GMAW
  • AUSTENITIC STAINLESS STEELS
316H

Description

Solid wire for 316/316H materials used at elevated temperatures
These wires are designed to match 316/316H austenitic stainless steels for elevated temperature. Carbon content in the range of 0.04%–0.08% provides higher strength at elevated temperatures. This consumable is suitable to weld 321/321H and 347/347H. Typical applications include steam pipes, furnace parts and components for petrochemical plants and for power stations. Typical service temperatures are 500°C to 800°C.

Description

Application

Developed for welding austenitic stainless steels such as 316/316H in demanding high-temperature environments (500-800°C) with prolonged exposure to creep, these consumables are versatile for welding 321/321H and 347/347H grades in high-temperature structural applications. Particularly crucial in robust weldments with significant constraints, the incorporation of more ductile weld metal minimizes the risk of premature service failure attributed to intergranular HAZ cracking when compared to using 347H. Widely employed across the petrochemical industry, these consumables find essential application in steam piping, superheater headers, furnace parts, and specific components within gas and steam engine turbines. Their usage extends to fossil and nuclear-fueled power stations. Similar to 308H, these consumables require no preheating, maintain a maximum interpass temperature of 250°C, and do not necessitate post-weld heat treatment.

Alloy Type

High carbon 316 austenitic stainless steels.

Microstructure

Austenite with delta ferrite typically controlled in the range 2-8FN.
