Ki sa ki estanda ASTM A249?
ASTM A249 se yon spesifikasyon estanda pou tib asye austenitic soude yo itilize kòm chodyèr, surchofaj, echanjeur chalè, ak kondansateur. Li kouvri kondisyon chimik ak mekanik, tès, ak kontwòl kalite pou tib sa yo, ki disponib nan divès klas tankou TP304, TP304L, ak TP316L. Spesifikasyon an defini seri gwosè, tolerans dimansyon, tretman chalè, ak kondisyon fini sifas pou tib yo.
ASTM A249 TP304 spesifikasyon
ASTM A249 TP304 se yon spesifikasyon pou soude tib asye pur austenitic yo itilize nan aplikasyon tankou chodyèr, echanjeur chalè, ak kondansateur. Li mande pou yon fòs rupture minimòm de 515 MPa, yon fòs sede minimòm de 205 MPa, ak yon elongasyon minimòm de 40% nan 50mm. Spesifikasyon an kouvri materyèl, dimansyon, tolerans, tès, ak kondisyon livrezon pou tib sa a, ki pwodui nan bann plat-woule epi souvan byen klere pou yon sifas pwòp.

Evalyasyon presyon tib soude pou ASTM A249
Ki diferans ki genyen ant ASTM A269 ak A249?
ASTM A249 mande pou soude a frèt -travay apre soude, ak anvan tretman final chalè. ASTM A269 pa egzije okenn travay frèt oswa kontwòl soude. ASTM A270 pa mande pou pèl soude. ASTM A554 ka apwovizyone ak chaplèt la soude kite sou, e pakonsekan li konfòme ak opsyon "Chaplèt Retire" nan A554.
Ki diferans ki genyen ant ASTM A249 ak A213?
ASTM A249 se yon spesifikasyon estanda pou chodyè asye austenitic soude, sipèchofaj, echanjeur chalè -, ak tib kondansateur. ASTM A213 se yon spesifikasyon estanda pou chodyè asye pur feritik ak austenitic alyaj -, surchofaj, ak tib echanjeur chalè-.
