16 gauge stainless steel tube

Stainless Steel Pipe is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipes and mechanical structure components. In addition, in bending, torsional strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for furniture and kitchenware.

Stainless Steel Round Pipe (SS Round Pipe) is a kind of hollow long round steel. Its cross section is round and is commonly used Stainless Steel Pipe.

Stainless steel pipe: seamless pipe and welded pipe (straight welded pipe, decorative pipe, welded pipe, welded pipe, bright pipe). There are more than 200 standard specifications of stainless steel tubes, all sizes, small tube is more expensive, especially capillary. The capillary should be made of 304 material at worst, otherwise the tube will burst easily. Can also be customized for customers non-standard specifications of pipe. Seamless tube is mainly used in industry, the surface is fog surface, not bright. The surface of the seam pipe is bright surface, and there is a very thin welding line in the pipe, commonly known as welding pipe, mainly used for decorative materials. In addition, the pressure resistance of industrial fluid tubes depends on the wall thickness.310 and 310S are high temperature resistant tubes. They can be used normally below 1080 degrees, and the highest temperature resistance can reach 1150 degrees.

Classification of material
Stainless steel tubes can be divided into Cr system (400 series), Cr-Ni system (300 series), Cr-Mn-Ni(200 series) and precipitated hardening system (600 series) according to the composition. 200 series - Chrome-Nickel-Manganese Austenitic stainless steel 300 series - Chrome-nickel austenitic stainless steel.
301----- Good ductility for molding products. It can also be quickly hardened by machining. Good weldability. The wear resistance and fatigue strength is better than 304 stainless steel.
302----- Corrosion resistance is the same as 304, because the carbon content is higher and thus better strength.
303----- makes it easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304----- is 18/8 stainless steel. The GB brand is 0Cr18Ni9. 309- has better temperature resistance than 304.
316----- The second most widely used type of steel after 304, mainly used in the food industry, pharmaceutical industry and surgical equipment, molybdenum is added to give it a special structure resistant to corrosion. Because of its better resistance to chloride corrosion than 304 stainless steel pipe, it is also used as "Marine steel". SS316 is commonly used in nuclear fuel recovery units. Class 18/10 stainless steel tubing is also usually suitable for this application class.
Model 321- Similar in properties to 304 except for the addition of titanium which reduces the risk of corrosion in the material weld.
400 Series - Ferritic and martensitic stainless steel.
408- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409- Cheapest model (UK or US), usually used as an automobile exhaust pipe, ferritic stainless steel (chromium steel).
410- martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
416- Added sulfur to improve the material's workability.
420-"blade grade "martensitic steel, similar to Brinelli high chromium steel the earliest stainless steel. Also used in surgical knives, can be made very bright.
430- ferritic stainless steel for decoration, e.g. for automobile ornaments. Good formability, but poor temperature resistance and corrosion resistance.
440- high strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common example is the "razor blade". There are three common models :440A, 440B, 440C, and 440F(easy to process).
500 Series- Heat resistant chrome alloy steel.
Series 600 - Martensitic precipitation-hardened stainless steel tubes.
