Silicon Nitride Ceramic Ring:
The multi-element alloy formed by adding other alloying elements to Silicon Nitride Ceramics is called special brass. Commonly added elements include lead, tin, aluminum, etc., which can be called lead brass, tin brass, and aluminum brass accordingly. The purpose of adding alloying elements. Mainly to improve the tensile strength and improve the manufacturability.
Code: It means "H + the symbol of the main element (except zinc) + the mass fraction of copper + the mass fraction of the main element + the mass fraction of other elements".
For example: HPb59-1 means that the mass fraction of copper is 59%, the mass fraction of lead containing the main element is 1%, and the balance is lead brass with zinc. Thermal processing temperature is 750～830℃; annealing temperature is 520～650℃; low temperature annealing temperature to eliminate internal stress is 260～270℃.
Environmental protection brass C26000 C2600 has excellent plasticity, high strength, good machinability, welding, good corrosion resistance, heat exchanger, paper pipe, machinery, electronic parts.
Specifications (mm): Specifications: thickness: 0.01-2.0mm, width: 2-600mm;
Hardness: O, 1/2H, 3/4H, H, EH, SH, etc.;
Applicable standards: GB, JISH, DIN, ASTM, EN;
Specialty: Excellent cutting performance, suitable for high-precision parts processed by automatic lathes and CNC lathes. Stainless Steel (Stainless Steel) is the abbreviation of Silicon Nitride ceramics. Steels that are resistant to weak corrosive media such as air, steam, and water or are stainless steel are called stainless steel; Corrosion steel is called acid-resistant steel.
Due to the difference in chemical composition between the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive. The term "stainless steel" not only refers to a single type of stainless steel, but also refers to more than one hundred industrial stainless steels. Each stainless steel developed has good performance in its specific application field. The key to success is to understand the purpose first, and then determine the correct steel grade. There are usually only six steel grades related to the application of building construction. They all contain 17-22% chromium, and better steel grades also contain nickel. The addition of molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance of the chloride-containing atmosphere.
Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
