Good Quality 316 Stainless Steel Tube - Multi-material high quality stainless steel tube – Hongmao Detail:
Product introduction
According to the composition of stainless steel tube can be divided into Cr (400 series), CR-Ni (300 series), CR-Mn-Ni (200 series) and precipitation hardening system (600 series).
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 mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
302—– corrosion resistance and 304, due to relatively high carbon and therefore better strength.
303—– makes it easier to machined than 304 by adding a small amount of sulfur and phosphorus.
304—– is 18/8 stainless steel. The GB brand is 0Cr18Ni9. 309 – better temperature resistance than 304.
316—–, the second most widely used steel after 304, is mainly used in the food industry, pharmaceutical industry and surgical equipment, with the addition of molybdenum to give it a special structure that is resistant to corrosion. It is also used as “Marine steel” because of its better resistance to chloride corrosion than 304 stainless steel tubes. SS316 is usually used in nuclear fuel reprocessing units. Class 18/10 stainless steel tubes are also usually qualified for this application class.
Model 321 — Similar to 304 except that titanium is added to reduce the risk of weld corrosion.
400 series — ferrite and martensitic stainless steel.
408 — Heat resistance, mild corrosion resistance, 11% Cr, 8% Ni.
409 — cheapest model (Anglo-American), usually used as automobile exhaust pipe, ferritic stainless steel (chrome).
410 — Martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
416 — Sulfur was added to improve the machinability of the material.
420 — “blade grade” martensitic steel, similar to brinell high chromium steel, the earliest stainless steel. Also used for surgical knives, which can be made very bright.
430 — Ferritic stainless steel, for decorative purposes, e.g. automotive accessories. Good formability, but poor temperature and corrosion resistance.
440 — high strength cutting steel, slightly high in carbon, with appropriate heat treatment to achieve a high yield strength, hardness up to 58HRC, is among the hardest stainless steels. The most common example is the “razor blade”. There are three common models: 440A, 440B, 440C, and 440F (easy to process).
500Series – Heat resistant chromium alloy steel.
600 series – Martensite precipitation hardened stainless steel tubes.
