1Cr13 boiler tube shields are protective components designed to safeguard boiler tubes from erosion, corrosion, and mechanical wear in high-temperature industrial environments. Made from 1Cr13 stainless steel (AISI 410 / X12Cr13), a martensitic stainless alloy with 11.5–13.5% chromium and 0.08–0.15% carbon, these shields offer high strength, excellent hardenability, and moderate corrosion resistance.

These erosion-resistant shields are widely used in power generation, petrochemical plants, refineries, and chemical processing industries, where boiler tubes are exposed to abrasive materials, high-velocity flue gases, and temperatures up to 600°C. The high chromium content enhances resistance to oxidizing environments, while the hardened structure ensures long-lasting wear protection in areas such as superheaters, reheaters, economizers, and water-cooled wall tubes.

1Cr13 shields are commonly paired with other alloys like 1Cr6Si2Mo or TP321 for extended protection in severe conditions. Available in multiple geometries—including straight, curved, in-curve, outer-curve, side-curve, and S-curve—these shields are customizable for tube outer diameters (OD) ranging from 32 mm to 89 mm, such as 38, 42, 48, 57, and 76 mm. Wrap angles typically range from 120° to 180°, with thickness options from 2 mm to 5 mm.

Installation methods include spot welding, clamp-on mounting, or snap ring attachment using stainless clips (C-type or U-type, made from 304 or 310S). Manufactured using high-pressure molds, these shields ensure tight fit, smooth finish, and weldability. Regular inspection and replacement during overhauls (every 3–5 years) help prevent failures and minimize maintenance downtime.
