AISI 304 316 Tubo Rectangular Steel Tube Pipe 150*100mm 120*60mm

tubo rectangular de acero inoxidable AISI 304 316 stainless steel square pipe tube

Products Description                                                                                                          

The stainless steel tube can be classified into a Cr system (400 series), a Cr-Ni system (300 series), a Cr-Mn-Ni (200 series), 

and a precipitation hardening system (600 series). 200 series - chrome-nickel-manganese austenitic stainless steel,

300 series - chrome-nickel austenitic stainless steel.
301-----extension is good for molding products. It can also be hardened by mechanical processing. Good weldability.

Wear resistance and fatigue strength are better than 304 stainless steel.
302-----corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.
303-----It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304-----that is 18/8 stainless steel. The GB grade is 0Cr18Ni9. 309 - Better temperature resistance than 304.
316-----After 304, the second most widely used steel grade, mainly used in the food industry, the pharmaceutical industry

and surgical equipment,

added molybdenum to obtain a special structure resistant to corrosion.
321 - Other properties are similar to 304 except that the addition of titanium reduces the risk of corrosion of the material weld.
400 series - ferritic and martensitic stainless steel.
408—Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409—The cheapest model, usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
410—Martensite (high-strength chrome steel) with good wear resistance and poor corrosion resistance.
416—The addition of sulfur improves the processing properties of the material.
420—“cutting grade” martensitic steel, similar to the earliest stainless steel of Brinell high chromium steel.
