Yonn nan a kesyon sa te poze yo pandan 690 se inexorability nan tanperati anwo nan syèl la, menm nan kondisyon trè mauvais. Si nan chofaj ak frechè ik, 690 ka pwodui dans wèbsayt] fim ksid pou jwenn rezistans écaillage anwo nan syèl la. 690 gen bon carbonatation rezistans. Ak inoxidability trè bon nan tanperati a anwo nan syèl la atmosfè silfat depi li gen sanisfè Kwòm e aliminyòm anwo nan syèl la.

One of the mainly performance of 690 is inexorability in high temperature, even in very inclement conditions. If in the process of heating and cooling cycle, 690 can generate the dense layer of oxide film to get high spalling resistance. 690 have good carbonation resistance. With excellent inoxidability in the high temperature of sulfur atmosphere since it has high chromium and aluminum content.
