Ki diferans ki genyen ant 17-4 pH ak 316 SS?
17-4 PH and 316 stainless steels are distinct materials with different strengths and weaknesses. 17-4 PH is a precipitation-hardening stainless steel, known for its high strength and hardness, particularly after heat treatment. 316, on the other hand, is an austenitic stainless steel, renowned for its superior corrosion resistance, especially in chloride-containing environments
Ki sa ki ekivalan a nan 17-4 pH asye pur?
DIN 1.4542: Yon ekivalan Ewopeyen an ki gen menm pwopriyete mekanik. AISI 630: Yon lòt presipitasyon-redi klas asye pur ak karakteristik konparab.

Èske 17-4 pH korozyon rezistan pase 316?
Kontrèman ak 316-L, 17-4PH montre yon rezistans pi ba nan korozyon. Pandan ke toujou apwopriye pou itilize nan anviwònman modera korozivite, li ka nesesite kouch adisyonèl oswa plating. Aplikasyon komen pou 17-4ph gen ladan pati avyon, pati otomobil, ekipman endistriyèl presizyon, angrenaj, ak plis ankò
