ASTM E436 Drop-Weight Tear Test (DWTT) for Ferritic Steels

← Back to all standards

ASTM E436 is the test method for the drop-weight tear test (DWTT) of ferritic steels. To match this to your program, talk with our team.

What ASTM E436 Covers

It evaluates the fracture appearance and resistance of steel, especially line-pipe steel, to running brittle fracture at low temperature.

How the Test Is Run

A notched full-thickness specimen is broken by a falling weight, and the percentage of ductile (shear) fracture on the surface is assessed against requirements.

Why It Matters

DWTT results govern acceptance of pipeline and structural steels for fracture control; a drop-weight machine sized for the specimen is required.
