What material is SF-2000 LQ40
I believe that many people no matter how to search, want to find the relevant information of SF-2000 LQ40 this material is difficult and difficult, then in the end SF-2000 LQ40 is what material, SF-2000 LQ40 is what steel, now I will give you a professional answer.
In fact, SF-2000 LQ40 die STEEL is Canada's Dory (SOREL FORGE STEEL) die steel. SF-2000 LQ40 die steel is a pre-hardened die steel, electroslag remelting steel, its pre-hardened hardness is 38-42HRC, Brinell hardness is 355-390HB, tensile strength is 1202-1322.
SF-2000 LQ40 die steel has good impact strength and good tempering stability, and the hardness of large-size workpieces is very uniform.
SF-2000 LQ40 die steel features are as follows:
• Excellent polishing;
• Good machinability;
• Very uniform hardness;
• High purity, uniform organization;
SF-2000 LQ40 die steel is 100% subjected to very rigorous ultrasonic testing to ensure very high quality.
SF-2000 LQ40 die steel has a very uniform composition distribution and metallographic structure. The uniform tempered martensite and bainite structure guarantees excellent polishing properties. The SF-2000 LQ40 is forged with a 5,000 ton wide-body forging press to ensure that the billet center can achieve maximum deformation during the forging process. SF-2000 LQ40 die steel undergoes a special densification forging process during forging to ensure the density of the central structure. SF-2000 LQ40 die steel is an excellent etch material. The electroslag remelting process removes almost all segregation, and the high purity of SF-2000 LQ40 die steel ensures a high quality surface. High quenching ensures the hardness of the machined surface. The ultra-low sulfur content and very uniform microstructure ensure that the SF-2000 LQ40 die steel will achieve SPI A-1 surface quality after A reasonable polishing process.
