PRODUCT CENTER
High temperature wear tests for 3Cr2W8V steel were performed by a pin-on-disk high temperature wear apparatus.The effects of quenching temperatures on wear resistance of 3Cr2W8V steel were studied.The compositions,images and structure of worn surfaces were analyzed using SEM,EDS and XRD.
AISI 4140 Alloy Steel is a common chromium-molybdenum steel that usually used after quenched and tempered, with high intensity, high hardenability. The alloy 4140 plate also has high fatigue strength and good low-temperature impact toughness.
GB 40CR alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc. GB 40CR steel Annealing delivery hardenss less than 250HB.40CR With a lower carbon content range, So GB 40CR alloy steel have good weldability.
AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.
42CrMo steelbelongs to plastic mold steel in mold steel from the perspective of material classification. It has good mechanical properties and machinability, and is widely used. There are mainly two types of materials, plate and round bar. Plate is used for mold processing Production, round rods are used to machine parts directly, which has been recognized by the industry.
