E308T1-1 SS Flux-Cored Welding Wire
Established Year: 1995
Product Type: Stainless Steel Flux-Cored Welding Wire (AWS E308T1-1)
Core Advantages: All-position welding compatibility, excellent corrosion resistance, easy operation, stable mechanical properties
I. Product Overview
E308T1-1 is a CO₂ gas-shielded austenitic stainless steel flux-cored welding wire formulated with 21%Cr-10%Ni alloy. Featuring stable arc, minimal spatter, and neat weld formation, it has become a preferred material in the industrial welding field. Compatible with both manual and semi-automatic welding modes, it has moderate requirements for welders' skills, which can significantly shorten the training cycle. Meanwhile, it supports all-position welding to meet the needs of diverse operation scenarios.

III. Application Scenarios
With both high strength and high corrosion resistance, E308T1-1 stainless steel flux-cored welding wire is widely used in fields requiring strict welding quality, especially suitable for the following scenarios and base materials:
Core Application Fields:
Petrochemical Industry: Welding of transmission pipelines and reaction vessels
Sanitary-Grade Fields: Food machinery and medical equipment (meeting sanitary standards to avoid metal ion contamination)
High-Pressure Equipment Field: Pressure vessels and chemical fertilizer equipment
Special Industrial Field: Auxiliary components of nuclear reactors
Compatible Base Materials: Stainless steel materials such as 12Cr18Ni9 (SUS 302) and 06Cr18Ni10 (SUS 304)
IV. Operation Guide and Precautions
1. Preparation Before Welding
Thoroughly remove impurities such as oil stains, rust, and moisture from the welding area and groove surface, and polish until the metal luster is exposed to prevent defects like pores and cracks during welding.
2. Recommended Welding Parameters
Shielding Gas: Pure shielding gas is recommended, with the flow rate controlled at 20-25L/min
Stick-Out Length: Maintain a range of 15-25mm to ensure arc stability
Current Control: General parameters for all-position welding can be adjusted as needed. Among them, the current for vertical welding/overhead welding should be reduced to 100-140A to ensure the quality of weld formation
3. Important Reminder
The welding methods, conditions, and specifications in the product description are for reference only. Before formal welding, process qualification must be completed according to the characteristics of the equipment and workpiece requirements to ensure process compatibility and safety.
V. Frequently Asked Questions (FAQ)
Q: Is this welding wire suitable for high-temperature environments?
A: It can withstand temperatures of 400℃ for short periods; for long-term operation in high-temperature conditions, it is recommended to use welding wires with higher nickel content (such as E310T1-1).
Q: Can it replace ER308 solid-core welding wire?
A: Yes. Flux-cored welding wire has better process performance, and it performs more outstandingly in terms of efficiency and quality, especially in all-position welding or manual welding scenarios.
Q: Does it support all-position welding?
A: It supports flat welding, vertical welding, horizontal welding, and overhead welding; note that the current should be controlled at 100-140A during vertical welding/overhead welding.
