1.0570, DIN St52-3N, S355J2G3
GENERAL CHARACTERISTIS
This qib steelyog carbon manganese, siab yield tsis alloy steel. Nws yog hu ua S355 vim qhov nruab nrab qhov tsawg kawg nkaus tawm los rau cov khoom no yog 355 Mpa. Raws li cov qauv hlau, nws muaj lub zog zoo heev thiab weldability. Nws tuaj yeem nkag tau yooj yim welded rau lwm cov hlau weldable. Rau nws qis carbon sib npaug, nws muaj cov khoom txias-forming zoo. S355J2G3 feem ntau yog muab nyob rau hauv ib tug normalized mob.

Description Unalloyed structural steel. Daim ntaub ntawv Common structural steel rau welded sib dhos, RNws yog> 355 N/mm2 . Guaranteed toughness ntawm 0O C. Nws tuaj yeem siv rau kev tsim kho statically thiab dynamically stressed. Lub cev muaj zog (qhov nruab nrab qhov tseem ceeb) ntawm qhov kub thiab txias Modulus ntawm elasticity [103x N/mm2Qhov ceev: 210g / cm3]: 7.80 Mos Annealing Kub rau 650-700O C, txias maj mam. Hardening Harden los ntawm qhov kub ntawm 860-890O C ua raws li cov roj los yog dej quenching. Tempering Normalizing kub: 860-890OC. Forging Kub txoj kev kub: 1050-850OC. Machinability Machinability yog qhov zoo, ntsuas ntawm 90% ntawm 1112 alloy siv los ua 100% machining rated steel.
