Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Heavy-coated, flat/horizontal high-deposition type | Use for flat-position build-up and cladding where deposition rate governs; not for out-of-position work. | 390 | 550 | 21 | 19 HRC | 3 % IACS |
Silica-bearing rutile coating, AC or DCEP | Choose for the smoothest bead appearance and best wash-in on fillet and vertical-down welds. | 395 | 555 | 22 | 19 HRC | 3 % IACS |
PWHTDefault Post-weld heat treated | Standard delivery/qualification condition: tempers the martensite for ductility and toughness while meeting AWS A5.4 450 MPa / 20 % requirements. | 400 | 560 | 23 | 20 HRC | — |
Rutile (titania) coating, AC or DCEP, all-position | The most widely stocked coating type: smooth arc, easy slag removal, AC-capable (Chinese old designation G202). | 405 | 565 | 22 | 20 HRC | 3 % IACS |
Lime/basic coating, DCEP only, all-position | Pick for heavier sections and restrained joints where the lowest hydrogen and best deposit toughness are needed (Chinese old designation G207). | 430 | 590 | 24 | 21 HRC | 3 % IACS |
Quenched and tempered | Use when the whole fabrication is re-heat-treated with the 410/CA-15 base metal to give a uniform, refined tempered-martensite structure. | 470 | 640 | 21 | 22 HRC | 3 % IACS |
As-welded deposit | Pick when the overlay is used for hardness/wear and no post-weld heat treatment is possible; expect low ductility and cracking risk in restrained joints. | 600 | 780 | 10 | 41 HRC | — |
Hardfacing overlay, as-deposited and stress-relieved only | Choose for valve seats, seal faces and steam-erosion build-up where maximum as-deposited hardness matters more than weld-metal ductility. | 640 | 800 | 8 | 43 HRC | 2.8 % IACS |
What is E410?
E410 is an air-hardening 13 % Cr martensitic stainless electrode (W41010, E410-16 to GB/T 983) that matches Type 410 base metal and is used for hardfacing, overlay and dissimilar cladding where post-weld heat treatment can be applied. Conditions on file include as-welded, PWHT, quenched-and-tempered and hardfaced deposits in -15, -16, -17 and -26 coatings. Tempered deposit properties are about 400 MPa yield, 560 MPa tensile, 23 % elongation and 200 HB (20 HRC), with service to 650 °C, machinability score 45 and corrosion resistance score 45. The deposit hardens on cooling and needs preheat and temper; use a ferritic electrode such as E430 where PWHT is not practical. E410 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,480°C (2,696 °F). E410 has a yield strength of 400 MPa (58 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 57% of stainless steel grades. Elongation at break is 23% and the elastic modulus is 200 GPa (29 Msi).

Working with E410
Is E410 easy to machine?
Machine only after the 730–760 °C temper; as-welded deposit at ~40 HRC needs carbide or CBN tooling, rigid setups and low surface speed.
Can E410 be welded?
Preheat 200–300 °C, hold interpass 200–350 °C, avoid interruption, and temper at 730–760 °C soon after cooling to ~150 °C to prevent hydrogen/delayed cracking; redry electrodes 300–350 °C for basic types.
Can E410 be formed, bent or molded?
Not a wrought product — deposit is not cold formed; control bead sequence and stringer technique to limit residual stress in thick overlays.
E410 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.

E410 — frequently asked
What is E410 used for?
E410 is typically used for valve seat hardfacing, turbine blade buildup, pump shaft cladding and repair of 410/420 castings. In short: air-hardening martensitic filler; hardfacing and shaft buildup; mandatory preheat and temper.
What is the yield strength of E410?
E410 has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 57% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is E410 easy to machine?
Reasonably — machinability is rated fair (45/100, better than 84% of stainless steel grades). Machine only after the 730–760 °C temper; as-welded deposit at ~40 HRC needs carbide or CBN tooling, rigid setups and low surface speed.
Can E410 be welded?
With care — weldability is rated fair (40/100). Preheat 200–300 °C, hold interpass 200–350 °C, avoid interruption, and temper at 730–760 °C soon after cooling to ~150 °C to prevent hydrogen/delayed cracking; redry electrodes 300–350 °C for basic types.
What surface finishes work on E410?
Grind/blast then passivate or electropolish for a corrosion-resistant surface; chrome or nickel plating and paint adhere well after grit blasting.
Can E410 be formed, bent or molded?
Not a wrought product — deposit is not cold formed; control bead sequence and stringer technique to limit residual stress in thick overlays.
What is the maximum service temperature of E410?
E410 is rated for continuous use to about 650°C (1,202 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E410 PWHT and E410-HF?
PWHT is the default condition — standard delivery/qualification condition: tempers the martensite for ductility and toughness while meeting AWS A5.4 450 MPa / 20 % requirements. HF: choose for valve seats, seal faces and steam-erosion build-up where maximum as-deposited hardness matters more than weld-metal ductility. Yield strength is 400 MPa in PWHT versus 640 MPa in HF.
