Alloy Steels pipe
Stainless steels pipe contain a minimum of 11% chromium, often combined with nickel, to resist corrosion. Some stainless steels, such as the ferritic stainless steels are magnetic, while others, such as the austenitic, are nonmagnetic.Corrosion-resistant steels are abbreviated as CRES.
Some more modern steels include tool steels, which are alloyed with large amounts of tungsten and cobalt or other elements to maximize solution hardening. This also allows the use of precipitation hardening and improves the alloy’s temperature resistance.Tool steel is generally used in axes, drills, and other devices that need a sharp, long-lasting cutting edge. Other special-purpose alloys include weathering steels such as Cor-ten, which weather by acquiring a stable, rusted surface, and so can be used un-painted. Maraging steel is alloyed with nickel and other elements, but unlike most steel contains little carbon (0.01%). This creates a very strong but still malleable steel.
Eglin steel uses a combination of over a dozen different elements in varying amounts to create a relatively low-cost steel for use in bunker buster weapons. Hadfield steel (after Sir Robert Hadfield) or manganese steel contains 12–14% manganese which when abraded strain-hardens to form an incredibly hard skin which resists wearing. Examples include tank tracks, bulldozer blade edges and cutting blades on the jaws of life.
Alloy seamless steel pipe
Alloy seamless pipe is a kind of seamless steel pipes, whose property is much higher than the average performance of seamless steel pipe because of high carbon content,The characteristics of alloy seamless pipe with high temperature, low temperature resistance, corrosion resistance make other seamless steel pipe not match.so the more extensive use of alloy tube in the industries of petroleum, chemical, electric power, boiler.
Alloy seamless tubes is mainly used for low pressure boiler (working pressure is generally not more than 5.88Mpa operating temperature below 450 ℃) heating surface tubes; for high-pressure boiler tubes, economizer, superheater, reheater, the petrochemical industry pipe. In addition, alloy steel pipe used in power plants, nuclear power, high-pressure boiler, high temperature superheater and reheater, high pressure high temperature piping and equipment, it is the use of high-quality carbon steel, alloy structural steel and heat-resistant stainless steel material, hot rolled(extrusion, expansion) or cold-rolled (pull) from.
