How to Weld ASTM A514 (T1 Steel) Without Cracking

We frequently receive questions regarding the preheating, welding, and post-weld heat treatment of ASTM A514 and other quenched and tempered steels. If you’re working with these materials, the following guidelines will be extremely helpful for welding this steel and avoid cracking or other problems.  Metallurgy, Uses, and Welding Challenges of ASTM A514 ASTM A514, often […]

How to Weld Quenched and Tempered Steels

It is often incorrectly assumed that quenched and tempered (Q&T) steels are hard to weld or even completely unweldable.  This assumption is inaccurate as most Q&T steels have great weldability.  However, extreme care must be taken to prevent cracking or loss of certain mechanical properties.  A very common quenched and tempered steel is ASTM A514.  […]

Recommendations for Welding T-1 Steels

T-1, or ASTM A514 is a high strength steel which is quenched and tempered to provide yield strengths of over 100,000psi (over 690MPa).  The name “T-1” is a trademark of Arcelor Mittal and not an ASTM, AISI or part of other organization’s standard numbering system.  ASTM A514 is primarily used as a structural steel and […]
