Puas yog S235JR sib npaug rau A36?
Lub sij hawm "235" yog hais txog qhov tsawg kawg nkaus yield zog (MPa) rau steel thickness tsawg dua 16 hli. Lub "JR" qhia txog lub zog-txog qib zoo ntawm Charpy impact test (27 J, 20℃kub). ASTM A36 cov khoom sib npaug rau cov hlau S235JR.
S235JR steel qib yog dab tsi?
S235JR yog cov khoom siv dav dav, tus nqi - zoo, tsis yog - alloy structural steel (EN 10025 tus qauv) paub zoo weldability thiab formability, qhia los ntawm nws qhov tsawg kawg nkaus 235 MPa yield zog (S) thiab 27 Joule cuam tshuam lub zog kuaj ntawm chav tsev kub (JR), ua rau nws tsim nyog rau kev siv lub tshuab, kev siv lub tshuab, thiab kev tiv thaiv corrosion. tiv as nws tsis yog inherently stainless.
JR sawv cev rau dab tsi hauv S235JR?
S235JR: Ib hom hlau uas nquag siv, S235JR paub txog nws qhov weldability, machinability, durability, thiab hnav- ua haujlwm. Nws cov lus "JR" qhia tias nws qhov cuam tshuam tsawg kawg nkaus yog 27 joules thiab nws tau dhau los ua qhov kev ntsuam xyuas ntawm 20 degree.
