Stainless Steel 1.4020
EN 1.4020
1.4020 (X13CrMnNiN18-13-2, type 202) is a European chromium-manganese-nickel-nitrogen austenitic stainless in which manganese and nitrogen substitute for part of the nickel, giving an economical alternative to nickel-rich 3xx grades with comparable corrosion resistance.

What is 1.4020?
1.4020 (X13CrMnNiN18-13-2, type 202) is a European chromium-manganese-nickel-nitrogen austenitic stainless in which manganese and nitrogen substitute for part of the nickel, giving an economical alternative to nickel-rich 3xx grades with comparable corrosion resistance. Solution-annealed material reaches 390 MPa yield, 780 MPa tensile, 50 % elongation and 195 HB (92 HRB), with service to 760 °C; it is supplied as sheet, strip, tube and bar in +AT through +C1000 and 1/4H to FH tempers. Machinability is low (38) and corrosion resistance (52) sits below 304, so avoid chloride-rich or marine exposure; 1.4301 is the direct alternative where pitting resistance or polish durability matters. 1.4020 has a density of 7.8 g/cm³ (0.282 lb/in³), heavier than 50% of stainless steel grades. It melts at 1,400°C (2,552 °F). 1.4020 has a yield strength of 390 MPa (56.6 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 54% of stainless steel grades. Elongation at break is 50% and the elastic modulus is 197 GPa (28.6 Msi).

Working with 1.4020
Is 1.4020 easy to machine?
Treat as a gummy, fast-work-hardening austenitic: rigid setups, positive-rake sharp carbide, heavy constant feed (no dwell), 15–25 % lower speed than 304 and copious coolant.
Can 1.4020 be welded?
Readily welded by GTAW/GMAW/resistance methods with 308L or 309L filler; keep heat input low, avoid arc-length instability that gases off nitrogen, and use low-carbon or stabilised heats for corrosive service.
Can 1.4020 be formed, bent or molded?
Excellent deep-drawing and bending in +AT, but work-hardening rate and springback exceed 304 — expect ~15–25 % higher press loads, allow for interstage annealing on severe draws.
1.4020 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on 1.4020?
Takes BA, No.4 and mirror polishes well; passivate after machining/welding and pickle heat tint, since the high-Mn surface is less tolerant of embedded iron and residual scale than 304.

1.4020 — frequently asked
What is 1.4020 used for?
1.4020 is typically used for kitchenware, architectural trim and general fabrication. In short: low-nickel 304 substitute; higher strength than 304; weaker corrosion resistance.
What is the yield strength of 1.4020?
1.4020 has a typical yield strength of 390 MPa (56.6 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 54% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is 1.4020 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Treat as a gummy, fast-work-hardening austenitic: rigid setups, positive-rake sharp carbide, heavy constant feed (no dwell), 15–25 % lower speed than 304 and copious coolant.
Can 1.4020 be welded?
Yes — weldability is rated good (68/100). Readily welded by GTAW/GMAW/resistance methods with 308L or 309L filler; keep heat input low, avoid arc-length instability that gases off nitrogen, and use low-carbon or stabilised heats for corrosive service.

What is the maximum service temperature of 1.4020?
1.4020 is rated for continuous use to about 760°C (1,400 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4020 +AT and 1.4020-FH?
+AT is the default condition — standard stock condition: softest, most corrosion-resistant, non-magnetic, best for forming and welding. FH: maximum-strength strip for spring clips, shims and blanked flat parts; essentially no forming capability. Yield strength is 390 MPa in +AT versus 1,000 MPa in FH.
