Böhler Union ER 80S-B2 1.25Cr-0.5Mo TIG Welding Rod
Description
1.25Cr-0.5Mo TIG rod for creep-resistant steel and castings
Böhler Union ER 80S-B2 is a copper-coated solid filler rod for manual gas tungsten arc welding, classified AWS A5.28 / SFA-5.28 ER80S-B2 and EN ISO 21952-B 1CM. The 1.25 % Cr – 0.5 % Mo weld metal has a bainitic microstructure with favourable mechanical properties in tempered and in quenched and tempered condition, and in some cases it can be used as-welded. It covers joint welding of similar creep-resistant steel and steel castings, and its composition meets a Bruscato X-factor of 15 ppm or less.

Applications and selection
This rod is used for tubes, headers and piping in 1Cr-0.5Mo and 1.25Cr-0.5Mo grades such as ASTM A335 P11 and P12 in boilers and refinery heaters. For 2.25Cr-1Mo grades like P22, use . For carbon steel root runs on mixed systems, is the carbon-steel rod. The creep and toughness results above apply to the tempered condition; the data sheet states that as-welded use is possible only under certain conditions, so confirm with the specification.
| Related Böhler TIG rod | AWS / EN ISO class | Typical use |
|---|---|---|
| EMK 6 | ER70S-6 / W 3Si1 | Carbon steel boiler, vessel and structural joints |
| ER 70 S-2 | ER70S-2 | Single-pass work on rusty or rimmed mild steel |
| Union ER 90S-B3 | ER90S-B3 / W CrMo2Si | 2.25Cr-1Mo creep-resistant steel |
Handling and what to confirm
Chrome-moly rods must never be mixed with carbon steel rods, so keep them in the original box and check the rod marking before use. Preheat, interpass control and PWHT are specified by the code for the base metal; the values on the data sheet are a general range, not a substitute for the WPS. When ordering, confirm rod diameter and length (the data sheet lists both 39 in. and 36 in. lengths), the pack weight and the certificate level, and tell us the base metal so the pairing can be checked.

About brand
Böhler Welding is the welding consumables brand of voestalpine Böhler Welding, part of the voestalpine group, with a portfolio that covers stick electrodes, TIG rods, solid wires, gas-shielded and self-shielded flux-cored wires and submerged-arc wires and fluxes. The company states more than 100 years of experience. Seven Star LLC, an independent supplier in Muscat, lists Böhler Welding consumables and welding machines, including pipeline electrodes, and sources Böhler Welding consumables for fabricators and pipeline contractors.
Böhler Welding product groups
Beyond the consumables above, Böhler Welding lists strip cladding, wire arc additive manufacturing, metal powders, arc spraying cored wires, ceramic weld backing, brazing consumables and welding automation such as orbital welding and collaborative robots. The pipeline range includes cellulosic FOX CEL electrodes and basic vertical-down FOX BVD electrodes for large-diameter line pipe.
Ordering Böhler Welding consumables: what we need
Give the product name, the AWS or EN classification, the diameter and length, and the packaging you need. For pipeline electrodes also state the pipe grade, wall thickness, welding position and whether sour-service test values are required, because the Böhler Welding data sheets note that some test values are available on request.
