1, Ki sa ki korespondan nouvo estanda pou ST52-3? Èske li ka ranplase pa S355JR / S355J2?
Repons: ST52-3 se ansyen estanda Alman DIN 17100, ak korespondan nouvo estanda Ewopeyen an se S355JR / S355J2.
ST52-3 ≈ S355JR (chòk tanperati chanm)
ST52-3 J2 ≈ S355J2 (-20 degre chòk) Pwopriyete mekanik yo, konpozisyon chimik, ak aplikasyon yo se fondamantalman menm bagay la tou, epi yo ka dirèkteman ranplase youn ak lòt.
2, Èske ST52-3 ka soude dirèkteman? Ki prekosyon yo ta dwe pran lè soude?
Repons: Wi, ST52-3 gen ekselan soudabilite.
Low kabòn ekivalan, pa gen tandans fè fann.
Preheating is generally not required. For thick plates (>40mm) oswa nan anviwònman tanperati ki ba -, prechofaj a 80-120 degre posib. Yo ka itilize baton soude konvansyonèl yo, soude ki pwoteje gaz, ak soude arc submerged.
