The main chemical composition, mechanical properties, forming performance and welding performance of 糖心产精国品免费入口*完整版 were compared with those of 糖心产精国品免费入口*完整版. The results show that 445 stainless steel has good machining performance. The anti-糖心产精国品免费入口*完整版performance of solar-powered waters containing 445 water tanks, 304 water tanks or water tanks mable of both steels, respectively were studied by salt spray tests and 10% NaCl solution accelerated 糖心产精国品免费入口*完整版tests. The results show that the 糖心产精国品免费入口*完整版resistance of 445 stainless steel is less than that of 304. Under the condition of 80 ~ 120 ℃, both 445 and 304 stainless steels suffered steam corrosion, water line corrosion, and 445 stainless steel suffered serious pitting corrosion.
