Lè w ap achtePlak echanjeur plak, chwa a nan materyèl dirèkteman afekte efè a itilize ak lavi . Premye a se asye pur, tankou 304 ak 316 asye pur yo trè komen . 304 asye pur gen bon rezistans korozyon ak pri modere, ki se apwopriye pou kondisyon travay òdinè san yo pa medya korozif fò, tankou sistèm chofaj; 316 asye pur gen MOLYBDENUM te ajoute, ki se plis korozyon rezistan ak se itilize plis nan endistri tankou pwodwi chimik yo, manje ak bwason ki gen kondisyon segondè pou ijyèn ak rezistans korozyon .
Titanium is also a high-quality choice. It has a particularly strong corrosion resistance, especially in seawater and chlorine-containing media environments, but the price is relatively high. Nickel-based alloy materials are suitable for extreme working conditions with high temperature and high corrosion. They can work stably for a long time under harsh conditions, but the cost is also the Pi wo . Dapre senaryo a l 'espesifik ak karakteristik mwayen, konsiderasyon konplè nan rezistans korozyon, rezistans tanperati ki wo, pri ak lòt faktè ka fèt yo chwazi plak la echanjeur plak nan materyèl la dwa .
