Steel T1 vs T2

Steel · grade comparison

Steel T1 and T2 are both steel grades. Both yield at about 560 MPa — strength does not separate them. On the shop floor, T1 sits in a lower cost tier (premium, $$$) than T2 (high, $$$$).

T1 vs T2 — frequently asked

What is the difference between T1 and T2?

Steel T1 and T2 are both steel grades. Both yield at about 560 MPa — strength does not separate them. On the shop floor, T1 sits in a lower cost tier (premium, $$$) than T2 (high, $$$$).

Which is cheaper, T1 or T2?

T1 is the lower-cost material: it sits in the premium tier ($$$) while T2 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which welds better, T1 or T2?

T2. Its weldability rates poor (20/100) against poor (15/100) for T1.
