S480451-032 - Hobart Sterling AP 310 Stainless Stick Electrode 5/32 E310-16

High-Performance E310-16 Stainless Steel Electrode

The Hobart Sterling AP 310 is a premium quality stick electrode designed specifically for the welding of AISI 310 stainless steels. Engineered to deliver exceptional performance in high-temperature environments, this electrode deposits a weld metal consisting of approximately 25% Chromium and 20% Nickel. This specific alloy composition provides outstanding resistance to oxidation and corrosion at elevated temperatures, making it suitable for service conditions up to 2100°F (1150°C). It is the ideal consumable for industrial applications where thermal cycling and extreme heat are constant factors.

Beyond its primary application for 310 stainless, the Sterling AP 310 is highly effective for joining steels with 20-27% Chromium and 18-22% Nickel. It also serves as an excellent transition layer for welding highly restrained joints in high-carbon steels or for joining dissimilar metals where a ductile, crack-resistant bead is required. The electrode features a rutile-based coating that ensures a smooth, stable arc with minimal spatter, allowing for high-quality deposits even in difficult positions.

Operational Excellence

Welders appreciate the Sterling AP 310 for its user-friendly characteristics. It operates efficiently on both AC and DCEP currents, providing flexibility depending on the available power source. The slag system is designed to be self-peeling or easily removable, which significantly reduces cleanup time and improves productivity during multi-pass welding operations. Whether used for fabrication or maintenance repair, this electrode delivers consistent mechanical properties and X-ray quality welds.

Primary Industrial Uses

This electrode is a staple in industries that manage high-heat processes. It is frequently used in the fabrication and repair of furnace parts, heat treatment baskets, cement kilns, and radiant tubes. In the petrochemical and power generation sectors, it ensures the longevity of components subjected to hot gases and oxidizing atmospheres. The 5/32" diameter is particularly well-suited for filling larger joints and heavy-wall components efficiently.
