Subtitle: Φ3-300mm specification range +N4/N6/Ni200/Ni201/Monel400 brand characteristics + chemical/marine/battery/plating 4 categories of application scenarios--Baoji nickel base alloy source manufacturers selection guide
The choice of diameter and brand of nickel rod and nickel alloy rod determines its application adaptability in different corrosion resistance scenarios.From Φ 3 mm thin rod battery tab to Φ 300 mm large specification nickel rod large caustic soda evaporator, accurate matching diameter and brand (such as N6, Ni 200, Monel 400) is the key.Mastering these key points will help scientific material selection, so that the alkali resistance, hydrofluoric acid resistance and seawater resistance of nickel materials can play their due value.
inCaustic soda production, hydrometallurgy, battery manufacturing, marine engineering, electroplating anode, hydrofluoric acid productionOther fields, nickel rods and nickel alloy rods by virtue ofHigh density (8.89g/cm3), outstanding alkali corrosion resistance (corrosion rate in 30% NaOH: 0.025mm/year), hydrofluoric acid (HF dilute acid) resistance, seawater and high-concentration chloride ion resistance, and good biocompatibilityThe unique advantages have become one of the core materials with more applications.
Many people are often selected.Different diameters, various grades, confusion between national standards and American standards, scene differences between nickel and titaniumMake it difficult to choose-in fact, as long as you master the rules of diameter classification, understand the characteristics of commonly used brands, understand nickel rods andtitanium barAccording to the complementary relationship of the scene, the nickel rod and nickel alloy rod suitable for their own needs can be selected scientifically.
Three elements of selectionWorking condition medium (alkali/HF/seawater)+ temperature requirements + standard system (GB/T 5235 vs ASTM B160).Diameter determines load capacity, Grade determines corrosion resistance, Standard system determines purchase specifications, The three cross to lock the better plan.
Combination of industry standards (ASTM B160 / GB/T 5235) and practical application scenarios, nickel rods and nickel alloy rods are usually divided into diametersThin stick, small stick, medium stick, big stickEach of the four categories has its own production process and application field, taking into account practicality and economy.
