Spring steel (GB/T1222-1984)
Spring Steel (GB/T1222-1984)
Spring steel, also known as high-strength carbon-manganese steel, is an ultra-high strength steel used for engineering applications. It is often used in the form of dual-phase micro-alloyed steel, which is manufactured using precise forging processes to ensure uniform......
Grades of Precision Alloys
Precision alloys are metallic materials with special properties such as high strength, corrosion resistance, good electrical and thermal conductivity, low thermal expansion, and other unique characteristics. Precise alloys come in multiple grades and different compositions, and are used in a wide ......
GX20Cr14 application
GX20Cr14 material is a stainless steel with a general level corrosion resistance, higher strength and higher hardenability than GX5CrNi13-4 and GX4CrNi13-4. It is mainly used for cold extrusion and cold heading process forming parts. It can replace chrome-manganese alloys such as GX2CrMnNi, which ......
Classification and grades of quenched metals (GB/T15019-1994)
Classification and Grade of Rapidly Quenched Alloys (GB/T15019-1994)
Rapidly quenched alloys, also known as ultra-high strength alloys, are obtainable by cooling the alloys quickly below the upper critical temperature. Rapidly quenched alloys have higher strength and other properties than commonl......
Romanian Cast Steel No.
Romanias steelmaking industry has its roots in the early 20th century, when an influx of immigrants from other European countries almost doubled its population. Many of these immigrants brought with them skills in metallurgy and the production of steel.
