Alloy structural steel can be divided into ordinary alloy structural steel and special purpose alloy structural steel. The former includes low alloy high strength steel, low temperature steel, ultrahigh strength steel, carburizing steels, Quenched and tempered steel and non quenched and tempered steel; and the latter consists of spring steel, ball bearing steel, easy cutting steel, cold 30crmnsi alloy structural steelGB-30CrMnSi Along with steel bars, steel plates and steel tubes supply, steel cutting, drilling, machining and heat treatment services are also provided. JFS Steel has been offering customers special steel materials such as GB-30CrMnSi Manganese Chromium Steels for Machine Structural use and precision steel machining services since 2006.
30CrMnSi high strength quenched and tempered steel plates are used to manufacture all kinds of important parts of high load and high speed, such as gear, shaft, clutch, sprocket, wheel shaft, shaft sleeve, bolt, nut and so on. 30CrMnSi steel is also used to make parts with wear resistance and not too high working temperature features, the variable load welded components, such as the blades of 30crmnsi alloy structural steel
Generally, seamless tubes are made by hot rolling or cold rolling of high quality carbon-bonded steel 16Mn, 5MnV or low alloy structural steel 40Cr, 30CrMnSi, 45Mn2, 40MnB, etc. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transportation pipelines.Steel 30cr, Steel 30cr Suppliers and Manufacturers at 30crmnsi alloy structural steel offers 242 steel 30cr products. About 58% of these are steel pipes, 22% are steel round bars, and 6% are steel sheets. A wide variety of steel 30cr
The special alloy structural steel grade shall be added with the symbol of product use specified in Table 1 at the head (or tail) of the grade. For example, for 30CrMnSi steel for riveting, the steel grade is expressed as ml30crmnsi. The designation of alloy spring steel is the same as that of alloy structural steel.The reinforcement role of deep cryogenic treatment on the 30crmnsi alloy structural steelAt all the three temperatures, for instance, the impact toughness of the 30CrMnSi steel alloy was improved when quenching and tempering were conducted first followed by deep cryogenic treatment. However, impact toughness and tensile strength were respectively enhanced by quenching-tempering-cryogenic and quenching-cryogenic-tempering at a 30crmnsi alloy structural steel
Deep cryogenic treatment (DCT) is believed to have superior performance in coordination with traditional heat treatment. In present work, the effect of DCT combined with inter-critical quenching treatment on the mechanical properties and microstructure of 30CrMnSi alloy structural steel was investigated.The reinforcement role of deep cryogenic treatment on the 30crmnsi alloy structural steelJan 20, 2020The low alloy structural 30CrMnSi steel is widely used in manufacturing important components including sprocket wheels, shafts, clutches, etc. that are subjected to high speed and load conditions . Inter-critical quenching has been considered as an effective method for the toughening of hypoeutectoid steels [ 23 ].
