Quality standards for steel surface cleaning
Quality Standards for Surface Cleaning of Steel
Surface cleaning of steel is an important part of the manufacturing process of steel products. It is important to clean any contaminants from the surface of the steel before it is formed or machined. This helps to ensure the quality of the finished ......
Lead anode plate GB 1471-88
Lead Anode Plate
The lead anode plate is a metal plate made from lead or lead alloy which used for electrolytic industrial water treatment and electroplating. Lead anodes are widely used in water treatment because of the great corrosion resistance of lead in saltwater.
Lead anode plates can be u......
Deformed permanent magnet steel GB/T 14991-94 replaces GBn 174-82
Introduction
The GB/T 14991-94 replace GBn 174-82, is a new standard with improved characteristics and performance. The new standard requires an increased strength level that allows much less material to be used in order to achieve the same strength. This requires a greater focus on manufacturing......
Titanium and titanium alloy cake material GBn 194-83
Introduction
Titanium is a white lustrous metal with very low density, great strength, high corrosion resistance and excellent properties at elevated temperatures. Titanium and titanium alloys find wide application in the aerospace, chemical, petrochemical, marine and medical industries due to th......

The Role of Automotive Urea SCR Catalytic Converters in Reducing Pollutant Emissions
The auto industry is under increasing pressure to reduce the level of air pollution caused by the combustion of fossil fuels in the engines of the vehicles they produce. One of the primary techniques for reducing......
Chemical composition and mechanical properties of weld metal with different grades of welding wire
Welding electrodes are made of steel and applied with a superior form of wire for combining two or more metal objects. Electronically and chemically, there is no inflexible regulation over their manufacture, and therefore the compositions and mechanical properties of different models are varied an......
Application of GX40NiCrSiNb35-25
Inconel GX40NiCrSiNb35-25 is a highly alloyed, corrosion-resistant superalloy particularly suited for high-temperature applications. The alloy is composed of nickel, chromium, silicon, and niobium with additional trace elements of iron, manganese, cobalt and molybdenum. This combination creates a ......
X210CrW2 use
X210CrW2 Introduction
X210CrW2 is a type of high alloy martensitic stainless steel. It has a considerably high corrosion resistance and good toughness ability than most other martensitic stainless steels. These properties are due to its low C and high Cr/Mo content, which makes it well suited for......
