Corten Steel Specification

It’s important to note that in addition to these specifications, the specific grade of corten steel being used, as well as the thickness and size of the material, should also be considered when selecting and working with corten steel. 


Covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction with atmospheric corrosion resistance.

ASTM A606-4

Covers high-strength, low-alloy, hot-rolled, and cold-rolled steel sheets and strips with improved atmospheric corrosion resistance.


Covers cold-formed welded seamless, high-strength, low-alloy structural tubing with improved atmospheric corrosion resistance.

ASTM A709-50W

Covers high-strength, low-alloy structural steel shapes, plates, and bars with improved atmospheric corrosion resistance.

Techniques for Welding Weathering Corten Steel: TIG, MIG, and Stick Welding

When welding weathering corten steel, it’s essential to use the proper technique for the job. TIG welding is best for thinner materials and delicate, detailed welds, while MIG welding is ideal for thicker fabrics and solid and smooth welds. 

TIG Welding

TIG welding is a precise and clean technique well-suited for thinner materials.

It uses a tungsten electrode to create an arc, which melts the base metal and the filler material, forming a robust and high-quality weld. TIG welding is ideal for creating acceptable, detailed welds on weathering corten steel.

MIG Welding

MIG welding is a faster and more efficient welding technique well-suited for thicker materials. It uses a wire electrode fed through a spool, which melts and fuses the base metal and the filler material.

MIG welding is ideal for creating solid and smooth welds on weathering corten steel.

Stick Welding

Stick welding is a versatile technique used on various materials and thicknesses. It uses a consumable electrode coated in flux, which creates a shield around the arc and prevents weld contamination.

Stick welding is ideal for creating strong, durable welds on weathering corten steel.
