Tshebetso le Matla a Mekaniki

ASTM A516 (Dikereiti tsa 60-70) e fana ka matla a tlhahiso a 260–290 MPa le matla a ho thaepa ho fihlela ho 550 MPa, hammoho le ho tiea ha mocheso o tlase ho fihlela ho -45°C. Ha ho bapisoa:

ASTM A36– Matla a tlhahiso 250 MPa, ho thapolla 400–550 MPa, tshebetso e akaretsang mochesong o tlase.

ASTM A572 (Gr.50)– Tekanyo ea 345 MPa, ho thapolla 450–620 MPa, ho tjheseletsa hantle le ho tiea mochesong o tlase.

Q355– Tekanyo ea 355 MPa, e tenyetsehang 470–630 MPa, e sebelisoa haholo mererong ea kaho ea Chaena ka lebaka la matla a eona a phahameng le ho tšoarella.
