DIPTIINOX® ER310 TIG Rod (AWS A5.9): Leading Manufacturer & Exporter for High-Heat and Fully Austenitic Welding
Dipti Metal Industries is a Leading ER310 TIG Rod Manufacturer, ER310 TIG Rod Supplier in Mumbai, and ER310 TIG Rod Stockiest in Mumbai, India, specializing in high-performance AWS A5.9 ER310 GTAW filler metal under the DIPTIINOX® brand. This solid wire contains a very high concentration of alloying elements (25% Chromium and 20% Nickel), producing a weld deposit that is deliberately fully austenitic (no delta ferrite). This unique microstructure provides exceptional resistance to oxidation and scaling for high-temperature service applications up to 2000°F (1093°C), making it the primary choice for welding steels of similar composition, notably AISI 310. It is also used for joining certain dissimilar materials that demand high ductility and heat resistance. Due to its fully austenitic nature, welding requires meticulous control over heat input to prevent hot cracking. We are a reliable ER310 TIG Rod Wholesaler and guarantee full conformance to AWS A5.9 for critical industrial applications globally.
DIPTIINOX® ER310: The High-Alloy Solution for Maximum Thermal and Oxidation Resistance
The AWS A5.9 ER310 TIG Rod is characterized by its exceptionally high Chromium (25.0-28.0%) and Nickel (20.0-22.5%) content, which classifies it as a fully austenitic filler metal. This unique, high-alloy composition prevents the formation of ferrite, making the weld deposit incredibly stable and resistant to the detrimental Sigma phase embrittlement that can occur in other stainless steels at high temperatures. As a result, ER310 is the preferred consumable for welding wrought or cast stainless steels of similar composition (like AISI 310) in high-heat industrial furnaces, thermal processors, and kilns. Because a fully austenitic structure is prone to hot cracking, welders must adhere to a process that involves low heat input and strict control over interpass temperature to ensure a sound, defect-free joint.

Primary Applications for DIPTIINOX® ER310 TIG Rod
The ER310 filler metal's high-alloy, fully austenitic structure is specifically suited for high-heat environments and certain challenging metal combinations:
- High-Temperature Equipment: Welding components for industrial furnaces, heat exchangers, muffles, retorts, and annealing boxes (AISI 310 base metal).
- Similar Alloy Welding: Joining wrought and cast versions of Type 310 (25Cr-20Ni) stainless steel.
- Dissimilar Welding: Used as an intermediate layer or final filler metal for some dissimilar joints where high heat resistance is required, and where the dilution from low-alloy steel is minimal or acceptable.
- Heat Resistance: Applications where the weld deposit must maintain strength and integrity without forming brittle phases (like Sigma Phase) after prolonged exposure to elevated temperatures.

ER310 TIG Rod & Wire — Frequently Asked Questions
The ER310 weld deposit is fully austenitic (high Cr/Ni: 25Cr-20Ni) and does not contain ferrite. This fully austenitic structure is required for service at very high temperatures (up to 2000°F or 1093°C) and prevents the formation of undesirable Sigma phase, which can embrittle weld metal at elevated temperatures.
ER310 is primarily used to weld stainless steels of similar high-alloy composition, such as AISI 310 (UNS S31000) wrought or cast materials. It can also be used for certain dissimilar joints, especially when an austenitic buffer layer that is highly heat resistant is required.
The fully austenitic nature of the weld metal makes it highly susceptible to hot cracking. Using low heat input and maintaining a low interpass temperature is critical to minimize the thermal stress and risk of cracking.
The Unified Numbering System (UNS) designation for the ER310 filler metal is UNS S31000.
