Working with 1.4162-ANN
Is 1.4162 easy to machine?
Cuts like a work-hardening duplex: use rigid setups, sharp coated carbide, positive rake, heavy constant feed and flood coolant; cutting speeds roughly 60–70% of 316L and avoid dwelling to prevent surface hardening.
Can 1.4162 be welded?
Weld with GTAW/GMAW/FCAW using over-alloyed 2209/2307-type filler or autogenous only with post-weld solution anneal; keep heat input ~0.5–2.5 kJ/mm and interpass below 150 °C to hold ferrite near 30–70% and avoid nitride/sigma formation.
Can 1.4162 be formed, bent or molded?
Cold forms well but needs about twice the press force of 304 and generous overbend for springback; hot form at 950–1200 °C followed by full solution anneal and quench — never stress-relieve in the 300–1000 °C range.
What surface finishes work on 1.4162?
Pickle (HNO₃/HF) or bead-blast plus passivation after hot work and welding to restore the passive film; electropolishing gives a bright hygienic surface — anodizing is not applicable.

1.4162-ANN — frequently asked
What is 1.4162-ANN used for?
1.4162-ANN is typically used for tanker trailers, structural components, water treatment equipment and building facades. In short: low-nickel lean duplex; price-stable 316 alternative; high-strength structural stainless.
What is the yield strength of 1.4162-ANN?
1.4162-ANN has a typical yield strength of 550 MPa (79.8 ksi) and a tensile strength of 750 MPa (109 ksi) — stronger than 83% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1.4162-ANN easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Cuts like a work-hardening duplex: use rigid setups, sharp coated carbide, positive rake, heavy constant feed and flood coolant; cutting speeds roughly 60–70% of 316L and avoid dwelling to prevent surface hardening.
Can 1.4162-ANN be welded?
Yes — weldability is rated very good (70/100). Weld with GTAW/GMAW/FCAW using over-alloyed 2209/2307-type filler or autogenous only with post-weld solution anneal; keep heat input ~0.5–2.5 kJ/mm and interpass below 150 °C to hold ferrite near 30–70% and avoid nitride/sigma formation.
What surface finishes work on 1.4162-ANN?
Pickle (HNO₃/HF) or bead-blast plus passivation after hot work and welding to restore the passive film; electropolishing gives a bright hygienic surface — anodizing is not applicable.
Can 1.4162-ANN be formed, bent or molded?
Cold forms well but needs about twice the press force of 304 and generous overbend for springback; hot form at 950–1200 °C followed by full solution anneal and quench — never stress-relieve in the 300–1000 °C range.
What is the maximum service temperature of 1.4162-ANN?
1.4162-ANN is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4162-ANN and 1.4162-C1000?
ANN is the default condition — standard supply condition for plate, sheet, bar and welded pipe; balanced ~50/50 ferrite-austenite structure with best corrosion resistance and toughness. C1000: heavily cold-rolled strip for high-strength lightweight sections and straps; limited ductility and reduced formability. Yield strength is 550 MPa in ANN versus 850 MPa in C1000.
