It is also suitable for cyaniding and high-frequency quenching beside Q+T. Its machinability also is good, if the hardness is 174-229 HB, the machinability is 60%. 40Cr steel material is a good choice for medium type plastic mold. It belongs to mild Q+T steel and cold heading mold steel. Also, the price is not high, easy to be processed. 40Mn steel product in China, 40Mn steel supplier - Steel SUS 304 steel chemical,JIS G4303 SUS 304 stainless properties; X1NiCrMoCuN25-25-5 steel material properties,EN10088-1 X1NiCrMoCuN25-25-5 stainless suppliers; C55; 25CrM0S4; RINA AH36; Sell AE 235 KR,UNE 36129 AE 235 KR,AE 235 KR steel plate/sheet; E 590-2 Chemical composition, E 590-2 Mechanical properties China Customized 40mnb Structural Alloy Steel Pipe With high strength, hardness, abrasion resistance and good toughness, 40MnB Structural Alloy Steel Pipe is a new type of steel which can replace 40Cr steel successfully.Medium carbon tempered steel, cold upsetting die steel, the steel price moderate, easy to process, after proper heat treatment, can obtain a certain toughness, plasticity, wear resistance, normal can promote the organization spheroidization,

Since the hardenability is improved, the properties of the steel with a thickness of 20 mm or more can be greatly improved after quenching and tempering. Therefore, 40B and 40MnB steel can be used instead of 40Cr, and 20CrMnTi carburized steel can be replaced by 20Mn2TiB steel. What Is An Alloy Alloy Definition Alloy WikiJul 15, 2021 ·  Boron steel:representative steel grades 40B, 45B, 50BA, ML35B. High hardenability, comprehensive mechanical properties higher than carbon steel, equivalent to 40Cr, used to manufacture parts and fasteners with small cross-sectional dimensions.
