Designated as UNS N06035 or DIN 2.4643, Alloy G-35 is a nickel-chrimium-molybdenum alloy designed to resist “wet process” phosphoric acid, which is used in the production of fertilizers. Similar to Hastelloy G-30, G35 alloy also has excellent resistance to localized attack in the presence of chlorides, since this can be a problem beneath deposits in evaporators used to concentrate “wet process” phosphoric acid. Besides, it is much less susceptible to chloride-induced stress corrosion cracking than the stainless steels and nickel-chromium-iron alloys traditionally used in “wet process” phosphoric acid. Due to the high chromium content, Hastelloy G-35 is high to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, as a result of its appreciable molybdenum content, and, unlike other Ni-Cr-Mo alloys, it is very resistant to “caustic de-alloying” in hot sodium hydroxide.
Steel plates are divided into thin steel plates <4 mm (the thinnest is 0.2 mm), medium and thick steel plates 4~60 mm, and extra thick steel plates 60~115 mm according to thickness. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of thin plates is 500~1500 mm; the width of thick plates is 600~3000 mm. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates according to steel types; according to professional uses, there are plates for oil drums, enamel plates, etc.; according to surface coatings, there are galvanized thin plates, tinned thin plates, lead-plated thin plates, plastic composite steel plates, etc.
