Congratulate, what: 3hrc

Compared with ordinary steel, special steel 3hrc higher strength and toughness, physical properties, chemical properties, biocompatibility 3hrc process properties. Compared with ordinary steel, special steel has the characteristics of high purity, high uniformity, ultra-fine organization and high precision: 1 High purity.

Targeted to reduce the content of gas and inclusions with low melting 3hrc metal 3hrc in steel. The purity of steel can not only greatly improve the original 3hrc of steel, but also give the steel a new performance. For example, if the oxygen content in the bearing steel is 3hrc from 30 x to 5 xthe bearing life is increased by 30 times. Phosphorus in general Austen stainless steel is reduced to 3 x and see more immune to stress corrosion. The purity level 3hrcc steel that can be achieved by large-scale production at the end of the 20th century is: hydrogen: hydrogen, oxygen, carbon, sulfur, 10, nitrogen, 15, phosphorus, The analysis of steel components leads to uneven steel tissue and performance, which is one of the important reasons why steel parts fail early and steel performance potential is difficult to give full play.

Modern 3hrc process should achieve the uniformity of steel: car gear steel 3hrc band fluctuations of. The mechanical properties of the vertical, horizontal and thickness directions of the anti-layered tearing steel z-to-steelespecially the plastic and toughness requirements are generally the same.

Ultra-fine tissue reinforcement 3hrc the only reinforcement mechanism that increases steel strength without reducing toughness 3hrc slightly increasing toughness. For example, the grain 3hrc high-strength stainless steel AFC77 is refined from 60 m to 2. When the pressure vessel steel plate of the nuclear reactor is coarse crystal, the irradiated brittle temperature range is to degrees C and the fine crystal steel is reduced to 50 to 70 degrees C. The carbide in the bearing steel is fine to.

Special steels should have good surface quality and narrow dimensional tolerances. The precision of hot-rolled steel rods has reached.

The world has nearly Special steel gradeabout 50, varieties of specifications. In addition to a wide variety of special 3hrc, zhi also exhibits different dao characteristics from ordinary steel in specifications. In addition to plates, tubes, silk, belts, rods and profiles, there are composite materials, surface alloying materials, surface treatment materials, fine forging materials, precision castings, powder metallurgical products. Steel brand name referred 3hrc as steel number, 3hrc the name of each specific steel product, is a common language that people understand steel.]
