  1. jewelry wholesale gift boxes The inner diameter of the straw must be small. Because the inner diameter is small, the liquid molecules crawl on the inner wall of the tube will generate a upward pulling force and lift a certain weight liquid. If the inner diameter is too large, the liquid cannot be lifted. Because the size of the hair is used to describe the small inner diameter, its phenomenon is called
    .

  2. custom made jewelry boxes wholesale Stainless steel is a modern material with a 60 -year development process
    has inventing stainless steel since the beginning of this century, stainless steel has collected the image of modern materials and outstanding reputation in architectural applications, making their competitors envious.
    As long as the selection of the steel type is correct, the processing is appropriate, and the maintenance is appropriate, the stainless steel will not produce corrosion, erosion, rust or wear. Stainless steel is also one of the most intensity materials in the building. Because stainless steel has good corrosion resistance, it can keep the structural components permanently maintain the integrity of engineering design. Chromium -containing stainless steel also collects mechanical strength and high extension, and is easy to process and manufacture of components, which can meet the needs of architects and structural designers.
    In buildings, buildings and structure industries, the key to the success of stainless steel is that it has good corrosion resistance.
    The stainless steel plate sub-group
    200
    series-chromium-nickel-manganese
    Stainless steel
    model
    301 — has good ductility and is used for molding products. It can also be hardened by mechanical processing. Welding is good. Abrasion and fatigue strength is better than 304 stainless steel.
    model
    302 —The corrosion resistance is the same as 304, because the carbon content is relatively high and the intensity is better.
    Model
    303 — By adding a small amount of sulfur and phosphorus, it is easier to cut and process than 304.
    model
    304 — General model; that is, 18/8 stainless steel. The GB brand is 0CR18NI9.
    model
    309 — has better temperature resistance than 304.
    Model
    316 — Following 304, the second steel type that is widely used is mainly used for the food industry and surgery equipment, add molybdenum element to obtain a special structure of corrosion. Because it has a better anti -chloride corrosion ability than 304, it is also used as "ship steel". SS316 is usually used in nuclear fuel recycling devices. Level 18/10 stainless steel usually meets this application level. [1]
    Model
    321 — Except for adding titanium elements to reduce the risk of risk of material welding rust, other properties are similar to 304.
    400
    series -iron body and martensite stainless steel
    model
    408 -good heat resistance, weak resistance to corrosiveness, 11%CR, 8%NI.
    model
    409 — the cheapest model (Britain and America), usually used as a car exhaust pipe, which is ferrite stainless steel (chromium steel).
    model
    410 -martensite (high -strength chromium steel), good abrasion resistance and poor corrosion resistance.
    Model
    416 — Add sulfur to improve the processing performance of the material.
    Model
    420- "Blade Grade" Ma's Steel Steel, the earliest stainless steel like Bu's high chromium steel. It is also used for surgery tools and can be done very bright.
    model
    430 — iron stainless steel, decorative, for example for car jewelry. Good molding, but poor temperature resistance and corrosion resistance.
    Model
    440 — High -strength blade steel, which is slightly high in carbon. After appropriate heat treatment, you can get higher yield strength. The hardness can reach 58HRC, which is the hardest stainless steel. The most common application examples are "shaving blades". There are three common models: 440A, 440B, 440C, and 440F (easy to process).
    500
    series -heat chromium -resistant alloy steel.
    600
    series -martensite precipitation hardening stainless steel.
    model
    630 — The most commonly used sedimentary hardening stainless steel model is usually 17-4; 17%CR, 4%Ni.
