Kencotube is manufacturer & whole seller for high quality Super Duplex Steel Olets Fittings, where the austenite structure of iron is stabilized. Super Duplex Steel Outlet Fittings have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. Super Duplex Steel Weldolets Fittings have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. Super Duplex Steel Threadolets Fittings have corrosion resistance comparable to austenitic varieties, but can be precipitation hardened to even higher strengths than the other martensitic grades. Super Duplex Steel Sockolets Fittings are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.
The properties of Super Duplex Steel Latrolets Fittings are achieved with overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications. The crystal structure makes Super Duplex Steel Elbolets Fittings virtually non-magnetic and less brittle at low temperatures. For greater hardness and strength, more carbon is added, where with proper heat treatment, these Super Duplex Stainless Steel Outlet Pipe Fittings are used for such products as razor blades, cutlery, and tools. When this is combined, as is often the case, with exposure to saline and other corrosives, it leads to Super Duplex Stainless Steel Olets Pipe Fittings being the material of choice.
