Product Description
1）Classification: This is an American Welding Society (AWS) standard for a bare stainless steel filler metal classified as martensitic.
2）Composition: The "ER410" classification indicates a nominal composition of 11.5-13.5% chromium, with low carbon content, and a small percentage of manganese and silicon.
3）Application: Its primary use is for welding similar martensitic stainless steels, such as Type 410 and 420, which are known for their hardenability.
4）Properties: The weld metal is air-hardening and, as-welded, it produces a martensitic structure that is very hard and brittle. To achieve adequate toughness and ductility, it requires specific heat treatments.
5）Heat Treatment: A key feature of this filler metal is the need for a preheat of 150-260°C (300-500°F) before welding and a post-weld heat treatment to temper the weld and improve its mechanical properties.
6）Usage: It is commonly used for a wide range of applications, including repairing turbine parts, valve components, and other parts that require good strength, moderate corrosion resistance, and high hardness.

AWS A5.9 ER410 is a martensitic stainless steel filler metal.
It is primarily used for welding similar 12% chromium stainless steel grades and is known for its ability to air-harden.
Martensitic refers to the specific metallurgical structure of the alloy.
When the weld deposit cools, it transforms into a hard and brittle martensite phase, which requires specific heat treatments to achieve ductility and toughness.
Its primary use is for welding similar martensitic stainless steels, such as **Type 410 and 420**.
It's often used in the repair of turbine parts, valve components, and other applications that require high hardness and strength.
ER410 has a nominal composition of **11.5-13.5% chromium**, with a low carbon content.
It also contains small amounts of manganese, silicon, and other elements that contribute to its mechanical properties.
Yes, preheating is absolutely essential when welding with ER410.
A **preheat temperature** of 150-260°C (300-500°F) is generally required to prevent cracking and reduce the thermal shock during the welding process.
After welding, the as-welded martensitic structure is very hard and brittle, making it susceptible to cracking.
A **post-weld heat treatment** (PWHT) is performed to temper the weld, relieving internal stresses and increasing its toughness and ductility.
ER410 is a versatile filler metal that can be used with several welding methods.
It is commonly used for **Gas Metal Arc Welding (GMAW/MIG)** and **Gas Tungsten Arc Welding (GTAW/TIG)**.
The primary benefits are its high hardness and moderate corrosion resistance.
It provides a strong weld joint that can be heat-treated to achieve a wide range of mechanical properties.
ER410NiMo is a low-carbon version of ER410 that contains a small percentage of nickel and molybdenum.
The addition of nickel and molybdenum gives the weld metal better toughness and crack resistance, especially in heavy sections.
ER410 is a staple in the **power generation industry** for welding turbine blades and valve trim.
It is also used in the **petrochemical industry** and in the fabrication of various equipment requiring high hardness.
The tensile strength of an ER410 weld varies greatly depending on the post-weld heat treatment.
In its as-welded condition, it can be very high, but post-weld tempering is necessary to achieve the desired combination of strength and ductility.
For Gas Metal Arc Welding (MIG), a shielding gas mixture of **98% argon and 2% carbon dioxide** is a common and effective choice.
This combination provides a stable arc and good bead appearance.
The exact procedure depends on the specific application, but a typical PWHT involves heating the part to a temperature between 620-760°C (1150-1400°F).
This tempering process relieves internal stresses and improves the ductility of the weld.
The chromium content in ER410 forms a passive oxide layer on the surface of the metal.
This provides moderate corrosion resistance, but it is not as resistant as the higher-alloyed austenitic grades like ER308 or ER316.
ER410 is generally not recommended for welding dissimilar metals.
The high carbon content and air-hardening properties can lead to cracking and brittleness when joined with other alloys.
To prevent contamination and moisture absorption, the wire must be stored in a **clean, dry, and sealed environment**.
It is crucial to keep spools in their original sealed packaging until use.
ER410's high hardness and wear resistance make it a great choice for valve trim and seats.
It can withstand the erosive and corrosive effects of flowing media, ensuring a longer service life for the components.
Welding thick sections with ER410 requires careful control of the preheat and interpass temperatures to prevent cracking.
A thorough post-weld heat treatment is also essential to ensure the entire weld has the desired mechanical properties.
ER430 is a ferritic stainless steel with higher chromium content (15-17%) and is non-hardenable.
In contrast, ER410 is martensitic and hardens on cooling, making it suitable for applications where high hardness is a requirement.
Using ER410 without a proper post-weld heat treatment is not recommended.
The as-welded deposit is very brittle and prone to cracking, which could lead to catastrophic failure in service.
