; maximum corrosion resistance and toughness. AT-HS: thick-wall pump and valve bodies where slower quench gives coarser structure and slightly lower ductility/toughness. Yield strength is 260 MPa in AT versus 245 MPa in AT-HS.
How much does 1.4412 cost?
1.4412 is a premium-cost stainless steel ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
