Working with E410-15
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.
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.

E410-15 — frequently asked
What is E410-15 used for?
E410-15 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 E410-15?
E410-15 has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 590 MPa (85.6 ksi) — stronger than 67% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is E410-15 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 E410-15 be welded?
With care — weldability is rated fair (44/100). 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 E410-15?
Grind/blast then passivate or electropolish for a corrosion-resistant surface; chrome or nickel plating and paint adhere well after grit blasting.
Can E410-15 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 E410-15?
E410-15 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.
