S355 thiab Q355 yog ob qho tib si tsim rau cov qauv hlau, tab sis lawv los ntawm cov qauv sib txawv thiab muaj qee qhov sib txawv ntawm lawv cov specifications thiab kev siv.
S355 hlau
Txheem: EN 10025-2 (European Standard)
Qib: S355
Nqe lus piav qhia: S355 yog lub zog muaj zog, qis-alloy structural steel nrog qhov tsawg kawg nkaus lub zog ntawm 355 MPa. Nws yog feem ntau siv rau hauv kev tsim kho thiab kev siv cov txheej txheem vim nws zoo weldability thiab machinability.
Common Subgrades:
S355JR: General structural steel nrog qhov tsawg kawg nkaus yield zog ntawm 355 MPa thiab cuam tshuam lub zog ntawm 27J ntawm chav tsev kub.
S355J0: Yam tsawg kawg nkaus lub zog ntawm 27J ntawm 0 ° C.
S355J2: Yam tsawg kawg nkaus lub zog ntawm 27J ntawm -20 ° C.
Q355 Hlau
Txuj: GB / T 1591 (Suav Txuj)
Qib: Q355
Nqe lus piav qhia: Q355 yog cov qauv hlau muaj zog nrog qhov tsawg kawg nkaus ntawm 355 MPa, zoo ib yam li S355. Lub "Q" sawv cev rau "Qu" (yield point), thiab "355" yog hais txog qhov tsawg kawg nkaus tawm lub zog hauv MPa.
Common Subgrades:
Q355B: Tsawg kawg cuam tshuam lub zog ntawm 27J ntawm 20 ° C.
Q355C: Yam tsawg kawg nkaus lub zog ntawm 27J ntawm 0 ° C.
Q355D: Yam tsawg kawg nkaus lub zog ntawm 27J ntawm -20 ° C.
