What is 1.4162?
EN 1.4162 (UNS S32101, LDX 2101, X2CrMnNiN21-5-1) is a manganese- and nitrogen-alloyed lean duplex stainless whose low nickel content decouples its price from nickel markets. It gives 550 MPa yield, 750 MPa tensile and 38 % elongation at 230 HB (21 HRC) and is supplied as annealed, 1D and 2B sheet and plate, cold-drawn bar, cold-worked C800 and C1000 material and cold-worked rebar. Machinability is limited (score 38) and the low-molybdenum chemistry gives a corrosion score of 62 with a 300 °C service ceiling; use 1.4362 or 1.4462 for more severe chloride duty. 1.4162 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,420°C (2,588 °F). 1.4162 has a yield strength of 550 MPa (79.8 ksi) and a tensile strength of 750 MPa (109 ksi) — stronger than 83% of stainless steel grades. Elongation at break is 38% and the elastic modulus is 200 GPa (29 Msi).

Working with 1.4162
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 — frequently asked
What is 1.4162 used for?
1.4162 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?
1.4162 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 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 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 is the maximum service temperature of 1.4162?
1.4162 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.
How much does 1.4162 cost?
1.4162 is a standard-cost stainless steel ($$), cheaper than about 71% 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.
