1. introduction of the main steel grades of high temperature resistant and high corrosion resistant alloys(904l, 253ma, 254sm0, 800/800h, 825, 400, 600, 625, c276)high-temperature resistant alloys are generally: 309s, 310s, 800, 825, 600, 625high corrosion alloys are generally: 317l, 904l, 254sm0, 8

common knowledge of surface treatment of stainless steel (1), overview of surface treatment of stainless steel has a unique strength, high wear resistance, superior corrosion resistance, and not easy to rust and other excellent characteristics. therefore, it is widely used in the chemical industry,

 1 difficulties in processing stainless steel1.1 high cutting force and high cutting temperaturethis type of material has high strength, large tangential stress, and large plastic deformation during cutting, so the cutting force is large. besides, the material's thermal conductivity is extremel

the so-called nickel-based alloy refers to an alloy based on nickel and added with other metals, such as tungsten, cobalt, titanium, iron, and other metals. there are many types of nickel-based alloys according to different classification methods. according to the matrix, nickel-based alloys can be

demand and production of stainless steel welded steel tubes for automobilesin recent years, with the continuous increase of service life and exhaust temperature, automobiles have put forward higher requirements on the local corrosion resistance of the cold end of the exhaust system and the high temp

the application of stainless steel in the automotive industry can be roughly divided into five categories: stainless steel for automobile exhaust systems, stainless steel for automobile fuel tanks, stainless steel for automobile frames, stainless steel parts for automobile and stainless steel for au

stainless steel pipe flange and fitting manufacturing companies should consider the cost of pipe fittings, but should also consider preventing corrosion and improving product quality.factors, therefore, the solid solution process is adopted in the stainless steel pipe flange manufacturing process to

austenitic stainless steel is softened by solution treatment. typically, a stainless steel tube is heated to approximately 950 ~ 1150 ° c.for some time, carbides and all kinds of synergistic elements completely and uniformly dissolve in austenite, and then quickly cool when cooled by water, carbon a

17-4 stainless steel17-4 stainless steel, also known as sae type 630, is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. the numbers “17-4” refer to its composition: ≈17% chromium and ≈4% nickel. it also can include between 3 and 5% copper.
